Power windows changed in 1996 240sx. The amp is in the main switch on the driver door. The wiring is simple. A 20 dollar digital multimeter is all you need. Im not sure if the amp in the main switch can be repaired like the other years. You can open up the main switch and clean with compressed air for cleaning computers.

Trouble-shooting guide:





The 1995 window amp appears to be compatible with 91-94. obviously, the 96-98 are not.

I know, I know old thread. So your saying that the amp is physically located inside of the driver's side window switch? If the amp goes bad, you have to replace the whole switch then?

yes, for the 96-98. 91-95 , no.

is there any way to bypass the window amp ?
