HOW TO FIND A CLOG IN YOUR CARS A/C SYSTEM

In today's video we take a look at a 2009 Honda Odyssey w/ a 3.5 V6 engine. The owners complaint is that the air conditioning is not cooling even though they already charged it with refrigerant. The other symptom they have is that while the a/c is running, freon or refrigerant blows out of the back of the compressor. Refrigerant shooting out of the pressure relief valve is a sign that the system has a major clog or blockage. Watch and find out how you can locate a blockage in your a/c system using a thermal temperature gun.

Just FYI my explanation of how the A/C system works is very simplified and meant for a general understanding of how an expansion valve works. I know some of you very educated viewers may give me a hard time. I’m just trying to help the regular Joe diagnose and fix his or her A/C this summer. Thanks for watching!

[@MattyEngland]

It was a great explanation in terms of solving the problem and fixing the car. That is what 99.9% of people are here for, anyone who wants to go more in depth can go to Wikipedia or an HVAC channel.

[@ADVANCEDLEVELAUTO]

[@713jtmechanic8]

Great explanation! I like you corrected yourself saying refrigerant, instead of freon. That took a long time for me to break the habit of calling it freon. For your youtube community. Freon is R12. Freon is the brand of Dupont. It would not matter if you called freon your viewers understand. Its difficult to create video content and explain the work you are preforming. A lot of brain power.

[@abechavez1876]

Yep, called high pressure relief valve to prevent the compressor and or evap, condenser to rupture blow with much force. Located directly right on the back side of compressor itself

[@DieselRamcharger]

@@abechavez1876 its there to stop the evap from popping and venting all the gas inside the passenger compartment which would cause an accident, kill somebody and be a massive liability for the auto maker.

[@aaronmcdonald4944]

Phenomenal. I learnt how to better trace a clog. I knew how to diagnose clogs, but i wasn't too sure on how to determine where the clog was. The only thing I can say is refrigerant enters and leaves the compressor in vapor form, not a liquid. liquids cannot be compressed. Thank you

[@creamofbotulismsoup9900]

It may be possible that there was something wrong with that compressor, it may have been damaged if it was building up enough pressure to trip to relief valve. Likely not catastrophic but it may have reduced its lifespan. Kind of hard to know with these things.

[@DieselRamcharger]

[@ibkoool1]

Great diagnostic technique as usual dude. To clarify one thing, an A/C compressor is not design too and should not be allowed to pump liquid, pumping liquid damages an A/C compressor. The compressor discharges vapor into the condenser and the condenser, as the name implies “CONDENSER” condenses the vapor into a liquid.

[@ryantidwell9608]

Great diagnosis! Exceptional job of explaining how a vehicles a/c works & the inner workings of the refrigerant process!

[@bigdaddymak1439]

One little correction the refrigerant coming out of the compressor is a gas it doesn't become a liquid until in goes through the condenser. IE it condenses the gas! Great videos bud!!

[@isettech]

Correction, where there is a restriction, the condenser stops flowing and fills with condensed gas which is liquid. When the relief opens, the liquid boils and sprays a mix of liquid and gas. Safety first. Getting sprayed by this can cause severe frostbite. Think taking the radiator cap off an overheated car. Boiling liquid blows out under force. Same principal, but with refrigerant. Both are dangerous to get sprayed with.

What a great demonstration, of the compressor saving itself from overload by releasing refrigerant. I've never seen that before.

[@smcool100]

When this happens will this automatically mean compressor or system damage? I filled my truck w/ R134a and I had this happen (blowout through relief valve twice). I then bled the system to bring down the pressure. I seem to be getting coldish air again and no more blowout. But I have and am seeing big pressure spikes in ac system.

[@MLML606]

Glad I found this video almost recharged my truck thank you sir

[@yomomma9070]

Eric, you are very intelligent and your video are inspiring and educational. Just FYI, the compressor discharges a high temp, high press GAS. As the gas enters the condenser and it gives up its heat to the ambient air, the gas condenses into a liquid. The expansion device is the dividing point from high to low press. You are correct in the diagnosis and procedures of finding restrictions. Large press/temp difference indicates restriction and will work like a metering device/TXV/orifice. A good practice when replacing compressors is to replace the micro-channel condenser with it. It is impossible to flush debris out of them due to the paralel construction. Keep up the great work and I look forward to your vids.

