Power Window Switch Replacement
I went over a speed bump in the road
and the driver's window went down by itself.
Worked the switches and determined
they needed to be replaced.
The inside mechanics seemed sloppy &
loose, the electrical contact seemed
hit and miss, intermittent.
Ordered new Bosch switches for
19.63 each, $46.87 Total w/ UPS shipping
from Autohaus Arizona
Part # 0343302003
Tools that are needed.
Flashlight, Medium slotted screwdriver
Needlenose pliers, 1/2 - 5-8 " Wide flat file.
Dissconnect the battery.
Loosen the Control Panel by removing the three
chrome thumbscrews and pull it slightly forward.
( This step may not be needed in every case )
Pull the old switches out from the control panel,
this is simply a compression fit, there are no
screws, bolts, or retaining clips. Be careful but firm.
Using a pair of needlenose pliers and a slotted
screwdriver, careful pry the female portion of the
connector off of each terminal, do your best
to keep them together in each group of four.
Don't sweat the colors, it's very clear.
Take a flat metal file and gently work the
bottom of each square switch hole, you will need to
remove just enough metal to squeeze in the new
switch, depending upon your file, this won't take long.
Probably between 1/32 and 1/16 of an inch of metal
needs to be removed, go slowly and test fit often.
Using the wiring diagram below, reconnect the terminals
to each switch, once completed, reconnect the battery
and test each switch before pushing them into place.
Assuming everything worked as it should,
dissconnect the battery again and push the switches
into the holes and place the panel back and
retighten the three chrome thumb screws.
Reconnect the battery. You're finished!
This whole process should take you no
more than 20-30 minutes.
