AC works fine when driving, but stops blowing cold when stopped. It's an easy fix!!

Just because the control relay seems to be working, doesn't mean it's actually working

Thank you for your kind words. Keep wrenching 🔧

[@user-pu8gm5ey3g]

The problem is obvious. Looking at the top of the relay, you will see the letters “FoMoCo”. That’s it.

@@WrenchingWithKenny I have a question 2011 ford edge A/c works on way to work . Then lunch break drive to store it blows warm . After work driving home A/c works again . What do you think is going on ?? Now I understand it could be many different reasons but looking for easy things I can look at before taking to the shop . Thanks

[@LastTrump7]

@@WrenchingWithKenny​​⁠2011 Ford Fiesta. Air conditioner has always been cold. I replaced the cabin air filter and since then the air condition blows cold as it use too but now fluctuates. Sometimes at a stop and even sometimes going down the highway at 60 mph. It can be 5-15 mins apart or longer?..

[@tannersloan7]

This fixed my a/c problem! Thank you. My car was only getting cool air when driving on the highway. I originally thought it was low on refrigerant and bought a recharge kit, hooked up the gauge, and found out the pressure was in the green. After about two hours of research I came across your video. I have a 2014 Ford Explorer, so I switch out #98 “Air conditioning clutch relay” with the #77 “Trailer tow park lamps relay” relay switch (same type).

Found that similar issue with AC clutch engagement on Hondas, relay would click but wouldn’t turn on compressor clutch

[@godschild138]

I gotta Honda Accord

[@Ray956Texas]

So one thing I always do is swap out relays within that fuse box . For example the horn or ac blower fan in the dashboard relay will have the same oem part number as the for example radiator fans. I'll 1st verify the horn is working that tells me that rely is good then swap it out with the radiator fan relay and now see if the horn sounds . If it were the ac blower fan in the dash verify the blower is blowing out the vents then swap and see if the blower still comes on.

[@wbien6994]

What happens to the contacts from arcing over and over they get a jagged surface and not enough of the contact is touching to pass enough current. Also sometimes the surface is so pitted they get hooked and won't release.

[@DCherbonnier]

If the fan is not coming on due to bad contacts how does the engine speed affect it? I thought once relay contacts are corroded or other wise defective they could not pass current. I have the situation where the AC works when driving, and the engine rpm's are above idle, but when the engine is idling the compressor shuts off and it stops blowing cold. As in the title of the video. The video totally did not address that issue.

Snap on rep got you on the new pliers too I see

[@skrypture1162]

😂

[@joenunya8449]

@wrenchingwithkenny You could cut the cover off the failed relay and bench test it for demonstration purposes. It has a magnetic solenoid that pulls the contacts together. For this failure mode, the solenoid works but at least one of the contacts have failed. Relays can have multiple contact pairs. You can test this electricaly by using a DVM in resistance mode across the the matching contacts. It should go to 0 ohms when the switch actuates if it is working correctly. You can actuate on a bench by applying 12v and ground to the coil contacts.

[@slimsherman5818]

Yeah with my 05 Caravan i switched out the fan relay with the horn relay, unfortunately that didn't do the trick. So all the a/c fuses and relays look good, I will now see if I can find my 10 guage wire clips and hook up directly from battery to fan itself to test, because i believe the fans are shot

[@cowpuncher2005]

Have you ever encountered this? 2014 Silverdo blows hot air when ac is on and motor cooling fans start blowing maximum. Turn off AC and cooling fans slow down.

[@ThePrivers241fan]

Where are you located? I need someone to teach me where those relays are but I'm sure you're not in Melbourne Florida. They keep trying to tell me it's my AC fan if it could be an easy fix like this you rock! My ex was mechanic my ex before him and my father growing up why can't I get away from you guys LOL but that was one good thing about having him around them but they were all bad guys so I want to know how to get this fan going before I drive off because driving it blows out cold sitting it's blowing out hot if it's just the relay switch and out of $500 fan you're the man! But I still want to know how to get that fan moving before I drive off they did it at jiffy lube but I don't remember how I can't find it on KZbin maybe you can help me out. Blessings. Pixie 😅

[@Fullhouse0056y6]

What fan are we talking about? Big radiator fan(s) or fan inside of car that you control from inside?

[@user-mo2oo6gy9x]

Thank you! I'm checking that right now.

[@imwaytogoodlookingtobeyour1188]

I have a 2017 challenger and the a day before the ac blew very cold air from all vents....the following day it just started blowing very warm air and I have it set to 60....and that's because I rarely even use the cold ac

[@quiter75]

Anyone know where that part is on a 2016 Nissan Versa

[@alfredocuomo1546]

It is not uncommon that a relay fuses it's contacts together or they become extremely pitted, in the old days we would take it apart and run a Burnishing blade between the contacts to clean & polish them up. But we now are in the throw away zone today.

Could be that the cooling fans aren't working. The ac may not be commanding the fan, the fan control might not be working. Could be a wiring issue. I really can't give you anymore info without having access to the car. I hope the info helps. Thanks for watching 🔧

The cooling fan may not be working when it's supposed to so the pressure builds up which might be the squeak. It's hard to say with out looking at it though. Sorry I couldn't be of more help. Thanks for watching 🔧

[@joenunya8449]

Many cars have two cool8ng fans. One for the radiator and one for the ac. The ac fan may have failed and when the car is warm the radiator fan comes on and keeps the ac partly cool. The ac fan normally runs constantly when ac is on for most cars with electric fans.
