Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
Hello, my name is***** of the time this is caused by a bad window motor. The motor itself fails and causes this to occur. The only way to truly verify this would be to test for voltage at the window motor while operating the switch. If it shows voltage then the motor is bad. If not then there is a voltage supply issue. It does sound like the motor itself though. If you need more help please let me know.
