My backup lights don't work. All other lights do. Any thoughts? Is there a switch in the shifter that could be bad?

 

Either fuse 4, backup switch if manual, or shifter assy if automatic :

 

I checked the bulbs, they are fine.

 

Thanks ALA-XFIRE, now the directionals quit, are the connected in any way or a different issue?

 

1. Fuse #4 in the illumination control module ( headlight switch )
2. multifunction switch ( the turn signal stalk )
3. The light switch itself

Do the directionals flash with the hazard button ?

 

The directionals flash with the Hazard button?

 

Now sometimes they work and sometimes they don't. Does it sound like the multifunction switch?

 

Sounds like sumpins loose somewhere, and the stalk is a good candidate.

 

Thank you sir!!!

 

Have you had the ICM out or played with it somehow? I caused a problem on my old NA by not connecting a plug securely and some lights did not come on.
Pushing the plug on tight solved the problem. You could try another ICM if you can lay your hands on one, they are cheaper than a multifunction switch.

 

I'll try removing it and checking the connections.

 

No need to remove it, just drop the panel under the dash and it comes down with it.
The instructions to remove the panel are in the Sticky Key Fix PDF. Print it out and follow the instructions.

 

Again, I thank you. You guys are always there to help.

 

Well, the directionals were a loose plug to the headlight switch (ECM). Now if I can figure out how to trouble shoot the backup lights? I do have a bulb out warning light when I turn on the headlights.
