My digital dash stop working after an after market radio was being installed so i had the factory one put back in but it's still not working. the heat buttons work but i cant tell the temp.

check that dimmer is turned up ---and check connections around where radio work was done for damaged disconnected line connector also check dash fuses not just fuses from radio --or your radio may not be compatible to your dimmer circuit -most oem radios display are Incorporated with dash functions and after market ones are not

You have a short (crossing wires) to the radio....is the radio factory or after market?

BAD CONNECTION? DID YOU PLUG IT BACK IN? OR DAMAGE WIRE? OR PULL OUT FROMM BEHIND DASH

either remove the battery terminals each stopping point
until you check starter and ignition and alternator

if the parasitic drain started straight after the radio install
return to that after market installer
and get them to explain why

why not open vchatter

I have come to find out that in the 90's auto makers started installing factory amplifiers in their cars so they could use low wattage stereos in the dash. It's usually a blue wire off the stereo that runs the amp, maybe it couldve become disconnected? I also know that even if you put in an after market stereo, this wire must be hooked up or you'll get no sound from the speakers. hope this helps.

Must have special U-shaped tool to release latch on both sides of radio. Tools are sold in sets as it requires one on both sides of radio. Insert tool about a half inch and the slightly push towards outside of stereo to remove. A little tricky for first timers

If you buy another factory radio it'll need the unlock code to work with your factory alarm system. But if you go with an after market radio it'll work just fine, your alarm will just think there's no radio installed.

all you gotta do is carfully pry the dash panel off (prying from the far left end is easiest) completely remove panel. then there are 2 clips that hold the factory sterio in place. push on the both clips while pulling the radio out. simply disconnect the wiring harness from the back of the radio. using an adapter avaliable at your local radio shop (scosche p/n gm02, mdarb and gm1483b) wiring harness, dash install kit, and antenna adapter. then simply match the colors on the new radio's harness to the adapter harness, crimping each connection with a "but plug". then simply follow the instructions included with the dash install kit to assemble the kit.connect the antenna adapter to radio, plug in all cables. test to see if everything works properly before the final install. install sterio into dash install kit, re installing kit where origional radio was. then simply put the panel back in its place by firmly pushing on it untill it snaps into place. then enjoy your new radio!

Most factory stereos are wired to the dash dimmer switch. Usually if the dash lights go out after an after market stereo installation, it is because the wire that originally went to the factory stereo is not used for after market stereos. Double check the fuses and ensure the wire that controlled the lights on the factory stereo is not grounding out on something.
