Can someone shed some light on the electrical side of power windows of 1986 sovereign. My issue is wire supposed to carry ground power is also carrying + ve power. I ve tried to check the relays but couldn't find one , however there is a unknown module which I assume is for power windows. Can some one please help me a little on this black module and the circuitry.
the car was abandoned for a long time and was taken apart to do tinkering works. The guy who disassembled everything passed away . I ve assembled most of it back, but couldn't get the power shutters to work. I can get them to work by supplying a direct ground. But I don't like doing it without the original way.

Thank you all in advance ,

 

What are powershutters? Do not understand term.

Are you referring to the door lock mechanisms?

 

I'm sorry power windows my apologies
