1. The motor will raise and lower the window when connected to 12 volts (eliminates bad motor?)

2. The passenger switch works on the driver’s window (eliminates bad switch?)

This leads me to believe the power window relay is bad. But, I read here that the relay was good if one door window works (the driver window works and goes up and down correctly)

Pretty sure I wrote down all the wires correctly by color and location.

Need help with:
1. Need to know if relay is the problem if door switch works
2. Need to know if there is a way to trouble shoot the relay
3. Need a wiring diagram for each the three door switches.
- Driver and Driver – Passenger switches have red motor wires and the passenger side has the blue ones.
- All three switches have a brown (ground) and a red/white and a red/black wire.
- Need to be sure I have them all in the right positions as marked on the bottom of the switch numbers 1 thorough 5

THANKS

Hope this helps. (For our '86).











Good luck,

pm me as needed.
