I have drilled out the 2 rivets that hold the motor to the inner door panel and will eventually bolt on the new motor. The old motor is now loose, but still inside the door attached to the regulator. How do I get the motor off the regulator? I am considering cutting a 4" hole in the inner door panel to cut off what I think are rivets attaching the motor to the regulator.

I do not want to remove the motor and regulator as an assy because I can not see (even with a mirror) the glass pinch holders plus the access holes are tiny and I do not want to break glass or something else. And all that is sold is the motor, not the motor-regulator assy or even a regulator only.

I attached a picture with green tape pointing to the new 2 bolt holes and masking tape showing the proposed area to cut out.

Anybody done this or have any ideas?

Bring it to my house and I will take a peek...

Also, I have a wide variety of cutting tools.

Fixed, thanks to Bill, but not sure exactly why. Diagnosing , plugging & unplugging, etc. and all is well?????? Time will tell.
Case closed.

Bill: I did add aprx 1/32" of JB weld to the top of the two tiny plastic posts that push on the switch contacts in the driver door master switch. Still working fine.

OK. How long are you going to leave the door panel off???

It seems weird now to see the picture you posted at the beginning. It is so familiar, like looking into a mirror.

I put the drivers switch into the drivers door panel today. If all keeps working I will put the passenger door panel and switch back on in a few days. I have used the passenger window from both drivers and passengers switch numerous times and it works perfectly. Mysterious ???

But, as we say, "if it works don't fix it"
