Removing window motor 88 911 cab

Hello - I've searched the forum but can't seem to find out if removing the passenger side window motor requires removal of the regulator as well....seems like it does but want to make sure.

Thanks

I sure didn't have to when I replaced both power motors. Can't imagine they have changed much over the years since the basic design worked great. You will need a racheting wrench to remove a couple of the bolts because access is limited.

There hasn't been a lot of tech info regarding windows/power motors/regulators that I could find on this forum. That said, I have had a "slow" passenger window problem for a while, on my '82 SC coupe, and took it apart last week. Working inside doors can be described in a number of ways, but fun doesn't come to mind!

After panel and speaker removal, and disconnecting the car battery, I removed the 8 bolts (including two at the base of the post near the speaker opening) that secure the window frame, and pulled the frame out of the door (this will be different on your Cab). Then I moved the regulator enough to separate it from the base of the window, and pulled the window out of the door. It's necessary, to avoid damage, to remove the window slot seals, especially the internal slot seal held with clips.

At this point my memory became over loaded. I couldn't get the regulator out of the door, with the motor attached, so I moved the assembly around until the motor retaining bolts were easy access through an opening. I used a 10mm 3/8th" socket, a short extension, and ratchet; the bolts were tight but do-able. I pulled the motor loose from the reg, and took it out of the door. After the motor was off, the regulator came right out.

I'm planning on replacing the motor, window slot seal, and window track that fits in the frame. The piece on the bottom of the window, and the regulator, are in perfect condition, so a good cleaning and fresh grease will do the job.

BTW: When you work inside a door, extreme care must be taken during every part of a job, to not allow parts or tools to push against, and dent from the inside, the outer door skin. I will be back after taking delivery of my parts, and hopefully will remember to take a few pictures.

There's a couple of articles on this in the tech info center:

Pelican Technical Article: 911 Window Regulator Replacement

Motor comes out first, then the regulator, but everything is disconnected at that point so you might as well remove, clean, inspect, etc.
