I have a 1996 316i 4-door saloon in which the nearside windows failed to work at the same time, I have tested the motors by disconnecting their leads behind the door panels and they are both OK. I have requested help from the forum before but still cannot completely identify whether this model used a Comfort relay or a ZKE control module. I have removed the glove compartment panels and have located the following electronic units.
- The ABS control module
- Two other modules, one with a blue multi-wire connector and one with a yellow multi-wire connector
- A blue relay module
I have disconnected in turn both the blue and yellow connectors, but the problem symptoms do not change, ie the near-side windows still do not work but the off-side window still do so I assume these modules have nothing to do with the electric window operation. Removing the relay does stop the off-side windows from working.
Where is the control unit for the windows possibly located or any other suggestions.
