Sounds too me you have Low refergerant level in system there is a pressure/level switch in system that cycles compressor on/off to see if pressure/level will come back up , No it shuts off and tries again in a little bit , not too good on compessor to do this too it , it's not circulating its needed lube and it'll dry out
if your car is made in last 15 yrs they sell a recharge kit at autoparts store so easy my 12 yr old neighbor did it to his moms car costs less than twenty bucks to get you going, provided you did'nt ruin any parts running it low too long

SOURCE: Air conditioner won't stay on.

'64 could be right, but these Malibu's also have a tendency to go through HVAC head control units, among other things. I have taken the head unit out of mine and cleaned the contacts, etc...with some success. However, from what I've seen, this is just a temporary fix. These units run upwards of $200 at a dealer, but you can get one online for just over $100. It is a really easy install.

Other common problems include:
-Cruise control modules going bad (cruise kicks off at will)
-Bad resistor on fan blower (only speeds 3-5 will work)
-Front coil springs breaking
-Front brakes wear funny, excessive wear
-Moisture in headlight housings

SOURCE: ac clutch

sounds like the system is either low or out of refrigerant. There is a low pressure switch in the system to shut it down in the event of freon loss. First , verify , then test for a freon leak. Once repaired, and recharged, will blow cold air again.

SOURCE: 2001 dodge ram 1500 ac is blowing hot air instead of cold

Your A/C sounds like it needs to be vacuumed
out and then recharged to factory specs. That
should solve the problem.

My 1986 300e air conditioner works great, then cuts off. I start he car and it works great and ice cold. Then goes warm. Is it freon?


First your ac comp has a clutch. second r 12 and r134 are NOT compatible if you just "add a pound of r134" you will kill your entire ac system. The O rings, dryer and pressure switches are not interchangeable nether are the lubricants and you WILL burn up your ac comp. Just a word or caution. It is probably the ac speed sensor to detect slip.

If this was happening to me.... I'd goto an airconditioning re-gas centre and get them to check for gas leaks. In my old commodore the Evaporator Core was leaking and causing some of the issues you have mentioned.

AC vents on passenger side blowing warm air even though control is set at 70. It doesnt feel like heat, it's probably ambient air. All other vents blow cold air.


You will probably need a new RF temperature actuator which is on top of your HVAC box/under dash pad.($400 + at dealership.) I have replaced MANY....They get stuck and dont know where they are...If you want to try and recalibrate them yourself you can remove the HVAC/ECAS fuse in the underhood fuse block for 30 seconds(engine running) and reinstall the fuse and wait(IMPORTANT) 2 minutes...do not operate the a/c controls during this time...(engine still running) ..Then shut off vehicle and wait 30 seconds.. start the engine again and operate the A/C and see what happens....Hope this helps!!