[@jaycart5105]

Yo mamma, your comment around the compressor is correct . Compressor is normally supposed to discharges high pressure hot gas into the condenser. The gas is then cooled by the air blowing across the condenser air, and it turns the gas into high pressure liquid (condensing the gas, hence the word condenser)

[@holoxfauxfecs5651]

I love the drawings to explain how the AC system works. They helped me a lot!

[@gregjones8501]

That’s crazy! I have two of the same vehicles in my shop at the same time!

[@jmtolentino6397]

when the compressed refrigerant comes out of of the compressor it's still in gas form, it will only becomes liquid when it's cooled down inside the condenser hence the term. then the cold part in the condenser is caused by the clog. because of the clog, the pressure in the high side is low.. the lower the temperature the colder the refrigerant will be as per the pressure/temperature relationship properties of the said refrigerant.... still good job diagnosing the problem, didn't occur to me to use a temp gun, and i didn't know that there is a relief valve on the compressor. thanks for the added knowledge

[@freddyhollingsworth5945]

05:55 I agree the AC condenser is the cause of the restriction, but I bet too many of the the micro channels are clogged with debris from the previous failing AC compressor... I really don't think that one dent in the bottom of the condenser can cause the whole condenser to "clog"? Great video!!!

[@madmatt2024]

The big question now is, why did the condenser plug up? The small bend at the bottom wouldn't have crushed enough rows to cause a blockage like that. That leaves the compressor failing at some point or the desiccant bag inside the dryer coming apart. Both of which will probably cause trouble down the road if the car lot didn't flush the system.

[@ADVANCEDLEVELAUTO]

I'm not entirely sure. That is why I recommended that they flush the system out when they replaced the condenser. Thanks for watching!

[@ratbag359]

The last row is on the bottom and was crushed. it comes in on the top and snakes down. in ________________________________________ ________________________________________| |________________________________________ out ________________________________________|

[@abechavez1876]

Exactly how Josh C explained. This type of A/C condenser has the one inlet at towards the top first row then it loops zig zags down from side to side horizontally until it exits outlet line at the bottom most row which makes sense as it was crushed bent upwards as shown in video. It circulates differently than a radiator, where coolant entering can go flow in all rows across and it exits flows out all rows on other end simultaneously from all rows.

[@madmatt2024]

@@ratbag359 &​ @Abe Chavez Nope, your thinking of a serpentine condenser. This one is a parallel flow condenser. It does snake down but typically in multiple rows at a time. Pretty much all cars have used them for over 20 years.

[@Theezmoney]

yes i have seen another video where it showed if the lines were not cold around the low side around the drier but check the line at the bottom of condenser and if it's cold there then the condenser is clogged. I don't get any cold lines anywhere but a shop told me they thought i had a clogged condenser. But when i took the orifice tube out of the line going into the evaporator it was cover in black gunk and oil. So wouldn't be more likely that the evaporator is clogged instead of condenser. Or maybe will it work just by changing the orifice tube which i have but haven't tried to charge it yet.

[@thejflores1219]

Great video how always love watching them. But to help you out on how the AC or refrigerant system works and the gas entering the compressor is gas and a little cooler but when it leaves the compressor is high-pressure and still a gas. As compressors or pumps work the internal friction of the mechanical parts as well as the fluid creates a lot of heat.The condenser is in use to cool down the refrigerant into a liquid but still maintain the same pressure from there it goes into the thermal expansion valve. As far as I know there is no compressor that does both gas and liquid. Compressible fluids and incompressible fluids don’t do well in any system. Like a hydraulic locked engine.

