Check for power and ground control at plug to motor while operating switch. OR if you can access motor , apply battery voltage and ground to terminals reverse polarity as needed for up-down change. keep hands/fingers clear of moving parts! do NOT apply voltage for more than 1-2 seconds! Good luck. Wouldn't hurt to test ALL fuses first!.......
thanks that help alot
check voltage at pos+ conection on motor while engaging window switch you should see source voltage same at ground connection on motor. wait i may be wrong on this, lemme get back to ya...
