Power windows not working- relay? 95 318ti 5 spd, 181k miles Issue: Power windows suddenly stopped working. They were working perfectly fine, been doing some work on the car, but nothing electrical really. Did a few searches and found it could be the module behind the glove box is bad. I replaced all the fuses (yes all 46 lol) as the car was old and new fuses are cheap so why not. Still no luck. I was able to get them to roll-up by inserting key in driver side door and holding to lock position, so I am thinking must be a relay somewhere? Any thoughts? Again, both windows worked well and smooth up until recently. Thanks! |
bump for more thoughts? |
Check the switch in the center console The switch that is near the shifter that is used to operate the windows can go bad. |
I thought so too. But both going out at the same time? I check and niether side is getting power. Has to be further back in the circuit. Is there a relay somewhere? |
I don't know. Seems like if you were able to get the window to go up with your key that any relay would be working. I would get a new switch and try that. |
I checked the voltage coming into the switches with a voltmeter and there is nothing. It seems the relay from the door lock is on a different relay from the window switches. The sunroof also stopped working at the exactly the same time as the window switches. I’ll Try a new switch, but seems unlikely both switches AND sunroof switch go bad at exactly the same time.

It does seem unlikely that it would be a switch since all 3 switches would need to be faultly at the exact same time. I need to dig around for the wiring diagram. Add I too did a bit of googling. Many point to the comfort relay. https://www.bimmerforums.co.uk/threa...ir-guide.3665/ |
Thank you. I need to work on my googling skills as a search a couple time for “comfort relay location”. Looks like it may be the ZKE modeule as mine is 95 and comfort relay were up until 94. The research continues, but 318ri.org helpful as always! |
Try the body module. That happened to me. Sent from my iPhone using Tapatalk |
What/where is that? Regardless I will try that. Thanks! |
Power windows not working- relay? Google it my friend. I had it done by the repair shop so I’m not personally familiar with it or it’s location. But my symptoms were identical to yours Sent from my iPhone using Tapatalk |
Already researching, thanks for the direction. |
