Do I need a new power window motor?

If nothing at all happens when you try to operate your power window, the window motor may be at fault.

But just in case it's a dodgy switch, it's a good idea to isolate the window motor from the switch and apply 12V power from a different source. A spare car battery works well.

• First check that the associated fuse is intact and the power window child lock is off
• Remove inner door trim
• Locate & unplug power window motor from car
• 

• Apply 12V power directly to power lead of window motor
• 
• If window operates normally, your switch may be at fault
• If window does not operate, your power window motor may need replacing
• Power window motors that have a module or utilise a multi-pin harness style plug cannot be tested in this manner
• This information is supplied on the assumption that the power window regulator is in working order
