PFL E30 Electric Windows

Recommended Posts

Hi All,

Wondering if someone can help. My 87 M325i has developed a bug where the electric windows work intermittently.

I have started to hear an arcing sound coming from a relay behind the glove box whilst driving. This doesn't last very long but when the arching is heard, the windows will work. All other times they don't.

I have pulled the relay out and put it back in. This prompts the windows to work again for during the duration of the trip. Once the car is turned off it reverts to not working again.

I am not sure if this is coincidental but the windows sometimes work when the doors are open.

Thanks in Advance.

First up - change the relay. You shouldn't hear that sound from it.

After that, it'll be a case of checking wiring to the doors. Has it chafed through on the door/body connection? You need to look for shorts to earth.
