E28 window motors.

[Simufly]

Got these a while age intending to upgrade the very pedestrian front windows.
As the car has now gone to a new home, these are gathering dust (metaphorically speaking; they are well stored)
So anyone want them $65.00 each plus shipping.

Simon. Are they a common upgrade? I assume they improve the speed of raising/lowering of the windows? Do you by how much?

I’ll take them if you think they would improve NEW.

thanks, Michael

Modifying the Wiring Modifying the wiring to allow the existing switch to be used with the new 2 wire motor is actually much easier than you might expect. Essentially you need to provide a ground to the free connector on the drivers window switch, and you connect the blue and the green wires from

thanks Simon. But too complicated for me. I’ll pass for the moment. @slapshot - all yours if you’re still interested.

thanks, M.

Yours is a later car so does not have the sardine can motors so the upgrade is easier with no cutting.

Michael, there are a number of threads discussing this for late 73 & up window motor swaps. Regardless of whether you want to do it now, $65 & in-country is below market. If they didn’t sell to Slapshot, it’s a good idea to pick some up b/c you’ll likely need them at some point & they’re getting more scarce & expensive. Jay
