I hear ya RedFish...the drivers window goes up and down more than a $20 prostitute! I'm not sure but it might have been you that I talked to a while back about this....But someone said I could weld teeth back onto that gear...but as of yet I haven't found anyone close that could do it (besides a high $$$ pro) And I don't have the welding skills to to attempt it myself....so my only other options are to find a "decent" used one or replace the whole door!
I'm repeating myself again.
There is no such thing as a good used , 30 year old, drivers window regulater in this "drive-thru" world we live in.
These regulaters are repairable though.
