tscraps Posted September 28, 2006 Share Posted September 28, 2006 I have lost the heat and a/c in my 92 sc300. The activation/temp. control button doesn't activate the system. I have also lost the display where it shows which vents are active, but the green illuminating light in that sect. of console is still working. I checked th #2 fuse (10) on the inside box that would power that and it was fine. Anyone? Quote Link to comment Share on other sites More sharing options...

tscraps Posted September 29, 2006 Author Share Posted September 29, 2006 i dont quite get whats happening. could you elaborate a bit more? My ac and heat is dead, no display, it just wont turn on at all. It's like whatever powers the whole system isn't working but I checked the fuse for the ac heat and it looks fine. what fuses power the ac heat controls ? Thanks a lot Tim Quote Link to comment Share on other sites More sharing options...
jzz30 Posted September 30, 2006 Share Posted September 30, 2006 there is a climate control unit that is know to go out. im not sure if it causes the lcd to not show. as far as i remember it made my heat on max cold or super hot! Quote Link to comment Share on other sites More sharing options...
mehullica Posted September 30, 2006 Share Posted September 30, 2006 Check your CIG fuse. It powers the A/C display Quote Link to comment Share on other sites More sharing options...
