There are 2 locations for these fuses one being inside the truck on the left of the front console this one is easy to find with the drivers door open, and the othe is under the hood again on the drivers side. i am not sure which is which but one is for the cigrette lighter and the other is for the accessory outlets. just check the owners manual to be sure. if you still cannot locate the fuse purchase a cheap auto fuse tester and check them all out, it is a longer process but sometimes is works better

Its going to be

1) Fuse.
2) Switch
3) Motor

If your fuses are OK and your switch connection is home and good, you probably need a new motor.

First, please review this article: Where's The Fuse?

I seriously doubt that your problem is being caused by a fuse. Your Passive Restraint System has a problem. This could be caused by a driver's airbag, a passenger airbag, a seat belt pre-tensioner, a contact assembly in the steering column, or any of the crash sensors. To find out what the problem is, you must scan your Passive Restraint (or Airbag) module to retrieve fault codes. The only thing I can tell you for sure without properly diagnosing your vehicle is that your airbag system will not function in the event of a crash. The system is designed to disable itself any time the warning light is illuminated. This is to prevent accidental deployment of the airbags due to a malfunction in the system.
