The motors are made by Nippon-Denso, but I think I heard somewhere that they have long been discontinued. FIRST has said you cannot directly contact the supplier for more. The motor was donated to FIRST (probably a surplus of old parts the company had lying around) and so no more are available for purchase.
I do not know what vehicle or model they belong to. It’s application is that of a power window motor; it’s not exactly made for strong, robust applications.
Unfortunately, we’re using it in a critical location too, but we’re only going to blow out one at a time
Just so everyone knows, the window motors in the 2003 kit were used in the 1986-1995 Ford Taurus and Mercury Sable. The left front and right rear motors are identical to each other and those provided in the kit. I hope this makes replacements a little easier to find.
