88 Avanti Convertible ------------- United Technologies unit: 4700724MO16WM 4336601 (aug 2007) Hi I also have a 1988 Avanti convert and just went throught the same thing. The pasenger rear wire frayed. I went through all the they came out of lebaron converts and other cars, don't waste your time. Even if you are so lucky to find what Avanti Motors used you would have to break the welds on the brackets they welded on so it would fit in the car, then reweld them on the one you found. I just got mine back from a company called Window Motor World inc out of Boone, NC 1-800-252-2649 ( windowmotorworld.net ) I had the regulator taken out and shipped. They replaced the motor with a newer one and replaced the cable with a thicker cable and guarantee it for 1 year. The cost for new motor, new cable and they payed shipping to me all for 150.00. They turned it around in one day. Save your time and energy and have these guys do it. As soon as winter comes I will send them the other side to have it done. (jeffgrohs@pacbell.net Aug 2007)
