power window regulator
 

do s5 coupe window regulators fit s4 verts?

Not sure but one way you may be able to find out is to check mazdatrix.com IF they list the window regulator for coupe/vert or just 86-91 then it should work.

Absolutely NOT
 

Coup and Vert window regulators are entirely different.

No it does not. I learned it the hard way by buying vert regulator for my coupe.

Nope.

Your only hope is to buy a used one (that will also break someday soon), buy an expensive new one (some day it will break) or learn to rebuild the old one.

Sorry for the bad news. There is a how to in the Archive and there are a couple more floating around if you search. I used bicycle cables to rebuild mine and added a pully to replace the broken nylon guide. The broken guide is the reason most vert window regulators fail. For some reason, the passenger fails most often.:dunno:

ok, well mine arnt broke i just didnt want to sell it to somebody if it doesnt work.
thanks guys!
