Can I make it so my A/C does NOT come on whenever I use defrost?

That figures...I just want to completely control WHEN my A/C comes on. I do run it regularly to keep everything working properly, but I don't like for it to come on every...single...time...I use defrost. I'm aware that it's very effective, but that doesn't mean I have to like/want it, right? Maybe I'll just remove the A/C fuse and replace it when I use the air. Thx guys.

Uhhh...I'm in MN, where it rains often and windshields fog regularly. Anyway, I'll just remove the A/C fuse and keep it that way the majority of the time (as I don't like A/C and turn it on only to ensure everything is working).

Did this guy even read what we posted about needing the compressor to properly & quickly clear foged up windows?
And the kick in the a$$ is the fact that he even lives in a wet area.
Your defoger wount work if you don't let the A/C do it's job and remove the moisture from the air. Not being able to see out of extreamly fogged up windows on wet rainy days makes driving both unsafe and not fun. So I gotta say......

Ha...I live in Seattle where it's 35-45 degrees and raining 100+ days in a row through the winter. (The summers are 70-80 and sunny every day however 
)
I don't even use my defrost that much. If it really bugs you, then toughen up a bit and crack a window. Also, they are correct in that not using the A/C with defrost will not work very well at all.

To eliminate fogging, you only need to raise the temperature of the glass above the dewpoint of the surrounding air. That only takes a warm engine.
Granted it does not do it nearly as quickly as "a/c-dried" air but it is still effective.
I guess it all depends on what you are used to.

Listen to this guy. I agree entirely. I have too read that running the AC once a month or so prevents the AC hoses from drying up and cracking.
If running the compressor freaks you out, though... you can just try the old old method of wiping the winshield every few minutes with a rag.

An alternative is to select the mix mode (windshield defrost + feet vent) and that will not force the A/C compressor to come on. Use this with outside air only as recirc will most definitely trap humidity inside and make the windows really foggy.
As previous posts mentioned, running A/C compressor in the winter time helps lubricate the A/C system and prevents seals from drying out and causing increased refridgerant loss.
I do both of the above, depending on how many people I have in the car and when was the last time I had run the compressor.

Alright all you haters and insultaholics...I pulled the A/C fuse and experimented during VERY wet weather. Well whaddya' know? The windshield and side windows cleared almost immediately (despite multiple comments to the contrary)...think I'll just leave it that way and replace the fuse only on those rare occasions that call for air. Oh, and Chefosaurus...yes, I am a masochist...that's why I wrench on cars.

csb, it will work in some conditions with just you or maybe another passenger. If you have passengers in your car or in the winter months, there will be too much moisture that fresh air will not be able to handle.
Moisture from breath will quickly fog up the inside, especially the back door and rear window. This is when you will need A/C to keep the moisture content low inside the car.
