My A/C compressor won't ever turn off...
So, I always thought that the A/C compressor was supposed to be off in Econ mode or when the system is off. The clutch for mine is always engaged no matter what setting I have it on or what the temperature is.
Any ideas?

Bad relay or short somewhere?
I know when I have switched my cars from r12 to 134a the comp would not cycle on and off when I had the ac on... But for the comp to stay engaged even when in the off position that's strange

I hadn't thought to check relays. I just have noticed it making it's gurgling noise even when I don't have it turned on.

Re: My A/C compressor won't ever turn off...
Is the clutch engaged when the engine is not running?
Btw, the stock SVX system will not cycle at all unless a protection limit is reached. The compressor has a variable discharged feature. Tapani |

Unplug the connector from the A/C compressor and then start it up and see if is still running. If so the clutch is dead. If not it is an electrical issue somewhere.

Re: My A/C compressor won't ever turn off...
Correct. There is a plug, which, if you follow the wire, goes to the very front of the AC compressor near the clutch, that if you unplug will disconnect the power used to activate the AC clutch to grab the pulley. That will determine whether it's an electrical issue or a mechanical one at least.

Re: My A/C compressor won't ever turn off...
The clutch is good, so I know its an electrical issue. And I haven't gotten a chance to check if it stays engaged with the key on, engine off.
I'm hoping it's something simple like a stuck relay... Just gotta find the time to track it down!

Re: My A/C compressor won't ever turn off...
That was the easiest fix ever.
Here's what I did: 1. Swap relay with high beam relay 2. turn key to "on" and observe high beams stay on with switch in low beam position 3. Pop plastic cover off bad relay 4. use small screwdriver to free stuck contact plate from coil 5. reinstall relay Tada!

Yep, I'm hoping it'll help my mileage a little too... but not too likely.
