Bad passenger window regulator?

Recommended Posts

When moving the passenger window up and down, it makes a screeching noise.  I took the door apart and did not see any interference, binding, or anything that looked out of the ordinary. I lubed the regulator pullies (at least the ones I could get to on the bottom), but the one that is on the top LHS of the passenger door is covered by the door metal structure - which seems to be where the noise is coming from.


I attached a short video of the window operation and the noise is clearly heard.  Can someone confirm if this is a regulator problem?


Just in case, any recommendations on a source of good aftermarket regulators for a reasonable price?

Frayed wire making noise while going around the pullies. I got a salvage replacement part in good nick for less than $40..

Non-OEM replacement parts are pretty cheap too. Around $60 online..

wow. amazing. paid close to $400 for mine from Porsche iirc

Agreed, definitely the regulator.  I just did this job last weekend.  Not too bad, really.  A couple of finicky things, but you did the most time consuming part in getting the panel and foam off.  One tip that really helped me was to put blue painter's tape to mark where the window should line up in the regulator - put it both on the top edge and one of the side edges of each bracket.  This completely eliminated all the fiddling with aligning the window after you get the new regulator in.  I used the Uro replacement, cost ~$150 on rmeuropean, works and sounds great.


One other note...don't forget to plug the sensor plug back into the connector where the latch pull connects (small, black two-wire plug).  I did this the first time and it makes the car think the door is open...duh.  There is not much lead on that plug, though, and it disconnected by itself when I pulled the panel off, so I wasn't aware of it when I put the door back together.  There also isn't much lead on it, so it's a litte bit of a pain to plug back in as my hand barely fit behind the panel to access the plug due to the short lead. 


If your clips are old or broken/brittle, order those too since they're cheap.  99950750540.  I also used a door panel removal tool, but you already did that!
