Any idea about how to replace the window motor and regulator?

If it has no side-impact bags, no worry. But, you may wanna disconnect battery until you get in there. Often the original motor is held in with rivets--cut 'em off w/a chisel or dremel grinder. Replace new motor with bolts & nuts. Put merthiolate on cut hands--bandage the more severe cuts:). If you're careful, you can do it w/o cuts, but is awfully sharp in there in that narrow space with so much exposed metal edges. BEFORE you tear into it, while holding the switch in the direction that should operate the glass, bump along the door panel with your (wife's?)fist--often, brushes will stick and break loose from the banging and continue to work for who knows how long? HTH & good luck....sdlomi

I had a window control unit go bad on two of the 89 Accords we owned. Caused the same thing you have happening. It is a printed circuit in a plastic box the size of a pack of cigs located behind the left front door liner. Factory tech manual shows how to diagnose. Cost twenty bucks at the junk yard. bob

pull the door panel, then take out the 2 bolts that hold the glass to the regulator, take the window out of the door. now pull the 4 bolts from the reg. and the 3 from the motor , disconnect the motor harness and pull the whole mess out. the control unit on that car is in the master switch
