Replaced master switch and windows will still not work

It is getting power as the light is lighting up but still nothing as far as controls. Window lock is not on. I’ve searched and can’t find what my next step should be. 91 3.0

I've seen a lot of issues with the wiring harness in the door jamb of the driver's door.

Since you don`t mention did the windows ever work ?

You did check both switches and know the one in the truck had failed the new one tested good.

Have you jumped the motors to see if they work ??

Truck running or battery charger hooked up??

I have had some due to old age would only work if the engine was running and the system voltage was above 12.5vdc

Time to break out the meter and get some real voltage numbers

Do the door locks work??

It might be a problem with the door control relay

both door switches in the open position ??

All windows worked up until 2 days ago. I threw my son the keys to roll up the windows as it was about to storm and all rolled up but driver. Did a quick inspection of switch and it was burnt. I was able to take the switch apart and get power to the window to get it up before the storm. I tried to salvage the original master switch but it was beyond my capabilities so I purchased a new master switch installed it and still nothing works. I’m gonna take the door apart this weekend and look for broken or knicked wires and pull the harness and check it. Door locks don’t work nor do the mirrors.....I hate electrical problems ����˟♂️

I'm not sure what light you are referring to, but if it is tied to the dash lights or courtesy lights it is on a different fuse than the power windows, check your fuses. the burnt wires/switch would lead me to believe you have broken wires in the door jamb boot like I mentioned in the thread that I mentioned in my earlier post. read my posts carefully!

I read it and appreciate the link...will be checking the boot and all the wires tomorrow when I can get time to get the door apart. Again thanks for the help and I will update tomorrow. The light is on the new master switch it’s just a dim backlight on the driver window switch itself.

All wires in jamb looked great not a kink in them. I reconnected them outside the jamb for now until I get this gremlin fixed. Is it something as simple as a fuse I’m overlooking? Electrical is not my thing so any help would be much appreciated. Kinda hard to ride around Va with no windows or ac this time of year

Did you get the correct switch ??

Even though it plugs in the pins might be different

Pins on the switch might not be making good contact with the Truck Harness

I pulled it off of another working runner...could the door lock relay have anything to do with it?

Yes indeed the Window Voltage goes through the Door Lock relay .

Was the new switch the same year ?? Still plugged in ??

I have had unseen Corrosion just about drive me crazy the meter things checked good plug it together it did not work .

plugged in and working fine when I took it out. Could I have fried the door power relay trying to get the window up?

You said you got the window up by hot wiring it? This leans towards a difference in the old and new switch, maybe a simple bend pin or loose connection..

The windows use a self resetting circuit breaker, not a standard fuse (little silver rectangle?, iirc)

I would inspect the wires inside the door for shorts/abbrasions. Maybe sniff at the control module (relay box). Check the switch continuity is as expected.. Then proceed with loaded voltage drop testing..

That little hole in the breaker, put a paper clip or something inside it to reset it. I have an extra one if you need it
