i was hoping someone could walk me through replacment of the right and left front window motors on a 1994 regal century. im pretty mechanically inclined, but dont know exactly what to look for, if i can figure oout how to remove the door panels without breaking them. thanks.

Br,
After doing one in my wifes Riviera, when the second one went bad I called the glass shop. They did it in no time and the price was very reasonable. The motors are riveted in place and you have to drill out the rivets and then try to install the new ones without destroying things. Also, as you mentioned...without some special tools it is real easy to damage the door panels. After 30 years or so of doing almost all my own work, I have finally realized that sometimes it's best to pay someone who has all the tools to do it easily. If you cant find a good glass shop in Rockville...call the guys at D&S glass in Waldorf and see if they can help you. They did my Riviera at my shop in the parking lot...took them about 30 minutes !
Hope this helps,

thanks a lot for the advice! i grew up in waldorf and know exactly the place you are talking about. what a coincidence, huh?

I just fixed my driver's door motor fairly easily.

I had to remove the door pannel first but the fix was easy after that.

The bottom of the motor is facing the forward part of the door bottom and with a mirror and plyers you can remove the plastic end in a few seconds. There are 3 twist tabs and it comes out. In that plastic end cap you have the end bearing and 2 brushes, one connected by an overcurrent temp strip. I soldered this over.

You have a 2 wire plug in the motor and the motor is not grounded. If you reverse the plug and push the up bottom it will go down so it is a reversable motor.

YOu also have a plastic circle opposite this plug with a hole in the center of it.

If you connect one prod of an ohm meter to one of the 2 terminals and the other is pushed in the hole you will get a direct short or a few ohms on the meter. That is the correct terminal to power the motor rotor to test it, if you get some ohms just put 12 volts across the rotor through this hole and correct terminal that has some ohms and the motor will run.

If it runs it is the high current protection strip that failed. I had this problem and soldered the strip and the motor worked.

Or you can go to a junk yard and pull off one of these end caps that work and install it on your motor which I also did later.

We are talking about an hour for removing and replacing the door pannel and 5 minutes for removing and replacing the motor end cap.

The only problem is keeping the brushes in the slots which can be done with a small drill bit through the plastic case holding each brush back in the slot.

Some of the older motor end caps have a set of contact points and a self resetting breaker. My 90 Lesabre has a current strip.
