If you have ever driven in an ice storm (I have many times) then you know you want only heat on the windshield. A/C running totally kills the fuel economy. Another situation is cold rain -- with 100% humidity and cold air, I have had condensation form on the *outside* of the windshield while barely keeping the inside clear. Switching to "pure" heat works best in that situation, as well -- and the only way to get all the air flow on the defroster and not have any A/C involved -- is to pull the fuse.

I pulled mine a couple of years ago, and I have not missed it 99.8% of the time. For the few times when it would have helped, I just have to wait for the engine to warm up.
When you say you "pulled" yours, did you just disconnect the electrical connector going to the AC compressor?
