Angry Passenger window does not work from driver or passenger door

Hello fellow s2k members. I have been reading a lot of posts in regards to electrical issues with the passenger window. Mostly the discussions have been around the window lock (which I checked), bad fuses (checked and are good), and lastly the softtop switch fails along with the passenger window. My situation is different from the above due to my convertible top is operational, however, when I flip it down the passenger window does not roll down with it while the driver side does. I have checked the passenger side window switch with a multimeter and the wire to the right of the black is not reading 12 Volts like the other 3 wires. I ran the power master switch test and it basically tells me I have either a faulty passenger window switch, faulty power window motor, faulty convertible top control unit, bad ground, or open wire. How can I identify the true problem without buying all the above components that are very pricey! When I press down on the driver side switch or passenger side switch it makes a clicking sound from the convertible control unit but nothing happens. When I press up it makes no noise at all.. Can someone please help!?!?!

Blue wire to the right of black shows 0 V


Passed all these tests


Failed 13, 12, and 6

i don't know if this helps, but when i bought my car, the passenger window could roll down but not up. i didn't check it when i bought it but asked the previous owner. he told me to hold the passenger switch and master switch together to roll up.it worked together but not separately. so i bought a passenger switch on ebay. a no go. my son's friend told me to try buy a master or drivers side switch. nothing to lose and not too expensive on ebay. it worked. lol. true story!

Thanks for your story and I will try pushing both switches up at the same time to see if that does anything. I'm trying not to replace switches, motors, top control unit before identifying voltage through a multimeter. I'm hoping someone on here can provide electrical schematic/tests to perform on the passenger side/convertible top control unit of the vehicle.

I think I have a PDF of that circuit on my home computer I'll check it when I get home.

Best way is to eliminate the possibilities, start with window motor, does it operate with direct power. Something like this:

If the motor works then to switches, I forget how they're wired, but by shorting the contact that switches on both sides and the window doesn't move, you probably got a controller issue, if it does move you got a problem with a switch. If I can find that schematic I can give better toubleshooting ideas, I'll get back to you.

Thank you for the electrical schematic! You're my hero away on business travel but this is very helpful!!

Update: Applied direct power to the passenger side window motor and it did not operate. I have ordered a new regulator/motor and should arrive end of next week! Thanks for all the help

Hey, just took a look at the schematic and more importantly the connector terminal view which I hadn't posted - the
passenger's window motor has two cavities/wires -
harness RED/BLU to motor BLU/WHT: Window up +12v
harness RED to motor BLU/RED: Window down +12v
Motor is apparently grounded to the door rather than through a wire, which is not obvious from the schematic alone.
Just wanted to make sure you tested the motor this way.

That's how I tested from the schematic you sent. I conformed there is power coming from the switch into the motor but the motor does nothing which suggests the motor is bad. I am hoping everything I tested was correct!

sounds like it, I was just making sure because the terminal view makes it much more clear what each wire's purpose is.
