So I greased both window tracks today. 3M makes a grease just for this as it turns out. Great stuff. Fixed the driver window tilt with just this. The passenger side is toast.
When I got the VX it was missing the lower window trim piece on the outside. No idea how long it had been missing. After trying the grease, and a new motor, and the roller bearing, the regulator is just done. There is a lot of rust on the cable, probably from the window trim missing for god knows how long.
Anyway, I ordered a new regulator from Isuzu parts center. Not too bad at $117 shipped.
One step at a time this VX is coming back from the brink...
