    93 deville A/C Compressor Clutch Relay... Where???

    Where is the A/C compressor clutch relay for a 93 deville. I was thinking on the firewall or behind the glove box. Can someone give me the specific spot of one of those location?

    On my Tech II it shows the computer is sending an engage command to the A/c clutch but the compressor is not running. First thing is to check for voltage at the connector I know but I'm hoping to find some info on where the relay is before I get started so I don't get stuck.

    I just evacuated the refrigerant and refilled enough refrigerant to not trigger the low pressure switch. Removed battery cables and still cannot get the clutch to engaged to finish the charging process.

    thinking possibly bad relay or clutch. on the dryer I completed the circut for the switch and still no clutch.

    Thanks.

    You need some special tools to remove and install the clutch.

    Where it is, I don't know. I was trying to find a solution to dropping the column on my '93 to replace the dimmer switch for the headlamps and saw your post. I had a similar prob.

    After clearing the codes, mine would not kick in until I got the engine RPM up over fifteen hundred to maybe two thousand or twenty-five hundred RPM. My mechanic and I just brought the engine RPM up slowly and let it race. Then -- KLAK! The SOB kicked in and I was able to finish the charge. Killer was, after it took the charge, we had to race the engine to get the A/C to kick in again. Now it works normally. *shrug* It's a Caddy. Expect the unexpected.
    You might give that a try first.

    Wendy.
