Power windows

Hello, I’m Pete from the Car Genius team at RepairPal. I’m sorry you’re dealing with this concern on your Chevrolet Express. On this model the power windows are controlled by a PWR window circuit breaker which is located in the fuse panel underneath the driver's seat. In some cases this circuit breaker can start to act up/fail which can create this concern. This can also be caused by an internal electrical fault with the driver side master window control switch. The passenger switch goes through the driver side switch itself so if the driver side switch starts to fail it can cause both switches to stop operating at the same time. High amperage draw from one of the window motors can cause the window circuit breaker to overheat which in turn will open up the circuit causing the loss of window controls until the circuit breaker has cooled down enough to reconnect to allow operation to continue. I recommend having all of these checked into/tested to help pinpoint which component is at fault so it can then be repaired properly from there.
