Today, I was heading to work and rolled my drivers side window down. It went down just fine but didn't want to roll back up. I think the motor is fine cause after pushing the button up SEVERAL times it finally went up. So it will roll down just fine just not up. I am thinking maybe a bad switch in the controls, all other windows go up and down just fine on those same controls. Any suggestions before I go buy parts that I don't need. Thanks again for all the help...
