Is there a penny stuck in the lighter port?
I got this problem solved. It was a blown fuse in the power distribution box ubder the hood. Could find no shorts or reason for blown fuse, Replaced fuse and working fine now.
Buick didn't see this one coming but they don't have a long burn life. I had to replace both on my 1992. For some unknown reason, they burn after a period of time and need to be replaced.
If the bulbs have been replaced as well as the fuses then there could only be one reason for the issue. This is the relay between the switch and the fuse box is blown.
Yes, but it is not a DIY repair. Working with the SRS can be very dangerous. For this reason seek professional help.
Just replaced the headlight bulbs in a 98 Grand Cherokee that had the same problem. It had the wrong bulbs in it. It had 9007's in it. Calls for 9004's.
The most likely reason why the interior lights of a vehicle are not working is because a fuse has blown. That is especially true if all of them are not working. Get out your owners manual. See where the fuse box is located. Find the particular fuse, and replace it.
Yes if the wire is part of the brake lamp switch

The door switch is bad. I have replaced the drivers side door switch on mine for the same reason.
Nonfunctional LightsI'm not familiar with your 2002 Gran Prix, but the problem you describe is universal to all vehicles.The fact that the "third" brake light [in the rear window package tray] IS WORKING, indicates that the brake light switch IS WORKING properly!!!!!That suggests that the reason that the other two brake lights are not working is that there is an "open" condition in the wiring circuit to the other two brake lights. This is confirmed by the fact you replaced the lamps [bulbs] in those other lamp holders with known good lamps.There could be several causes for an open circuit, but the most common include:One of the connector plugs in the wiring harness to the brake lights has become disconnected, orCorrosion has built up inside of one of the connectors [one that feeds both brake lights, which will be in the circuit "ahead" [upstream] of where the wiring harness "splits" off between the two brake lights].Very remote is the possibility that the ground wires on both light assemblies has been disconnected, cut, or corroded.
The most common reason is a bulb failure. If the bulb is known working, or replacing the bulb does not cure the problem, look to the fuse, switch and wiring.
The backup lights are a different bulb, then the turn signals and brake lights and The Number 1 reason would be that the bulbs are burned out and need replaced. Good Luck and Remember.Change Your Mind, Not Your Oil.Use the First In Synthetic Motor Oil's.See My Bio For Information & Contact Details.
