I found the manual but only glanced at it, it should explain what you need to do;

Check wiring to motor and it should read around 12v. (digital multimeter) unplug motor and check resistance at motor. It should read something and if not the motor is dead.

check all wires to starter motor for bad earth.....make sure power reaching starter motor.....check starter motor isnt stuck

No, it isn't an ignition issue.

Check power to the starter motor solenoid.
If this is getting power when cranking, then the issue is with the starter motor solenoid or starter motor. Replace.

Hi,
The 'stalk' that controls all these functions is faulty. Your truck SHOULD still be under warranty...Take it in.

GL,

Someone will need to check the fuse for the blower, then the blower motor and the resistor.

I'm sorry but you have this posted in the wrong product category. Please re-post the question in the proper category This is the car and truck problem category

have you calibrated those plugs well ? .050 inch its the gap calibration for that type.

I am guessing that you already suspect the starter motor. If the battery is fully charged and the car won't crank over that could be the problem. You could try jumping across the starter solenoid first, if you can get to it and see if maybe it is just the solenoid. You could take the starter to a place like AutoZone and they can test it for you.
