Hi, I'm new to this whole website and I just bought a 2003 trailblazer LS a few months ago. It has many problems with it because it sat in someone's yard for 4 years and the lady that owned it before took horrible care of it but a vehicle is a vehicle so I'm happy with it. Anywho, the most annoying problems are the back lift gate handle is broken internally and the keyless entry doesn't work. I took off the trim on the inside to look at the lock and it's completely rusted and busted. There's some wires in there with it that I assume are for the lock. I was wondering if that had anything to do with the keyless entry not working. I heard that there's a keyless entry module on the hatch too. However all the other stuff on the hatch works fine like the license plate lights and wiper. Any advice would be great and much appreciated. Sorry for such a long explanation.
