power windows..again
I have another power windows question; I removed the 
passenger side power window switch to test it for resistance. When I looked at it it wasn't what I thought it would look like. It has 5 terminals, so now I don't know which terminal is for what. Could anybody enlighten me on how to test it and what each terminal is for?

Been a long time since I messed with one of those....If I remember correctly those things are double pole double throw momentary switches...kinda tricky to ohm out. 
I wouldn't worry about the switch just yet may be track down the wires/leads to the window motor and see if you can run that with some jumper wires to see if the motor or wires has an issue.

I'm not sure the light bulb replacement was the fix; he may have just moved some wires around in his door enough to make contact. Anyway, I think all my lights are working.
Looks like I'm going to have to take the door apart. I remember what a hassle the other door was!!

For my '88 the switch wiring is:
-Pink==power from fuse block to Pin A
-Black==ground to Pins B & E
-Lt Blu==UP power to motor from Pin D (with ground to Pin C)
-Tan==DOWN power to motor from Pin C (with ground to Pin D)
Switch active position contunity is:
UP==A-D continuity; C-E continuity
DOWN==A-C continuity; D-E continuity
If you jumper Tan to ground and Lt Blu to +12Vdc the window should go up.

It seriously worked on my '94. I think the courtesy light bulb in the door panel completes the circuit for the window motor or the switch. I also removed the master switch, disassembled it and cleaned a lot of gunk off the terminals.

Another stupid thing running right headlight door "close" wire thru relay and left one directly (w/o relay) on 84 Vette.
Here is another one for you: on some cars alternator circuit is going thru battery bulb in instrument cluster, so if bulb is dead alternator doesn't work!

Yes but the schematic would show that. Some folks couldn't read one if they had it!
I believe that because GM engineers decided to run headlight circuit thru instrument cluster in 98 Saturn. That is really stupid!

I replaced the bulb and the window worked. I thought to myself "WTF?".
Oh well, one less thing to fix.

So does that mean you have no degree and can't read. Somehow I think so. Sucks to be you.
