Are all window in the 2006 Ford F-150 Crew Cab controlled by the main window switch?
When I push on the button on main switch, the dome light draws dim as if power is being pulled from something! None of my other windows along with the main driver side window won't work. All my wiring and relays are performing correctly. Do I need to replace the window motor/regulator?
Try replacing the battery to see if the battery terminals clean of corrosive, if not change the battery Fron another vehicle.... I owed an 2006 ford HardleyDavidson... If you continue having problems with it contact me at northernflavor@ aol. Com
It's most likely the switch. Think about a device that gets rained on, soft drinks spilled on, handles all the operations of all the windows and gets jarred continually by closing the door. The dimming lights is usually a sign that the motor is getting power (load) but unable to move the window. Nuff said - check the switch with a test light, pull the door panel and disconnect the motor and test the power supplied to it with a test light. Look inside the door to see if the regulator is stuck, bound or otherwise damaged. If the lights don't dim slightly with the motor unplugged, I'd say that you found your issue.
