Probably the motors went out .check at the windows motors in any power going to the motors when hitting the windows switch. If power going to motors good then replace motors.

I would think its fairly unlikely that both motors failed at the same time, my money would be you're not getting power to the master switch. I'd check for power there first, its easily accessed (as you already know). If you have power there, I would then proceed like gonzo said and check the motors for power.

The service manual for the truck is available through a simple google search. You'll find all the wiring diagrams and connector pin outs you'll need inside of it.

 

Correct Mr mac! One step a time is key before you start losing it over something small....LoL

take apart your switches, and clean the contacts. Most common cause is fuzz/dust on the contacts. If you do have motor failure: take it from experience, don't order just the motors, order the whole assembly. Plug and play vs. hours of trying to wind and resurrect cables. But most likely, the issue is in the switch.

 

Got home went and checked no power to the front switches so your on the money Mac

Remove the drivers side kick panel and check the bundle of wires that run down from the dash near the Emergency brake. The windows, but mainly the door locks, in my 05 started acting up and randomly not working. I traced the wires from the door and found that the Emergency brake was rubbing against the bundle of wires and actually caused several shorts. Started a thread about it way back in the day that has pics. Good luck, electrical shorts can be a pain.

Yeah I'll check it out. I looked up the service manual so when I get the time I'm going to jump on it. Mac it's funny I had an instructor tell me that when I was going to UTI
