Kelly are you saying your heater/ A/C blower is not working ? sometimes they freeze up meaning they just lock up and won't spin. in that case it might fry the 4 speed switch next to the blower also.

now talking the clutch fan it is very easy, you had to of taken it off when you replaced the head gasket it has the belt the alt. is took too. I would not say it's bad unless the truck over heats.
PM me when you read this about what is not working.
