Dead short window switch

[Clcarp57]

'85 C10, bought   truck window regulators to speed up function of windows.  Drivers side works fine. Passenger side works fine.  Passenger switch on drivers side works fine in up mode, dead short on the down button that causes interior light to dim and stereo to restart (modern day single din). Wiring diagrams are confusing.  New switch, but old switch does the same thing.  I'd like to be able to run a jumper from drivers side passenger switch to the passenger side.  Any ideas? I'm lost.

I am confused on what you are actually trying to do...  Are you trying to find the short or?

It sounds like you installed aftermarket power window motors and switches. We can't help you unless you post the wiring diagrams and detail what you did.
