Check your battery cables and ground cables for good connections first.

The standard answer when the ghosts start giving you fits. When Steven says check them he means not just tight. Needs to be clean and corrosion free and also check for corrosion inside the battery cables insulation. Lots of ground wires to locate and inspect. Good luck and welcome to the forum.

Welcome to the forum.

Listen to what Steven and Ron have suggested. These vehicles get really wonky with bad grounds and low voltage.

While you are doing the checks that have been suggested, with both battery cables off disconnected from the battery, cycle your head light switch a couple times and pump the brake pedal a couple times to bleed off any stray voltage in your system.

This may or may not help. I don't know where mine are on my 2002 Tahoe till I look for them. I did go into All Data on my rig and pull up some possible TSB's that could help. You will have to sort them out.
