I recently purchased this truck. The previous owner told me that the power windows do not work and he thought it was an electrical problem. I bought a new 30 amp circuit breaker, but it still does not work. Incidentally, the power locks on a different circuit rarely work. It seems that I have to wait for the circuit breaker to reset before that will work again. Do you think I have a short in the system affecting both circuits? What should I try next?
