We recently started cooling off allot, plus the typical NW rain, went to run the truck found out no defoggers. Lever wouldn't budge, reading the forums, probably a bent cable... nuts. Ran the truck from cold, the heater core hose was warm (coolant flowing) while the main radiator hose was cool, a good sign the thermostat was Ok. no heat out the vents... Tore the dash apart, not a terrible thing to do, lots of screws and pretty straight forward. Found the bent cable, also found, watching all the dampers, my truck blocks heat out the vents, heat only goes floor and windshield. My truck also has AC. Just surprised no vent heat. I was able to straighten the cable and it still works. Tried it several times. We will see how long it lasts, probably not long from the reports others have left. In the mean time I will search for a replacement. I don't think I had to remove the whole dash (hindsight), as most of the controls you can get access to through just the front pieces, but I would still need to drop the steering wheel, but that is just 4 bolts.
