Thanks for all the input. After carefully reviewing the wiring diagram with a magnifying glass I seems that there should be 12v at each terminal and that pressing the switch grounds one or the other. It therefore looks like the problem is with the motor. I hope it is just gummed up with the old grease that everyone talks about rather than burnt out. I guess I will take it apart this weekend and hope for the best.
Thanks again

Stacy -- you might want to try disassembling the 2 passenger window switches and cleaning the internal contacts -- a skill I found invaluable as a 308 owner (after removing the switch from the door, carefully pry off the outer trim ring, if possible, then the sidewalls of the main housing can be separated enough to remove the rocker part -- then pickup all the springs/contacts/wiping posts that just went on the floor -- just kidding, sort of), or at least test the switches logic with an ohmeter. My recollection is that there's a lot of "interconnecting" upstream of the passenger side motor between the 2 passenger window switches to provide the special logic of either switch operating the single motor. Just a thought...
PS Don't necesarily be surprised by measuring +12V on each lead -- I've found a lot of systems (especially on my TR) to be architechted with +12V always present and something gets grounded when you turn it "on" (but I did not look in detail at the 308 schematic for this case -- I leave that for you). |

There are also one or more relays involved in the circuit. Clean the connectors between the motor and door and reseat the relay. |

There is an article in this months Cavalino magazine that addresses how to care for and/or repair the andiquated cable type power window lifts. |

79 308. My windows have worked ok, the right side a little slow compared to the left. I got in the car the other day and the right side window would not go down. Not even so much as a groan or shudder could be heard in the door. The driver side still works fine. I checked the fuse and even swapped the right for the left but no difference. The next step was to remove the passenger side door panel to check out the wiring.
I checked all the wiring which seemed to be intact. I found two wires leading to the motor. When the ignition is on but the window switch is NOT depressed, I measure 12V at each of these wires with the positive lead of my multimeter on the wire and the negative lead grounded. When the switch is activated (up or down) the voltage drops to 6 volts between either wire and the ground. Still no action in the motor. I may not understand the circuit arrangment because I didn't expect to measure any voltage at the motor with the window switch not pressed.
Any advice or suggestions about how to figure this out would be appreciated.
Thanks
