Heated seats, mirror defroster, HVAC, and Airbag indicator

[freefallerz]

I have an intermittent problem with the following items;Heated seats, mirror defroster, HVAC selector, and Airbag indicator light coming on. Sometimes they all work at the same time, and sometimes they all don't work at the same time. I am wondering if there is a relay that controls these items or if I have a problem with the TIPM. If anyone can steer me in the right direction, it would certainly be appreciated!

First things first. Check all of your grounds and power lines at and from the batteries, to destinations and all grounds. Make sure they are all crud free, tight, use dielectric grease on the grounds. Most intermittent electrical problems are caused a loose, or corroded ground.

Check fuse box: MAKE sure all fuses and relays are seated properly, also includes in auxiliary power box if you have.
