Hi all,
I'm thinking to step back my 1973 S1 from electric windows to manual windows due to intermittent problems and in order to simplify electrics.
Is it ok to find 4 manual windows regulators + handles or there are other things to look for?

 

Hi - Based on the parts manual, the only differentiation between manual and electric regulators is the regulator itself. There is no different window, track or anything else specified except a stiffener to keep the powerful electric motor from bending the inner door.

Being in the US I've never worked on a S1 with manual window regulators - more of our cars have electric versions - but I've seen alot of electric regulators and they mount the same way as the manual with the same hardware. It appears to be a direct swap.

Also just FYI the electric motors are GM parts. If you need motors Cadillacs, Buicks, Pontiacs etc... of the S1 era use the exact same motor. I used to own ALOT of late 60's and early 70's Caddys and have a pile of Caddy motors lying around. Just replaced the passenger side front of one of my 72 XJ6's with one.

 

Thank you for the feedback, Mike. Yes, I also checked the parts manual and was quite happy. Then, looking around the web seems that the thing is not so straightforward as I hoped, although the logic is with us. Hope that someone has seen both manual and electric doors or made the conversion in a way or another may give a direct opinion...
