We can only open windows using the switches on the drivers door. Need ideas.
The window ‘‘lockout’’ isn’t a lock per-se’ but a circuit disconnect switch.
The see if the switch is the fault, jump the circuit at the plug …as if the switch is ‘on’ , and see if the windows work now.
If that works , either replace the switch or leave the circuit pemanently connected to work all the time.
I trust you’ve checked fuses.
Is there a switch for the window lock out feature? bypass the switch and see if they work. If not check in the door jamb of the rear doors for a child safety switch.
