Hi. Actually this is not a bad job provided that you purchase the motor and track assembly as opposed to the motor alone. Any auto parts store will have what you need. You begin by removing the interior door panel. If you break a few of the clips do not dispair as all auto parts stores carry them. The parts you need are all model specific, including the glass. That said, also call your insurance company as most folks have complete glass coverage. J.

poss window regulator failure.rec replacing window motor and regulator as an assembly.dorman and cardone make these parts and are fairly inexpensive.

THE DOOR CATCH MUST BE REPLACED. THIS IS DONE BY REMOVING THE INSIDE PANEL AND REMOVING THE THREE TORX BIT BOLTS FROM THE OUTSIDE OF THE DOOR THAT HOLD THE CATCH IN PLACE. I HOPE THIS HELPS. PLEASE FEEL FREE TO KEEP ME POSTED. THANKS FOR USING FIX-YA. GOOD LUCK

you should first remove the door panel and then you will have access to everything in side the door

I had the same problem - driver side fine, passenger side front not working/slow or the back seat. You need to replace the window motor on the passenger side. Yes, there are two motors. It's pretty simple if you are handy with some tools. The hardest part is getting the 4 mounts that hold the window motor to the door off. The are factory riveted to the door, so I had to grind the outsides off and tap them out. Just watch the spring lever that holds the window bar for going up and down. I didn't pay attention and it snapped back - nearly broke my thumb.

Sounds like you have a wiring issue going on with one thing and the other has to do with the door itself

When removing the door panel, you need to remove all of the screws first. Then pull the door panel off. There should be screws around the edges or the door panel, and 1-2 screw on the door handle(on the inside). Then pop the door panel off, if the blazer has electric windows and locks you have to disconect them first, if it doesnt have power locks and windows, you have to take the window crank off,there should be a screw in the center of that. Unscrew the door lock and pull up. If it doesnt have them locks then you have to disconect it from inside the door panel

try checking for a headlight harness that belongs to the 89 and match it, or look for one online. Conversions can change the harness sometimes. You don't have to cut any wires. If you cut wires, sometimes you will have a bigger problem than you thought.
