123 window lift motor?

[Hank Fisher]

Hello Forum.

After a mere 344,000 miles my 1985 300D seems to be blowing lift motor circuit fuses when I try to raise or lower the driver's window.

After the first fuse blew, I lubed the regulator linkage with white lithium grease. It worked for about two or three weeks, and then blew the second fuse. Then the third one blew immediately after it was installed and switched on.

Now I am thinking that I may have a worn out lift motor. But, to tell the truth, I don't know if that is really the problem or not.

Have any of you been through this problem? Any tips on correcting the problem? BTW, the part does not seem abundantly available in the places I have looked online. If I cannot find the motor, is it a reasonable and do-able thing to convert it to a hand-crank window lifter? Inasmuch as I intend to drive this old car clean into the ground, such a thing is not beneath my dignity. After all, it still drives just like a Mercedes.

Thanks for reading this, and for your expertise.
