Window motor replacement

If the motor is bad on a 98 T/A do you have to use a rivet gun to mount the new one or does it come with a bolt kit?

directions state use rivets but you can use bolts in place of. Sorry, I can't remember the size.

The GM replacement motors come with bolts but some aftermarket kits come with bolts or pop rivets. Either will work so long as you make sure they fit the hole snugly. If you use bolts either use nuts with the nylon inserts or locktite to ensure they don't loosen. The motor produces some torque when operated. You don't want any play at the mounting points once you install the motor or over time it will shift and begin to expand the holes and then you will have to replace the mechanism as well. A motor will fit either side (right or left). Some GM and aftermarket replacements come with the motor already installed on a new mechanism. Motors with the mechanism are specific to right or left side. It is a bit more expensive but it you have any play in your mechanism already you might want to go this route.

also if your passenger window motor is slow or not going all the way up then you need to do/get the window fix for that.

It's a $35 (IIRC) kit that reroutes the hot wire. Long story but it makes it work properly and helps the motor last much longer.

I had replaced my window motors I believe twice in a 5 year period. The ones I got had come with bolts and nuts. Either put Loctite or use nuts with nylon. I would not use the rivets. I had put mine with bolts and never had an issue getting loose. I also recommend the wire kit for the passenger window.
