Arrived at location on 3/9/22 - The window opens and closes but sometimes it stops. Raised the window but still have the problem. Need new motor. Also, the cable pulley is a little wobbly. Need to replace that, as well. Will obtain parts and return. Returned to location on 3/28/22 - Removed old motor and pulley. Installed new. Turn on. Open/closed window 20 times. Open/closed ok with no problem. Customer tested. Back in service.
