first off welcome to fte... what kind of rig? could be a wire to heater getting pinched or pulled by throttle linkage have you followed wires from switch to fan? fan has to be getting voltage from a 12v. source, so keep it simple to start with and look for bare wires touching.

I would also like to welcome you. If the following do not help, others will be along soon more knowledgeable than me.
Is there oil in the air box underneath the air filter? Is oil floating in top of radiator after sitting overnight?
IMO, I would be very hesitant going to 20W-50, but that has been discussed at length here before. Look above to Forums, then Search for tons of good info.

I'll second the suggestion to check the breather filter in the bottom of the air cleaner box. A soaked breather is a sign of serious loss of oil control around the rings and valve seals. PCV valve could be part of the problem as well. It's not easy to get to either as it is buried in the valve cover UNDER the upper intake plenum on the passenger side of the engine.
As for the blower fan cutting out, I have one question... can you MAKE this happen with any regularity and with the fan at any speed? Answer this and I may have more in depth suggestions for the cure.

Ahh my mistake... I misread it. Thought it was cutting out not coming on. Now that I have severed my rectal-cranial bond, I can say that the guys have you pointed in the right direction... wiring issues more likely under the dash than anywhere unless you have an errant power feed wire flopping around out near the blower motor under the hood.

The secondary filter (under the air filter) is the breather. Before assuming you have a more serious problem, replace it and clean up the crud in the bottom of the box. Replace the PCV valve and keep an eye on it for a week. If the crud and oil returns in short order, you need to consider the possibility that you are losing oil control inside the engine. I know it's not something anyone ever wants to admit but rebuilding is often the only certain cure. But then if it's consuming a quart a week you will save money in oil by fixing it.

Yes, disconnect the hose to the little filter in the air box. Crank the engine, lay a small piece a paper over the hose and the PCV system vacuum should hold the paper there at idle. If not, replace the PCV valve.
BTW I saw a mechanic laying over the top of a lifted, F-250 big tires diesel the other day using a great item. I don't know what it is called but it is small extension ladder design with a padded platform attached to the top which cantelevered over the engine. Nothing touched the truck except the mechanic's wrench in his hand. NEAT! and comfortable.
