Power windows issue

this is the one with the 4.7L.

Naser,

I attached the entire power window schematic. The fuses/relay are in the first pic. I overlapped them so you can follow them easier.

If the fuse and relay are good, check for power to the pink wire (which changes from brown) at the driver's master window switch.

Let me know if this helps.

Already checked pink wire, no power. Fuse 30a under left side of dash is okay.

Either the relay is bad or there is an open in the wire. The fuse supplies power to the relay. Check to see if there is power at the brown wire off the relay.

Let me know.

I can't find the relay.

It should be in the fuse/relay panel on the left side under dash. That is what it indicates in the schematic. If there is a rear power window, it shows that one either under the hood or behind the seat based on if it is an extended cab.

Naser, it doesn't indicated it in the schematic, but I'm questioning if it is one that is a built in (PCB).

This is extended cab, none if the 4 windows work whether from main switch or each window's switch, not even a click sound. I checked every fuse under left side and all good. Can't find any relays.not sure really.

I attached a pic below. I suspect I know why you can't find the relay. I believe it is part of the PCB in the body control module. See pic 1

Naser, I attached two more pics. I highlighted everything from left to right. Pic 2 is the upper portions of the two pages and pic 3 is the lower. I did it this way because I could highlight things differently allowing you to see the system in a more understandable way.

Let me know.
