My 2004 GMC Envoy SUV midgate window won't go up!! any ideas??? The switch is okay!!
Relay maybe .Doesn't look like a relay is involved for window . Looking at a wiring diagram an using a volt meter to test electrical circuit would be the way to find the problem . Do you know how to test automotive electrical circuits ? How to read a wiring diagram ?
Midgate Components
The midgate consists of the following components:
• Midgate window switch
• Midgate latch release switch
• Midgate window regulator
• Left midgate latch
• Right midgate latch
• Midgate latch relay
• Midgate 25-amp window regulator circuit breaker
• Midgate 15-amp latch relay circuit breaker
Midgate Window Control
The midgate window is controlled by the following:
• Midgate window switch
• Midgate 25-amp window regulator circuit breaker
Reading a little more from service repair manual i do see a relay , it's part of the window motor assembly . Could
possibly be the window regulator . You need to take midgate panel off an look inside . Test electric to the motor while in then .
Midgate Window Operation
When the midgate window switch is activated to Up, battery voltage is supplied to the coil of the midgate window up relay in the window motor, energizing the relay. When the window up relay is energized, the window is driven in the Up direction.
When the midgate window switch is activated to Down, battery voltage is supplied to the coil of the midgate window down relay in the window motor, energizing the relay. When the window down relay is energized, the window is driven in the Down direction.
