: Climate Control Issue 88 Brougham

06-20-11, 06:40 PM
So the other day I fire up my 88 RWD 5.0 L Brougham and notice something quite peculiar with the Electronic Climate Control. The AUTO, HI, windshield defroster, rear window defroster, outside temp, warmer, and cooler buttons all work just fine. However, the OFF, ECON, and LO buttons do not work, and they do not warrant a response when pressed. Thus I am stuck with my A/C on when I start the car.

I at first thought something might be wrong with the buttons so I cleaned them with some WD-40 to no avail, and to try and shut off the A/C I did a reset but unplugging the battery for 10 minutes again to no avail.

I have also really worked the buttons hoping to loosen them up again to no avail.

Since the majority of the buttons work, I have ruled out a busted fuse [I checked anyways and sure enough the fuse was fine].

Has anyone else had this problem, and does anyone have a suggestion on how to fix it? Thanks.
