ok update i used the modis today and its showing both front doors to be open with new latches any ideas?

[jordanscc]

wow guess im the only one with this prob

The modis showed both front doors ajar but you have replaced both switches. Well, have you inspected the wiring? Is there any codes in the BCM or GEM?

[jordanscc]

yes checked all wires its tricky i can lock the doors with inside lock and shut the door and the parking lamps flash so that tells me the truck knows the doors are closing. and the only codes showing are parking brake loop open with no light in dash and it works as well have tested and deivers seat belt loop open? could this be the vsm also the remote key fob no longer works

Thats interesting. Can you do any function tests with the BCM to see if it is actually working right? Aside from that, it might be better to have your dealership hook their computer up to it. They might be able to reflash the module with an update or something. I dont think I can help ya any deeper and definitely havent heard of this problem before. Normally replacing the switches solves it.

im the lucky one lol thanks alot man

Yay! You win a cookie! Lmao. Seriously though, I think it could be a problem in the BCM programming or something. I wish I could help more but I have no idea without poking around on the truck myself.
