Re: 3rd row vent windows work intermintanly
I'd bet it's either a loose electrical connection or the switch/window motors are on their way out. Electrical gremlins can be hard to pinpoint. In your case I'd get the voltage tested at each end while someone sits up front to run the switch. This will involve taking off some interior paneling but a couple hours of work should narrow down the problem.
