I have searched the forums with a couple of ideas of what is the problem. When I turn on the AC the light starts to blink after the AC compressor engages and turns off almost immediately. The compressor is not seized from what I can tell when I turn it manually with the engine off. Any ideas? Thanks.

 

Bump....bump....

 

most likely you are running low on refrigerant. or have a leak in you setup. It did the same for me when my AC hose ruptured.

 

Was your pressure low in the system?

 

Bump. Bump

 

With the car off, hold down the AUTO (Fresh / recirc) button, then turn the ignition on. Hold it down for a few seconds more, all the lights should blink on 4 times. When you let go of the button, it will display the trouble codes, use the drivers side temp control to cycle through the codes.

Post up the codes that it displays!

 

y the bump bump?ricky told you, you probably have a leak or low freon. go to a mechanic and have them put their gauges on this will tell you your pressures which MOST of the time can help you figure out what it is

 

I put some gauges on it today and it does not have a leak. I think the belt tensioner might be bad causing the belt to slip and cause the AC to kick off along with a temp loss of power steering and alternator charge.

 

you did huh? what were the pressures?

 

My neighbor put on a full set of pressure guages to test the system for leaks. I do not recall what the pressures were but they held fine and the system as far as he knows is leak free and running properly. He is a A/C guy by trade so he knows more than I do about the system. But now I think that I do not have a seized AC compressor but rather the crankshaft pulley needs replacing. I started the car Sunday and the belt started to smoke, after turning off the car I looked at the belt which was intact but looked like it was not quite on a pulley corretly (It was it turns out). I was taking off the belt and a piece of the crankshaft pulley fell off. Now I'm calling around for that part and see if that fixes all the AC issues due to the old one seizing or something.

 

i manage a HVAC supply house so im a/c guy by trade also and thats why im asking bout the pressures....

 

I'll ask my neighbor what the pressures were. Thanks for the help!

 

Has it been raining a lot where you are? I had this happen and it meant that the system detected a slip in the clutch for the AC compressor and it just does that until it dries off. I have also heard that some older models required replacing a relay for the AC unit to fix the issue. Let me know what the weather has been like.

My ac light started blinkin ac stopped blowing cold and then the ac compressor starting squealing really loud. And ideas?

 

It blinks to let you know that it turned itself off (usually as a safety precaution) because the clutch is slipping (Air conditioning clutch)... If it got wet and slipped then it would turn itself off and blink until you restart the car and it is dry and the AC clutch does not encounter any more slipping.

WOW SORRY, I didn't realize how old this thread was lol... Sorry to bring it back so late
