Hi All:
I've done some searches on the forums and it seems some other people have had similar problems as I'm having, but nothing exactly like my symptoms.
I've got a 92 Astro with power windows and I've been trying to get my passenger side to work properly. Having some strange problems. Here's what I've done so far:
1) I've repaired all the wiring in the passenger door boot. Spliced in new wiring to repair broken wires.
2) I've tested all the power window wires on the passenger side with a multi-meter and I'm getting the appropriate power and the grounding is OK
3) I've replaced the power window motor with a brand new unit.
4) I've replaced the passenger side window switch with a new switch.
My symptoms:
1) After fixing all of the above, I noticed that the window motor would engage for "UP" but not "Down"
2) I could make the window go down by bypassing the switch with some leads (indicating the window motor works properly and the problem was with the switch)
3) I replaced the passenger window switch a 2nd time with another new switch and the window worked for 1 day.
4) After initially working for a very short time, the switch seems to have failed again and the window will no longer go down, only up.
Could I be burning the passenger window switch out somehow? I can't think of any reason that 2 brand new switches would fail the exact same way. Has anyone had the same problem or knows what might be happening? I don't see any shorts or overloads with the multi-meter so I'm really confused.
Thanks in advance!
Andrew
