Window motor and regulator track

[Puddin]

Ok so I picked up a 1979 cutlass
previous owner put in what I thought were 1980 doors with power windows
however after purchasing wrong motor and research I have a 1977 window motor and window track. It’s been a pain. Still window won’t go up or sometimes very slow. The rollers and track are old the center spring is missing which I think is suppose to help window go up

my question is are power window tracks interchangeable between years ?

I see the 1980s motors are way cheaper and I see some sets of motors and window tracks sold together as a combo
not sure however if you can put a new set of window regulators and motors on various years


any experience with this ?

Sorry im not a track /parts years expert, But some common sense to me things could help here..
If you look at the typical home garage door system for example. there is some sort of counterbalancing spring system taylored to the weight of the door. Otherwise any lift motor wouldn't work at all or for long .. So same for the return spring, its like you pulling up on the glass Huge difference..
As far as the old tracks, old grease gets sticky as fuh. clean out old tracks and rollers and lube with lithium grease or something appropriate for both the metal and plastic rollers.. Can be another huge difference.
Window switches, they have large contacts inside to run big current as opposed to new sh*t having micro wiring. Snap em out of panel, snap em apart clean contacts and reassemble. Near free cost.
I think I remember the older motors being more powerful. probably best stick with them , and search repair options for track rollers if cleaning them dont cut it. May be able to drill rivets and bolt some other roller in there with like # 6 or 8 screw and nut with loctite. Maybe even hardware store shower door rollers if i remember right.
Thats my answer without answering your main question . should help.

You are right. That spring is probably the main cause.
I’ll ad it to My winter project list

dont forget the other details i mentioned. its a system. inadequate voltage from dirty switch with possibly dirty track or not free rollers wont cut it. Im a door and window guy at day job Not car doors, but whatever, helped people with them also.
