Hey! Twills made some really good points, and I know that Travis knows his stuff also, so either one of them are good sources, although, I have a much simpler and more to the point solution, but there is one thing, this will only HALF way solve your problem, but my suggestion is, since you dont need the A/C anyways, just disconnect the belt from the A/C pump, and take out the pulley, so that all that's left is the a/c pump with no belt or pulley to get in the way of the fan or anything, to get to the a/c belt, you first have to loosen the altenator adjustment bolt, loosen that belt, take it off, then loosen up the a/c belt, and guide it around the fan to get it off...then back the long bolt out all the way, as if you still needed to loosen up the a/c belt, until it comes out of the hub that the pulley spins on, and of course take off the lock nut on the front of the pulley, wallah, everything comes out, guide your altenator belt back around the fan, put it in the correct grooves, pull the altenator back, tighten down that bolt, and bam...no more a/c will blow! It's not as hard to do as this explanation is long...anyone that has ever changed a set of belts can do this..sorry though, I can't help you with bringing really warm air into the car though, good luck!
