The first Tech tip is that $1700 item the dealer can fix that might only cost you a little bit of time, or a little bit more.

This is usually something simple that you can fix, or a competent mechanic can fix with your information.
The simple solution is a bad ground out of the module, or the module itself has a broken solder joint. Here is is on the 2003 trail blazer.
I’ll have more on this same issue with the C5 soon
