99 Z3 M Roadster Window Issues!!
Hey All,
Im working on my friends fathers 99 Z3 M Roadster with 9000 original miles! Ive done a list of things to it and everything has gone to plan besides a few broken trim pieces and one major issue. The Drivers side window will not initialize and will only go up an inch or two every time you press the button. Both up and down. I swear I have tried every initialization procedure I could find online. Decided to pull the door panel to see if there was anything obvious, found what looks an aftermarket window motor with the pos and neg wires spliced backwards. Ordered an oem motor and replaced today and no luck. No initialization, same exact issue. I do have ISTA and ISTA P but have had no fault codes. I have greased everything in the door, even pushing up on the window while putting the window up doesnt change anything. Really cant figure out why this window will not soft touch up or down. TIA!!
