Radio doesnt work - 1999 Pontiac Grand Prix

Modern automotive electronics are keyed to the VIN through the ECU to prevent theft, you must have the radio ID #, and key it into the radio with the number pads on the radio, only the dealership can retrieve the correct code for your vehicle. Probably not what you wanted to hear.

check for inline fuse on radio wire, if not blown-- go to a retail store buy anther radio have it in stalled 200 dollars MAYBE HAVING SOMEONE CHASE DOWN GHOST WIRING CAN COST YOU, MUCH EASIER TO BUY ONE INSTALL IT AND CALL IT A DAY

is it only the radio that dosent work there may be another fuse on the wire of the radio

Check your fuse block to make sure the fuse is good - if so, then your radio may have burnt. Also look on the back of the radio to see if there's a fuse mounted in the case. If it's an aftermarket radio, it could have the light wired to the dash light switch which would make the front light up without radio function.
Hope this helps!

The wire that supplies a live to your radio, runs from ignition down the steering column. You probably have a chafed wire along that loom, as you tilt the steering, the wire grounds so the accessories fuse/radio fuse blows. Remove the panel under the steering column and/or the shroud around the column and examine the wiring.

more than likely its you ground wire make sure its grounded good because if you dont then it could cause it to cut in and and out
