a/c just comes on by it's self...?
Posted 05 August 2003 - 02:41 PM
Last winter, when the heater was on the floor or defrost mode, it would just change to the bi-level mode by it's self. It's a little annoying when you are trying to defrost the windshield.
I think the two are related, but I don't know where to start looking for the problem.
Any help on this one is much appreciated.

The idea is that the A/C will dry the air being directed towards the windshield.
This happens in my 95 Legacy, and it also happened in the Peugeot we leased during our last Europe trip.

No one has been into the dash since I've owned it, (2 yrs) and the a/c etc; has always worked fine, then last winter, the bilevel comes on when I need defrost, sometime later it goes back to defrost and then back to bilevel without warning.
However, I did take the dash apart yesterday. I pushed the off button and the whole switch assy just pushed back into the dash and nothing would work.
I removed the off button and the mounting screw came loose and backed out resulting in not being able to push the off button in, and of course the top screw/bracket broke as well.
I fixed it by installed an oversized screw on the bottom used a "spacer of sort" to hold the top of the assy. Now everythings works nicely, except if I have the switches in any position but off, the a/c will just come on by it's self after a while.
I remain puzzled, but at least I can push the off button in now.

Next the ac is triggered by a microswitch which is located above and toward the center of the car from the gas pedal. (Under a small cover has to blue wires running to it. When ac is called for a lever closes this switch. Might disconnect this (follow wires to the plug) this will prove it is a mechanical not electrical problem.
I have disconnected the micro switch and connected it to a rocker switch on the dash. It is
mounted in the blank beside the fan speed knob.
email me if further assiatane is desired.
Hope this helps
