I'm thinking a bad ground somewhere? Does any one know where these are grounded so that I can check it?
Thanks in advance!
Did you clean the contacts within the master switch assembly?
My driver's side switch for my driver's side window was sporadic.
Take it apart and spray the hell out of the contacts with electric parts cleaner and wipe clean with a swab.
It made all the world of difference for me.
I'm a little hesitant to say that is ultimately your problem because it doesn't work on your passenger side either. Not sure if the contacts are the issue because they are physically manipulated to connect the circuit.
As for your question, I had my 98 door panels off and the wires that run up into my passenger side, and driver's side switch (and assembly) were all just bundled together and ran into a quick connect that plugged in under the switch. I am not sure what color wire is what but they all ran through the rubber pass through and behind the kick panel. Then they plugged in to a massive connector of many wires.
Here's my master assembly before and after:
The passenger side switch, for the passenger side window, are those copper and silver circular contacts in the upper right of the bottom pic. The driver's side switch for the driver's side window are those thin copper and silver blades that run vertically in the lower right of the bottom picture.
Hope that helps
