When trying to roll the passenger side window down from the driver side it won't go down, but it will go up, and it goes up and down when using the passenger side switch.
After studying the wiring diagram in the Haynes manual I did some voltage checks. I checked the voltage in the wires that plug into the passenger side window switch. The wires seem to be getting the proper voltage (DOWN circuit got 11.7 V when rolling the window down, UP circuit got 11.7 V when rolling window up.)
When checking the same wires while using the switch on the driver side, I got the correct voltage when rolling UP but got zero voltage when rolling DOWN. It seems like the down circuit is broken but I can't tell where. Any help would be appreciated.
By the way, this problem happened when I replaced the passenger window motor/regulator (cable was broke). There are two 6-pin connectors in the door and I accidently switched them when plugging them back in. I should have paid more attention to which one went where. Anyway, when I connected the battery up I smelled an electrical burning odor for a minute or so. Nothing worked, so I did some troubleshooting and figured out the connectors were plugged in wrong, switched them back and everything worked fine except the problem I describe above.
