    Ok was driving & doing errands today, blower motor working good - no problems.
    Then after dropping stuff at home, got back in the truck & blower motor does not do anything.
    Checked the #4 fuse, even swapped it with another & still nothing.

    Im guessing its mot the switch or resistor.

    So is the motor gone??

    Its stupid cold outside so did not check power at the motor, so don't know it has power or not.

    I could be the motor is bad. I also had one truck where the ignition switch had melted some causing the blower not to work.

    Ok had the motor out & bearings are bad not it still works on bench, it just stops fast after power is off.

    so I hooked it back to the truck plug & it only works when I add power to the plug.

    So I think this Is a burnt ignition switch.

    Is it hard to replace the ignition switch

    I will also replace the fan since it on the out.

    Ignition switch & heater fan/motor.
    The switch was about what prices are on the net, but the heater motor was way more.

    All back together, the ignition switch is tight but works good.

    Did the exact thing last month. Except I changed the motor, then the resistor, then the control unit, and finally, after the dealer diagnosed it, I changed the ign. switch. They wanted over 500, including diagnose, and the ign. cable, which it didn't need.

    Ignition switch

    I had my blower motor go out then I replaced the fan motor and it is working but got a immediate. Dash light for engine could the ignition switch be bad too. It is giving me a p750 code and can't reset it.
