ac stop working all of a sudden, believe the compressor wont start because rpm stays constant when turning on AC... Ac light comes on, wind comes in from the fan but no cold air. What can go wrong electronically with AC?

 

Did you check to see if you have freon in the system?

 

well, i just refilled it a month ago, but i beleive freon only makes it cold, but shouldnt the ac unit still be runnning, with or without freon?

 

Dunno. My AC doesn't work either, so I took it out. Now the engine is more free-revving.

 

it wont run if u dont have freon, if u got it refiled last month, go back and ask them to check the pressure. You might have a leak somewhere.

 

The AC system is a CLOSED system, you don't "refill" it, it's completely sealed.

Sounds like the compressor is shot.

 

so time for a new compressor?

 

yep.. sounds like your compressor is broken... if you were out of freon, which you shouldnt be, unless you have a leak, then your ac would still blow out, but it wouldnt be cool air.

if there is no change in the rpm's when you turn it on then the compressor is prolly not engaging... it could be the compressor but if im not mistaken there is an ac switch or relay that could be faulty.

The Ac can leak out

It sounds like you are low on pressure. The same thing happened with my GF. Bought a top up kit from autozone for $20 and works fine.

 

top up kit?? to what? seal any leaks?

 

The system may not have a small leak, however if it is not cycled often the freon can lose its charge.

A top up kit basically does as it says-replenishes lost freon, you attach it to the low pressure connector and follow the directions. For $20 its worth a try. It may take a few secondes but the compressor will kick on.

 

the molecules are tiny enough they can escape out tiny pores in the ac lines....thats how you lose charge

 

will the condensor fan turn on even without freon? Cause right now my condensor fan on the radiator dosnt even engage.

 

im selling all of my a/c if you need any parts. compressor, lines, etc..

yes, the only reason you should have to refill it is if it has a leak. in wisconsin its illegal to attempt to fix your ac system without being state certified.
