I have been wiring up my power windows. Here is the problem, when hooked up to a battery the driver's switch does not operate any window. I can however jump the correct wires coming off of the harness at the switch and operate the driver's window. I did some basic continuity testing on the switch and it checks out. The terminals in the on the switch connector seem perfect. My only thought is that since I am using a battery which was dead before I started charging it (an hour previous), maybe the switch has too much resistance to it so too low of voltage reaches the window motor... Seems rather far-fetched though.
