hey I have an 89 GXL and the drivers side switch broke. Also, yesterday the electrical part broke too!
I know that the S4 switch won't work with it, but if I also get the electronic part, will it work? Is it also gonna fit in the armrest?

thanks!

 

I put my S4 driver's switch in my S5 and it worked fine. So, I'd say "yes."

 

And I have done the opposite. I put my S5 driver's switch in my S4 and it worked fine for me aswell.

 

Cool! Thanks!

on this note, i have a 90 gtu...im pickin up a 88 gxl...i just about to post this too...so i can replace my manual windows with the power ones from the gxl? that is if i replace the armrests too? also what about the power locks? now to save posts....will the main cat fit too? i basically tore a hole in mine oh well...after im done with the stuff i swap (suspensions, brakes, ftp lenses, and possibly cat) i will have a 88gxl parts car up for sale or parting out...

If you end up using your s4 door panels, the s5 switch is deeper. I had to carve out some of the foam in the switch pocket to make room. The plugs match right up.
