I hate this light. It is not working. I replaced the bulb with the correct part. Flip the switch and nothing. The old bulb was clearly bad as it had the burnt out look. So why wouldn't it work? Everything else in the car that's electronic is working as it should. I would have a hard time believing that GM had a relay or fuse for this one part. Correct me if I am wrong. Any suggestions would be appreciated. BTW there doesn't look like there is any corrosion or damaged to any of the wires. They all look almost new. Aside from a little dust that always accumulates in old cars. Thanks.

 

Get a meter, put it on the voltage setting, put the two probes on the prongs that are used to hold the bulb in, see if you have voltage. Then go from there. Its not uncommon to get a bad bulb in a brand new package.

Let us know.

 

Good suggestion I didn't even think of that.
