I am the second owner got this truck from my grandpa when I was 16. It's completely original and having problems with the power windows.

The passenger side window works great from the passenger side but the drivers switch won't let the passenger side window go down only up. when you try and let the window down the engine and lights bog down almost kills the engine.

The following parts have been replaced: Both window switches, both switch connectors and the passenger side window motor.

I can use as much help as possible, let me know if anyone has an answer to what could be causing the issue, i'm thinking it's a wiring problem.

Thanks for reading.

Sounds like a direct short if it's either robbing voltage from other systems or putting to much load on the alt. These power window systems were done so stupidly IMO.
