Anyone have any ideas on how to fix window that wont go down or up. It happened with out any noticeable previous problems. You can hear the click noise in the button when you push up or down but no action to the window.

I ended up testing the power to the motor and found 12 volts so determine that motor was bad. Purchased a rebuilt motor from Oreilys and ended up damaging the regulatorcable in the process. returned to oreilys and got a credit on rebuilt and purchased a regulator/motor. Install of regultor/ motor was the way to go. Cost for parts and tax 109.00 dollars.
