    Hi folks, I need hellllllllp!
    My 2006 quad cab limited just decided to not blow cab air anymore. It was working fine when I got home one night. Then going to work the next morning, I suddenly had no blower. It was only 19 degrees out so a little warm air would have been nice. Anyway, I have checked every fuse, and relay, they are all good. I replaced the resistor and still nothing. I have pulled the blower motor, put power to it and it purrs quietly like brand new. So, I guess I need a tutorial on how to check the harnesses. There is no evidence of any wear that I can see, all plugs are nice and clean. I have also noticed the A/C button light does not turn on, nor can I hear the A/C clutch kick on. If anyone out there has a clue as to what I can do and how to go about it
    Please fill me in.....
    Thanks

    Was this a random occurrence, or was there a recent repair or mod of some kind? Does sound like it's not getting power from the harness. Not sure how you checked the fuses or the relays, but swapping the offending fuses for new may be worth a shot, even if the old one "looks" ok. Any water intrusion into the cab? The windshield cowl mounting tabs tend to leak water. Check for damp carpet in the passenger footwell and kick panel. Another more remote explanation could be damage to one of the harnesses, by a rodent perhaps. The harness that plugs into the center console trim is a good place to start tracing the wires and looking for problems.

    Thanks, I will do my best. It sounds like one of those easier said than done things.

    Also if you pull straight out on the fan speed knob you’ll notice it’s a square. If the knob cracked it could be turning to a different speed while not actually turning the actual shaft it sits on. Easy way to check is pull it off and swap with one of the other two knobs
