Question

i have a 93 740i, i punched the drivers side console switch and the window went down never would come back up. i replaced the motor and ordered a switch, but later probed the console lugs with a grounded test lite and all the windows worked except the drivers. this leads me to believe it is not the switch. what am i overlooking?

Accepted Answer

Hello pm 1899m You might want to check your ground for the drivers window for the switch. You say you have power but how is the ground? Let me know your findings. You may still have a defective switch. Thanks

Answer

The ground for the switch should be a solid brown wire it may have one for each window. Any chance that a soda or coffee was spilled on the switch?

no chance on the soda theory. i appreciate your input, but this only verifies what i already knew.-that i have a problem but no solution.
