Blower fan motor quit working, it didnt show signs of going out just stopped. Fuse appears to be good are there other fuses or relays that can go bad and cause this, thanks

Check for voltage on the dark green wire for the fan motor. If it's missing, suspect the ignition switch or fuse number 1, a 30 amp.

Measure for voltage on the black / tan wire when the connector is still plugged in. If you find full battery voltage, suspect a defective resistor assembly or heater fan switch.

I know that this truck has had issues with the ignition, previous owner even had a steering colum in the bed I think he was going to replace the whole column. If it is the ignition swith how hard of a job is this, is it something that the layman can do or should it be taken to a mechanic? Thanks for your reply on previous question.

Don't jump the gun without testing for voltage first. Normally if the ignition switch is the problem, other things like the radio and power windows also won't work.

Replacing the switch isn't real hard but you must also look at the terminals in the electrical connector. If any are overheated, they can be cut out of the connector and replaced individually. Also cut off about 4 inches of the wire which will be hardened and impossible to soldered to. Splice in new pieces of wire. We can cover that in more detail if it becomes necessary.

I will attempt to check these as soon as I can, living in norther Minnesota right now, about 24 below zero, hard to work on the vehicle. But as soon as we get a warm up lets say 25 or 30 degrees, I will try out your advice. I'm not the best at mechanics and electronics but will give it a shot, I appreciate all the help, thanks so much.

Very sorry to hear of your temperatures. I'm in the middle of Wisconsin and the cold air really makes my asthma act up. I'm just hibernating in the house waiting for spring!
