Engage AC Compressor Clutch with a Paperclip on Relay | How to Fix Bypass Won't Engage | Jump Relay

If your A/C compressor clutch won't engage because the refrigerant is too low, then you can jump the 30 and 87 pins to get the Clutch Engage. Make sure you are prepared to immediately fill the refrigerant, or shut off the engine and prepare after seeing this works to engage the AC clutch. Because you do not want to damage the compressor by turning it on too long without Refrigerant.

Believe it or not, In most dealship workshop manuals this is step #2 in troubleshooting the ac compressor.

Great Advice... I didn't know what was wrong with AC system. This technique allowed me to get the Clutch engaged.

So I have a 2006 dodge grand caravan, have not had ac in years (my teenagers were driving so I didn't care if it had air lol) But now I'm driving it and it's getting hot out.. All the refrigerant had leaked out due to the notorious rear leak. So I capped the rear lines (very easy). I proceeded to put refrigerant in but the ac clutch did not engage (I thought bad compressor due to not being used in so long. Did a little more research and read it would not engage if refrigerant was empty so I jumped the relay (30 to 87) and the compressor came on! Filled it up with 3 12oz cans and now works great! Thank you for the video!

[@redcloud5813]

That's encouraging. I also have a '06 Dodge Grand Caravan. I kept hearing a loud grinding noise that was coming from the engine bay, only at idle. It did it for years and a mechanic told me it was the alternator when he I had it in the shop to have the rack and pinion replaced. The noise kept getting worse and I determined that it was coming from the AC compressor by removing the AC clutch relay fuse because the noise stopped. I replaced the clutch, pulley and coil. The noise went away, but the clutch will not engage. The AC had stopped working sometime since last summer, but I thought it was related to the clutch noise. I tried adding refrigerant, but the clutch won't engage and it shows about 80-100 pounds static pressure on the low side. I also tried replacing the pressure (transducer) switch since it was only $12. Hoping if I can get the clutch to engage I can troubleshoot some more.

I don't think A/C relay "knows" if you are low on refrigerant. It simply sends electric current to the A/C clutch. That's all it does. Another component called "the refrigerant pressure switch" can prevent clutch from engaging if you are low on refrigerant. It would have to be bypassed in order to charge the system. That is the real "chicken and the egg" situation....

On a lot of cars the A/C pressure switch is on top of the A/C receiver-drier (vertically mounted cylinder often in front of the A/C condenser/radiator).

Hello there, I have a ford explorer car from 2010, when I turn on the A/C the clutch is not working, when I remove the relay as what you said the clutch works just fine. I checked up on the lines and nothing was in a problematic order.However, I got to discover that the negative line that turns on the relay is the one that gets lossed when the A/C is turned on while the relay is on its place and when I connect a negative line directly to the battery to the relay it can work just fine so I connected it directly but the clutch works always.i would keep that for granted if I got a reply on my question. Greetings.

[@soburnedout]

This works because it is the pcm or ecm (your car’s computer) that would normally provide ground to the relay, completing the circuit. The computer will only do this after verifying certain conditions are met by reading voltages provided by the various sensors. If satisfied, ground is provided electronically, the relay closes, and …you know the rest. This procedure should be done ONLY to get your system to accept the r134, and IMMEDIATELY restored to its original configuration, with the relay in place. If the relay is bad, swap with another like the horn relay until you get another one. Typically there are many of the same relays used in a vehicle. Just be sure to get things back to the intended order before something is destroyed- being that your post is a month old, I hope it’s not too late…

Before jumping any connectors in the junction / fuse box bypassing a relay or fuse you must be sure of what you are doing. You likely blew a fuse, but putting twelve volts into the computer control side of a switching circuit ; a relay, which is only 5 volts you can dammage your vehicles "brain"; $$ & more $! There's a few good videos on U Tube explaining how relays & fuses work & how they can be safely tested & bypased. kzbin.info/www/bejne/Y2XSdHSbod-lja8 Start here ; kzbin.info/www/bejne/fZiVYYtje9x6sMk

Updates?

I have a 2005 Pontiac Grand Am. Refrigerant level is good has no leaks. Put a new AC Compressor but still don't have Cold air. AC Compressor doesn't active. What can I check??

[@MrPaknight]

Relay and fuses.

[@MrPaknight]

Check voltage at the plug should be 12v. With the key on of course.

[@zu1502]

What does it mean when it works when I jump it and it doesn't when I put the relay on ? The relay is bad? Also when I jump it the lines get frozen ice

[@aconformist1]

check refrigerant levels when compressor is jumped. could be low refrigerant. The compressor clutch wont run even if the relay is good if there is not enough refrigerant

[@rjaymontanez]

Do u leave the paper clip there

[@26bleeek]

It worked when I 1st did the bypass but now my ac compressor clutch don't work at all. Idk what happen. When I touch the 2 connections nothing happens.
