Air Con - Testing Compressor Switched Supply
Posted: Sat Apr 24, 2010 9:44 pm
Hi Folks, sorry to raise the dreaded "air con not working" topic again as clearly there has already been much debate & data...however - Ive followed all the info I can see so far (belts/10A fuse/obvious connections etc) but to no avail.
My problem is that the fans blow on all settings, the heater linkages are all in place etc, I get full normal heater controls but no air-con, when I press the air con button the compressor doesn't switch on - I have looked for the switched supply to the compressor clutch and can only see one small black wire attached to the front of the compressor its self - Ive put a meter across this and its dead in all states - I'm assuming this is the feed to the clutch and therefore expecting the clutch to actuate with a 12v feed.
Can anyone help and advise how this feed can be tested to rule out the compressor or clutch being failed - can I simply put 12v to the clutch via this wire?
Thanks
