I have the truck listed above duramax 2500H. For this truck I have two key remotes, neither of which lock or unlock truck, but when unlocked with the key manually the alarm still chirps. Also my seat controls on the seat and seat memory, and heat seat controls don't work on the door. Everything else on the door works, and the passenger side everything works.

Hello,

There is a DDM 4 fuse we need to check besides the other three that run the system. here is a guide to help you check the fuses with the fuse location as well. Also I have included the power seat and alarm wiring diagrams so you can see how the system works and which fuses to check.
