A/C compressor shot?


Recommended Posts

Posted

Well, I think my ac compressor may have finally given up the goat today... In the past it hasn't been engaging, and so I could turn the car off and back on and that would usually fix it.. Today though, it just will not engage for anything... The pulley part of it is turning, but the part outside the belt is not turning when the compressor is turned on like it used to. I was wondering if it was sounding more like a compressor problem, or an HVAC control problem...

problem = low R134a most likely.

 

Will it hurt it to run the compressor (for defrost setting) with low 134?

you beat me to it thats what i was going to say and as for the compressor its not turning on anyway so how could you hurt it

As long as the compressor is oiled well it shouldn't hurt - but the defrost won't work properly without the compressor running anyway - A/C dries the moisture from the outside air

So I need to recharge the ac before my defrost will work? Also, how do I check/oil the compressor?

yeah. a non working compressor hurts nothing. except defrost and a/c.

 

you probably don't need any oil, just a re-charge of R134a.

Alright, I guess I'll pick up one of those recharge kits next time I go to the parts store (provided they still have them), because my defrost has to work... Is it very hard to do?

Air will still come out of the defrost vents on the dash but it won't be as effective as it should be without the a/c system working properly.
