hi - the display of my ac/heating module does not light up -I reseated the fuse & the display came back for a few days - although the fuse was good, I replaced it anyways, but the display is still off - all the controls work - any suggestions? thanks

i had the same thing happen to me , you have to replace the a/c heating insert . poor printed cicuit on the back, peice of cake-- junkyard part ooops recycled part , good luck

I agree that the pc board is probably bad. You may want to try to hunt down the bad soldering joint(s) and try to re-solder it/them.

Thanks for that info on the fix. Mine is currently out as well. I'll have to look into that.
