Polymer 0 Report post Posted February 10, 2011 Hey all, I have a 95 318i that the drivers window isn't working, I initially thought it was the motor in the door, so I pulled off the door car and powered it up at the plug and the window went up and down fine, I then swapped the switches from the passenger one thats working fine to the drivers one and still doesn't working. I tracked down the clicking noise it makes when you press the switch to a black box behind the glovebox and found the wires from the motor in the door, with my multimeter I checked the output from these wires when you press the switch and my meter shows about 4 volts for about half a second and it clicks off again. I also checked the passenger one and thats getting a solid 12v when you press the switch (as you would expect) Is this likely to be a internal fault in the box? i can't think of anything else to check. unless someone has a wiring diagram or something? Thanks Quote Share this post Link to post Share on other sites
