my 2007 trailblazer is having problems with the rear windshield wiper. the fluid works when i hit the center button but the other "1, 2, and 3" settings dont work. how do i find out if its the switch or the motor itself that needs to be replaced? also should be able to read 12v on the connecter to the motor?
