Connerf5 Posted August 18, 2015 Report Share Posted August 18, 2015 Beeps when I push the buttons, nothing happens. Obviously more problems than just that but it won't light up or show temp or anything. Link to comment Share on other sites More sharing options...
ucw458 Posted August 18, 2015 Report Share Posted August 18, 2015 Could be a bad HVAC computer or display. It could also be the light controller for the HVAC display. To the left of the glove box behind the dask you will find a black box with 8 wires on the connector iirc. It's labeled light controller. That controls the dimmer function for the HVAC display. I have seen a few go bad. But check the simple stuff first like fuses and grounds. Link to comment Share on other sites More sharing options...

mechengrkj Posted August 18, 2015 Report Share Posted August 18, 2015 I had this problem before and it was just that the light bulbs were burned out. Couldn't see anything on the display unless you had a bulb in there. Link to comment Share on other sites More sharing options...
techboy Posted August 18, 2015 Report Share Posted August 18, 2015 Is the blower motor kicking in? Are you getting air movement? If it's functioning, I'd say just bulbs like ^^^ said, if it's not functioning though, then you got some other issues. Check the things already listed.

vbrad511 Posted August 19, 2015 Report Share Posted August 19, 2015 My 88 did this when I first got it. Turned out the dimmer was bad (round jobber by your left knee. Changed it, all's been fine since. Do your dash lights work? Link to comment Share on other sites More sharing options...
Connerf5 Posted August 20, 2015 Author Report Share Posted August 20, 2015 Dash lights do work. Well half of them do. Around the radio they don't light up nor does the radio display light up. The blower doesn't function as of now. Link to comment Share on other sites More sharing options...
