I need some advice regarding window motors on my '85. I can buy rebuilt motors for the right side for $60 from online auto parts sources. For some reason, the left side motors cost much more. In fact, no one stocks the drivers side motors, but I can send mine in to get rebuilt for $145. I can see supply and demand for in-stock units, but if I am sending mine in for rebuilding, why is it so much more? Is there a difference between the right and the left? Has anyone used these reman motors and are they better than buying used from 928intl? They want much more for a left, also.

Does anyone have experience with either of these options?

So to sum it up, I can get used or rebuilt for about the same money taking the half-off sale into account. Any advice is welcome.

Thanks.

You may be able to just clean them up, clean up corrosion and old grease (wax after 32 years).

I bought these new on ebay left and right on ebay 2 years ago. Excellent !! They are still selling them. No affiliation. Link below.

Thanks, guys. I may just buy one of these new units for the right side, which is dead, and try to clean up the drivers side motor, which is slow.

I will inquire about shipping from the UK on these, though I guess it will be high.

I would always try to repair them myself first, even if the motor appears "dead" (they rarely are). It is very easy to do - just remove the motor (not a hard job at all). You do not need to pull out the whole window regulator to do this. Look for threads on popping off the door panel, and you have access to the whole thing. Remove three (or 4 can't remember) bolts and slide the motor out. Take to bench then disassemble and clean thoroughly. Carefully pull out the copper winding, and clean the electrical contacts well (but carefully). You can use your favorite electrical cleaner in there as well. Re-install the winding into the housing with the spring contacts properly aligned. This is a bit fiddly, but very easy to do. Then, but that part back into the base, and re-grease the plastic gear in the top part of the motor, and reassemble. Test with a large 6 volt battery (or two strung together in series). It should spin freely. Reinstall and you are good to go. I have done this numerous times on my 78 and 86. If you need to buy another one, call 928 International. They sell used and rebuilt. I would not use any other source for these motors.

Also, I should mention, always test for power from the switch to the motor first, before tearing it all out. Sometimes, it is the switch, and not the motor. Switches can be fixed too. There are DIYs on this as well.

Thanks, Ed. I have the motor out, and it is uncooperative with juice attached. I think I will try giving it a good cleaning. I was concerned about buying a used motor and having the same problems due to the "new" motor being as old as the bad one.
