Compressor still won't fire up
« on: 25 May 2009, 19:28:26 »
Not really investigated properly - but - My aircon compressor still won't fire up - clutch seems to stay still with climate on or off

Checked the electrical connectors, and can't see any obviously blown fuses.

Any ideas? :y

Just to add - this is mainly only a pain because idle is a tad low, and occasionally she hunts...

James - pull plug on a/c compressor.  Put 12v across compressor terminals (observe correct polarity) - you should hear clutch engage with a clunk.  If no clunk clutch breaked.  If clunk look elsewhere.

sorry to hijack your thread, I have the same trouble, the compressor wheel turns freely however when you switch the aircon on it stays still, is there a relay that swithes over when the you switch the aircon on? if so where is it?, just a thought before spending £65 plus for a regas?

All respectable a/c places can measure gas pressure before committing to vac and refill
