Loss of power to door?
 

I have a 1990 FC3S S5 t2 and managed to lose window power and lock power, but retain power to the door card light.

The switch relay clicks over in both power window switches drivers/passenger. The door lock motor could be dead. But I hear something click over again.

Could it be the power wire feeding them is bad or just bad switches / locks now?

I think the switches just can't do it anymore.

The contacts have been cleaned but look worn / well
