A38 psi if on the high side is not suffient. It should be from 90 to 130 psi. You must be using an auto parts store refill kit that has a guage attached to it. If so, you need to try another can. If not, you should refer the problem to a qualifed ac mechanic.Also, if you notice that the ac clutch is cycling on and off with in 10 seconds, this indicates that the systemis loww on freon.

Ac clutch relay 2001 lincoln ls location

Ac not working


Might be your AC clutch isn't kicking in(actuating).OR you might not have enough refrigerant in the system to tell the low-pressure cut-off to actuate the clutch.
Staying clear of the engine with any loose clothing, look down at the AC compressor while someone starts the engine and turns the dial from OFF to MAX air and you should be able to see the pulley end of the compressor grab and start pumping.
If it doesn't,it could need more refrigerant,but more likely it is a blown AC fuse or circuit breaker.There is sometimes a row of relays in a box in the engine compartment.They occasionally need replaced just like a fuse. don-ohio (:^)

I have a 2003 toyota corolla. My AC would blow cold air for a min or two then when the compressor shut off it would no longer blow cold air or come back on. A new compressor was put in it but it did not...


the ac clutch relay is the problem. It is located in the under hood fuse box. It is a $10 part. The relay will make a clicking sound when activated but the contacts inside are burnt causing no electrical flow to the ac compressor. Simply unplug and replace. The relay is labeled M/G CLT .

replace or blow out the cabin air filter as well. It is located behind the glove box. Instructions are in your owners manual.

The ac in my 2006 dodge 2500 gas engined truck does not blow cold when the engine is at idle. when running normal speeds the air gets cold


start by cleaning or replacing your in cabin air filter. check to see if your AC condenser fan is turning when the AC is turned on. Make sure the front of the radiator is not clogged with bugs, mud, etc. Check AC compressor relay-make sure the compressor clutch is turning the compressor with engine at idle. lastly check for proper refrigerant charge.

Car overheating and ac is hot and have 0645 code


There is an electrically driven clutch on the front of the air conditioning compressor which engages when air conditioning is required The AC compressor has a fan belt driven wheel on the front of it. The belt turns this wheel all the time. When the a/c is off this wheel spins freely. When a/c is required the electrically driven clutch engages this spinning wheel to supply drive to the a/c compressor shaft. The 0645 code concerns a fault with this clutch.

My 2002 Expedition air conditioner will sometimes blow hot air and others cold air


I would check the following possibilities:
1. Is compressor clutch working? - You need to do this when the ac is blowing hot air only - locate compressor drive pulley on engine - rubber belt wraps around it. Start engine and set to max ac. When the ac is blowing hot air, look at the center of the compressor drive pulley using a good flash light - watch it for a while, it should be spinning with the pulley - this means the compressor is engaged. If not, the compressor is not engaged. If your ac is blowing hot air, then the compressor should be engaged and running (trying to cool). If it is not engaged, then your compressor clutch is probably going out. Could be low voltage to clutch, but more likely the clutch is worn out and only working some of the time. Note: if working normally, the compressor clutch will engage and disengage in cycles- but the air should always be cold. If clutch is bad, compressor would need to be replaced (sold as one unit). This is tricky to diagnose and could take some time - you need to do it when ac is blowing hot air but set to max cooling.

2. Low on refrigerant or refrigerant has moisture in it? If your ac blows cold initially after being off for a while, then heats up, and continues to regularly cycle back and forth between hot and cool air, then the system may be low on refrigerant or the refrigerant may have moisture in it that is freezing and restricting refrigerant flow. An a/c shop can check refrigerant level and even replace refrigerant if moisture is suspected.

Could be other issues, but I would start with these.

Good luck

AC was blowing cold. Now only warm air comes out.


May just need to be recharged, if r34 is too low, ac will not kick in, Wal-mart sells recharge kits and cans of r34 (insctructions are on kit)...expect to pay around $50 total if you do it yourself. If that doesn't work you may have to replace the AC compressor.
