A/C compressor not engaging.
Is there anything other than a blown fuse or relay that would prevent the A/C from turning on?...it appears my compressor is not engaging. Fans and other climate controls work fine but the ac does not. Will low pressure in refrigerator lines cause this? I don't wanna spend 30 bucks on a recharge if I don't have to..

Re: A/C compressor not engaging.
It will...
It is a safety feature to keep the compressor from sucking moist air and other contaminants in the system if a leak develops and the refrigerant is lost. Keith |

Re: A/C compressor not engaging.
Low pressure will cause compressor not to engage due to low pressure cutout switch. You will want to recharge with a dye for finding leaks, if this is the case...

Re: A/C compressor not engaging.
I just had a similar problem with my '96 SVX. The cause was a rear seal on the compressor had failed, and the refrgerant had leaked out. Couldn't even turn the compressor by hand with the engine shut off.

Re: A/C compressor not engaging.
forgive this dumb question but would the Climate control diagnostic module tell you what the problem is?

Re: A/C compressor not engaging.
Maybe, it depends what the problem is??? It won't give an error for high or low pressure in the system.

Re: A/C compressor not engaging.
When I tried pulling codes on my '97 when I knew the refrigerant pressure was too low because it had leaked out, it didn't show any codes. 2 O-rings and a recharge and it was all fixed.
