Hi Everyone,

Another AC problem......

Like everyone else with AC problems, my AC also runs cold to hot, cold to hot. RIDICULOUS!!! Now I have a new problem. Today I was running my AC. It was nice and cold until it ran about 30 minutes then it went warm. At this time I saw smoke coming from under my hood on the passenger's side. I stopped the car and got out to see what the problem might be. The smoke was coming from the bottom of the belt on the left side. A man walking by told me the flywheel to the AC unit was sticking/skipping. I could see this happening. It would turn then stop, turn then stop. I thought it was the belt but he said the belt was fine.

Does this make sense to anybody becacuse I have no idea what a flywheel is. I saw it but don't know what it is. Anybody know how I can stop it from skipping or sticking? Did I run out of freon or is this a much worse problem? Please HELP????? I hate to take it to the mechanic without any knowledge of the problem. If I do they'll tell me they have to replace the whole AC unit. Any info anyone out there would give to me will be GREATLY APPRECIATED!!!! Thanks for your time in replying!!!!

Laurie

Laurie,
The "skipping" is the compressor which engages a clutch (what you see turning) to push the r134a down the line. The "smoke" should have been white, the r134a is super cold gas and causes the water in the air to cool down to make a cloud. The rapid cycling of the ac clutch is normal for a system with only a little r134a left in it.
Take it to a radiator/ac shop to get it fixed. They have the black lights to see the leak after dye is added to the system.

The "smoke" was probably ac coolant escaping from a major leak. Once the coolant pressure drops due to the leak the ac compressor pulley clutch will start turning off and on every few seconds. This is probably the "flywheel" the man was talking about. You've got to take it to a good ac shop and have them id the leak, replace the defective part and recharge the system. This is going to be $300-400 or more depending on the part. You may be able to id the leak by adding some coolant yourself. If it's one of your compressor hoses you may as well have them replace both at the same time.

Hi Fixit2003:

Thanks very much for the info!

If there were a major leak, wouldn't I have seen some fluid on the ground? There was no fluid at all leaking from under my car. Also, can I use that dye stuff first to see if I can see a leak?

So, if there is no coolant, the flywheel will stick? There's nothing wrong with that part then?

Thanks, again!! I appreciate it!!

Laurie

When the system leaks it is a gas not a liquid. Yes it is a liquid when compressed. What does the "smoke" smell like? electric? rubber?

Hi Jot,

Sorry I never got back to you! My computer was done for awhile and I was on vacation for a couple of weeks. Thank you for your reply to my question about the smoke coming from my compressor. I now have a new problem and hope you can give me some info......

The problem was my compressor and it needed to be replaced. My husband just had open-heart surgery awhile ago and right now our money is tight!!! I could not afford a new compressor ($762.82) so I went to a very well known used parts store in my area and bought an 850 air compressor. It had been tested and worked great. I brought the compressor to my mechanic and he installed it for me. He also said the compressor worked great. The problem is that the car is not blowing any cold air at all. My mechanic put in one pound of R134A. Is this enough? What could be wrong here? Both the parts store and the mechanic say the compressor works great so why can't I get any cold air from the AC?

ANY help you would give me on this problem will be greatly appreciated!! I just don't know what to do here. I can return the compressor but, if it works, I'd like to keep it and find out if there's something else that needs to be done here. If you could send me some info on what to do I'd be so happy!! The mechanic just couldn't figure it out and didn't want to keep it for hours and have to charge me labor. I told him I could contact this board and hopefully get some answer to this problem. HELP!!!!!

Thank you very much for any help you would give to me!!!

Laurie
