Tail gate, cruise control and park auto unlock all quit working at the same time. Any sugestions? Comments? Im baffled.

Welcome to the forum Lee.
Have you had a chance to check the fuses, to see if any are blown?
I find when looking at these fuses it is hard to tell if they are blown.
I use a VOM to confirm if the fuses are in good working order.

Dude, that multimeter is OLD. I use to have the same one!!

Ya I have a few more modern ones Mike, But I still like the ole anolog style!
You must have also purcahsed it at Radio Shack , I think it was a $15 special!

Seen loose connections at the body control module(passenger side under the radio behind the kick panel) cause weird issues. Wiggle the harness at the connectors is a good way of inducing the problem to find it. My question is has any recalls been done recently? I now of at least one for a brake lamp malfunction and that involves the body control module connectors.
