Power Window Motor

[xjsjag]

Hi Group,
I just finished a repair job on my power window motor, but I know it won't last forever. I found out that whoever owned it previously had the damn thing "cobbed" together with electrical tape etc. I have an '89 and was wondering if any of you might know what other vehicles that motor might be from. The other side had a Delco part number but was unreadable. Knowing Lotus they probably got it from something very common. Thanks Kenny

There are some GM parts from the Australian Holden Commodore (V series). These fit the 89 Turbo Esprit with the addition of three simple mount spacers. There were also some Bosch numbers on them - numbers as follows:

RH 90 275 122 (680-65040-4)(Bosch 0130-821-175)
LH 90 275 121 (680-65039-0)(Bosch 680-165-039-000)

Kenny,

There is an outfit in Florida who will repair/rebuild the power window motors for about $100.

But, you are correct that the windows are another 'Lucas' engineered weak spot on these cars. A major part of the problem is that the window power circuit passes through the window switch. As this switch pits and carbonizes over time at the contact point, the current capacity of the switch decreases and so the window motors get progressively less amperage resulting in prematurely worn brushes on the motor.

There is a fix however. This involves wiring a relay into the circuit allowing the switch to work only as a switch for the relay eliminating the need for all the current to pass through the switch. It costs about $30 to do this conversion in readily available parts from any Radio Shack etc. Once converted, the motors, receiving full amperage current, work smartly and quickly and will last at least twice as long as they do in the existing circuit layout.

If you are interested in getting the procedure for doing this conversion, let me know and I will e-mail the procedure outlining the conversion step by step to you...Jim '85TE
