90 240sx driver window

[angelo]

thanks for the help last time. it works fine in the morning but in the afternoon it doesn't ,could the heat be affecting something its parked in the sunny parking lot?

ok, put your key to the ACC. mode and then try to roll up or down your window. if you hear a click and nothing is happening, its your WINDOW AMP REGULATOR. they go for like $75 from the dealership. this is a typical problem for most 240's

test to see if there are 12v at the motor(blue and green wire) when window is supposed to be moving. if there is, the motor is shot.
