w210 rear windows regulator
 

Hello, I just picked up the rear window regulator for my car. I had a quick question. Is there a certain procedure for the install ie, should the window be down or up, should the windows be in any position. Does the motor know when the window up or down ?

You'll want the window down before disconnecting the rear window switch (in the door panel) so you can remove the clip that keeps the window sliding jaw attached to the regulator.
I usually 1. lower window 2. remove door panel and rain shield (plastic sheet). 3. drill rivets out (you got 4 rivets right? You need a BIG rivet gun to reinstall the regulator) 4. You can then move the black clip on the bottom of the metal channel of the regulator and move the regulator back or forth to remove the window sliding jaw from the regulator. 5, Push the freed window up to the top position, usually the window run channel will hold the window "up", or use a piece of duct tape temporarily if you don't trust it to stay up. 6. Remove the wiring connector from the motor and remove the regulator and motor as an assembly. 7. Remove the 3 screws holding the motor to the regulator, then the motor is "twisted" and the motor is pulled off and transferred to the new regulator.

Putting it back together is pretty easy. Just put the regulator/motor assembly into the door, you will notice the metal tabs that engage into the door to allow it to be held in place prior to rerivetting. Be sure to pull the window back down and engage the window channel back onto the sliding jaw and reclip it. Usually the new regulator sliding jaw will already be at the bottom of travel, so it should go back together as you remember it.
The motor does "know" where the window is after being synchronized. This is done by raising the window using a "soft touch" on the window switch (either front or rear switch), NOT the one-press feature. Raise it up using a soft touch on the switch (first detent in other words), and once the window is completely closed, keep holding the switch position for another few seconds. You will hear a very soft tap from the window motor, at that point it is synchronized. You will need to do this after replacing the motor (when you are done) and also anytime battery power is lost (disconnected or dead battery) you need to do this to all the windows.

Thanks, I will try it in the morning. I only got 3 rivets from the dealer, I believe that was all I needed. I couldn't find a big enough rivet gun for the 3/16 steel rivets.. All the guns at Home Depot were not for steel 3/16 rivets.. only aluminum rivets..... Anway I will havd to shop in the morning for the propergun..

Wow, changing the windows regulator was so easy 30min. Anybody who can change there own oil and brakes. can easily change the regulator. I had so hunt down a pop rivet gun that was big enough, my father happened to have one, It was a little hard but it worked.
I should probably open the other door up and grease up the track and cable before it breaks. Mine broke where the cable goes into the white plastic piece. I added a little more white lithium to the cable and track. The one that was broke seemed to be a little dry like it needed to be lubed up, or it wouldn't have broke

I used these post to replace my Left rear window on my w210. It went very well. I had a small pop rivet tool but found a pneumatic blind riveter imported at NORTHERN Tools for about 60$. It worked great and will be a great tool to have in the shop. Harbour Freight has them as well.
