Tow Truck PDL's ?????

[Mike M.]

I expect the big stuff, I'm prepared to handle it, but, the little things drive me nuts.
I would prefer to fix this myself, rather, than take it to a dealer and for $300. be told the party line that it worked fine, it must be my imagination.
My puller is a '98 Silverado.
P/S functions perfectly.
The D/S Power Door Lock is the problem.
Manually - works fine
Key fob lock - works fine
Key fob unlock - nothing, nada, zip.
I was able to remove the small trim piece near the inside handle, nothing obvious.
If it is the switch, how do I access it without destroying the door panel and all of the clips?
Any tests before I get too crazy?
Thank you and HaND

Thank you, Dave. Looks like I will be practicing my head stands.
One thing, pressing the rocker switch on the armrest, results in the same in-op situation as with the fob.

OK. I double-checked myself.

The Module provides the B+ for drivers unlock for both fob and manual switch. So, it still makes sense: It's the Module.

Dave,

If my fob won't lock or unlock any doors ('03 GMC Sierra), resynching doesn't help and the fob tests "good" at the dealer, is it the module? Or do I need to "reprogram" the computer as the dealer states?

Door switches work fine.

I'd be happy to get my fob working again.
