Thanks Tom,


The A/C is always on since we've top it up recently, but the A/C switch and
light, and the Recirc switch and light are both off.  Could it also be the
relay sticking? I will be looking at it later today.

I assume we're talking about the manual climate control here... Are the
indicator lights in the A/C, Recirc switches on regardless of the switch

If the lights are always on, you're probably dealing with a bad switch. If
the lights go on/off as you turn the A/C switch on/off, you're probably
dealing with  either a bad switch or a bad A/C clutch control module.

I don't see any humidity sensors or anything else in the wiring diagrams in
my Bentley manual. The only other switches in the system are the pressure
switches to control when the A/C compressor turns on/off. But the main A/C
switch should override those.

My wife's 93 90Q's A/C is always on, even when the A/C and recirc buttons
are turned off.  Has anyone experienced this before?
