Ours is a 94 and had the typical regulator strip out problem. I think they used an off the shelf Chrysler power motor welded up to another brand's regulator.
Our window would just drop and skip. This was a few years back and I remember trying to find the original manufacturer with no luck. Someone on ebay had a new old stock unit for $500.00.
There was someone else who rebuilt the regulators but wanted the used one in exchange and it was still charging around 300.00 back in 2014/2015.
I wasn't going to gamble that much money on a crappy design anyway.
Did some internet searching and took a gamble with what looked like a workaround.
I found a mack truck manual regulator (Regulator Assy 25169077) and it fit almost perfectly. Had to drill a few holes wider for mounting onto the door frame if I remember correctly but no major modifications were needed.
The plastic door panel was just formed incorrectly to just slap on a manual crank handle so I bought a power window kit on ebay for 50.00. Came with two motors plastic gears, adapters, and everything needed to connect the manual regulator to the new motor setup.
It fits almost perfectly under the stock door panel but just sticks out ever so slightly under the armrest portion...no big deal. Had to drill a hole in the panel to accommodate the slightly wider gear setup. Covered it up with a small plastic cap glued on and you'd never know it wasn't an oem setup.
Now have a working power window again with an extra motor in case.
The manual regulator was 79.00. Motor kit 50.00. And much more reliable than the original setup.
