New to the forum here, so thanks in advance for advice you guys can offer me. I recently purchased a 2015 F150 S/C 4x4 XLT, with 2.7. The truck was optioned with the electric rear sliding window, which is awesome, but continues to have a problem. After the truck warms up, the window will
Not open anymore. The dealer has replaced the switch, and also the motor, and still the same problem. When you first get in the truck (when it's cold) it works, but after about 5-8 mins of driving it will not open. When I click the switch to close it (in its closed state) you can hear the motor clicking back there, but trying to open it does nothing? Any ideas or advice?

Thanks
