I've been reading alot about the WIN module in my truck and have come to the conclusion that there are far too many sketchy electronic components for my liking in this vehicle.
I've posted about this a while ago and things have gotten worse in some areas and better in others.
About a year ago give or take a month I purchased new tires and within a week started having TPMS problems. (left rear) This eventually cleared up once I lowered the over-inflation level that the tire technician placed them at.
around the same time I started having Intermittent function of the Integrated Key Fob Transmitter. Sometimes I could unlock the truck on the first click, other times I had to press the unlock button several times. And yes I changed the batteries in both FOBs and there was no change in the reliability of function. When inserting and turning the FOB the truck starts just fine, shuts off just fine, and recognizes both keys.
Recently the remote function has ceased altogether. I hooked my scanner up to the truck and looked at the WIN module. I verified function of the module and the recognition of both keys.
Whats not being seen is the FOB button presses. Nothin' I've got a few more things to investigate before giving up and getting a new WIN.
It should be said that I have an aftermarket remote start module installed and I'm going to remove it to see if that had or has anything to do with this issue. I only hope that if it is causing this problem that it didn't burn the RF function out.

Any opinions? questions, Comments?

Also, if you have AlfaOBD (or a scan tool), you could do a reset on the RF Module. When I had all kind of gremlins with my TPMS and some with my FOBs (rotary ignition knob) being iffy at times., The RF reset cured the headaches after I installed a new TPM in the full size spare tire.