[@spelunkerd]

Of course you're correct that only gas exits the compressor, and I share your appreciation of this interesting video. However to clarify your correction, the temp spike of the compressor discharge line comes from compression of the gas into a smaller volume, not from "friction of mechanical parts as well as the fluid...". Examples of that kind of adiabatic temperature change caused simply by changes in pressure are everywhere on our planet, and it is fundamental to how all heat pumps work. Further downstream inside the condenser, the hot, high pressure gas is cooled to ambient temp by flowing air. Cooling of that hot gas inside the condenser allows the refrigerant to return to its natural state as a room temperature liquid at that pressure.

[@unclecowboy2003]

@@spelunkerd thank you for sharing this information I’m dealing with a compressor replacement on an 03 SSR the old compressor seized so I’m sure there’s contamination throughout the system I can’t find an orficetube but it has a expansion valve I also can’t find a reciver dryer so I’m stumped I vacuumed it out and proceeded to recharge it and it will not cycle the compressor it’s pressure is equalized at about a hundred psi maybe thinking of jumping the electro magnet to engage the clutch and see if it will work hopefully the compressor isn’t wired incorrectly they painted the wires so I’m yet to know if that’s the case any help would be greatly appreciated

[@topher8634]

@@unclecowboy2003 I recommend replacing the condenser if the compressor was mechanically seized. If just the pulley and clutch you could probably get away without replacement. The condenser on those vehicles is call a Micro Channel Heat Exchanger or MCHE. It cannot be flushed of debris. If you have an expansion valve then you won't have an orifice tube. It's one or the other, unless on a vehicle with front and rear systems then it's possible le the front will have a TXV and the rear have an orifice tube or vice versa. On TXV systems you should have a receiver and it may be part of the condenser. On orifice tube systems you will have an accumulator between the compressor and evaporator on the low side (suction) line. If the compressor clutch doesn't engage with A/C on, first I would check for 12 volts at the compressor clutch connector. If present then you have a bad clutch coil. If not then check pressure switches (low and high) some vehicles only have one. If yours has 3 wires then it is probably the only pressure switch. Also check the A/C clutch relay and of course fuses. I have on rare occasions seen the control panel fail and not turn on the clutch. Hope this helps.

[@trojangpete8]

In this video what did you have your yellow line connected to?? How did it not loose pressure from the yellow line?

[@yomomma9070]

Also, was curious. Were is the high press cutout? Was it jumpered? The blow off is a last resort fail safe to keep something from exploding. Usually the high press switch is in the hot gas line between comp and cond. If not jumpered, or missing, you might want to replace it.

[@ADVANCEDLEVELAUTO]

The high pressure cutoff switch is located after the high side port. Much like we don't see the extreme pressure on the gauge, the switch does not see it either.

[@yomomma9070]

Was thinking it may be after it, haven't had the opportunity to work on the Odyssey yet. They should've installed in the discharge line between the comp and cond. That was a design flaw in my opinion.

System was overcharged by me trying to solve the problem with a Wal-Mart can and gauge . No luck. I guessed there was a blockage in the condenser so dismounted it , bought a small fluid pressurizable tank at NAPA and some stuff I think was called Dura flush . Its mostly pentane so flammable . I put it in freezer for an hour before starting . Pressure fed the Dura flush into the condenser discharge side at 90psi . Nothing happened for about two minutes so hit it again with more . All of a sudden whoosh and a gusher of gunk shot and spattered about 20 feet across my driveway . Glad I had on safety glasses . I flushed the lines to and from the compressor too . After new o-rings and assembly with an ounce of AC oil added to the condenser , 30 minute full vacuum and recharge with 134-a ( had already replaced TXV and STV POA ( car has rear evaporator , too ) I got 44F at vents with fan blowing on condenser, 2000 rpm fast idle on 92F summer day . Now get 225 psi on high side at 75F .

I'm having the same problem. After recharging with fresh refrigerant started shooting refrigerant from compressor. I suspected that problem is in the high side. The low side lines become ice ,but strangely it shoots refrigerant from compressor. So I think the high side is being blocked. And I did change the orifice before. So I don't think the orifice I clogged.
