Hello. I had problems with my heated seat and had to change the Master Door Window switch on the driver side. when i took the old switch out the the door chime was working. after a few moments it stopped working. the next day i got the new switch and installed it and the only thing it would turn on was the driver window. Locks didnt work from that door, passenger windows dont work from that door. i unhooked the battery for a few moments to see if it would fix it. Now im getting warning on my screen as in, service 4 wheel drive, service tire monitoring system, hood open (even though its closed) My seat wont move on the driver side.Blinkers dont work, Break lights stay on. i can turn the key on and the lights will come on but the switch to turn them off and to parking dont work they just stay on. Fog lights dont work. FOB key wont work. I have no clue what happened. anyone have any guidance on this?

On a LTZ that is not just a switch it is called the drivers door module and controls the door locks/windows/ heated cooled seats/door chimes/power fold mirrors etc. You can't just swap these modules.

You have to take the truck to the dealer and they have to program the module to your truck and clear codes from all of the other modules in your truck. Once the module is programmed all of the functions that are not currently working or acting weird will once again work upon completion.

The larger question at bay why did you replace the module what was acting up that pointed you to replace it. It definitely sounds like there could be other problems and a good part was replaced thinking it would fix the problems only to have caused more.
