Extended cab, drivers window switch only works the rear windows, passenger switch still works passenger window. I tried replacing the switch itself but still the same problem. Any ideas?

 

That's a known issue with the connectors going bad. I replaced mine from a dealer on eBay who sold over 5k of them, so I'm surprised your replacement didn't work. Where'd you get that switch from? I read a how-to clean the switch, trying searching here or google.

 

Tried cleaning the connections with no luck.... Is there a separate fuse or relay for the front windows?

 

Plan D seems to be splice the front windows with the rear windows so they'd have to go down together.

 

Anyone have experience with Viper car alarms? Previous installed a 791VX and they spliced all the window wires

 

Turns out the alarm also had a window control module that was spliced into the factory wires. I just bypassed the module and its good to go.

 

Glad to hear you found the problem. My rear passenger wouldn't work from the front main because the switch In the rear had gone bad
