I have a 93 850 glt sedan with electronic climate control. The Climate control unit in the center console does not work; I can't even make the fan operate. It will illuminate when I turn on the lights but that's about it. I recharged the A/C and replaced the climate control relay behind the glove box but still no luck. The previous owner's mechanic told me that that would fix it and that there was some type of grounding problem. The fan is new so that's not the problem either. The dealership wants at a minimum estimate, $2-300 bucks just to trace the problem but who knows if they can even do that. Has this happened to anyone else before and/or does anyone have any suggestions? I'm starting to pull my hair out with no A/C in the summer in Hawaii! Thanks everyone!
