Drivers Door Locks and Window Inop
Door modules
Is there any way to test the door modules without a computer? (Continuity, voltage, etc.) Do you really have to program a new module after installation? Is there any way to get around programming them?
Re: Door modules
Yes, the door module must be programmed, or the new one will not funtion at all.
About all you can do without a scanner is measure voltage to power the module, and its ground. Everything else is communication voltage on the data line. I suppose you can measure voltage on the data line, but then you run the risk of fryiing another module, since they all talk to each other.
The only voltage you can measure is the voltage out of the module to the window motor, or lock actuator.

Window problem with my 2007 Chevy Trailblazer 6 cyl.
My power windows and door locks stopped working on the drivers side of my vehicle and there is a strong electrical odor present and you can see where heat has melted the area where the controls are. Could this be a burnt out DDM and if so what is the typical cost to repair?

Re: Drivers Door Locks and Window Inop
Yes, does sound like the switch / Driver Door Module (DDM) is bad.
That module is approx. cost of $175.
It wouldneed to be programmed before it will work after replacement.
Expect to pay 1/2 hour labor for programming, or 1.0 hours total for replacement and programming.

Re: Door modules
If you have power to the module and a ground, then the switch / module is bad if ALL co ntrols don't work.
