Reason I ask, (RB also asked this earlier but seems to have been missed) is if you can hear any growling (or something like gears getting stuck) coming from the front.

Try this:

Roll down drivers window, get out & close door.
Standing outside the X, turn the key to pos 2 (the position the key returns to after cranking), and then listen carefully to the sound the lights make. You should be able to hear the motors when they move (a slight hum). It also helps to turn off the HVAC and radio as well....of course if you HAVE to start the truck this isn't going to work. But, any growling usually indicates either the motor is toast or something is getting hung up/jammed.
