Default 2003 4.7L - removing A/C

My air conditioning compressor is about to die. I can count on 1 hand the number of times I've used AC in the 2.5 years I've owned it (Canadian ), so I'm wondering if Dodge makes a blank pulley bracket so I can just remove the compressor and be done with it.

Otherwise, its time to get creative, because I'm not shelling out $1200+ for something I hardly use.

If anyone knows of such a part, or has ideas, let me know...

I may be wrong, but doesn't the compressor still need to cycle when using your heat to remove condensation in the air? I'm not sure about the pulley, someone may chime in on that.

Not sure on the 03, or how the 4.7 is configured, but when the compressor on my 97 1500 went, I just measured the belt size without it in there, went to the parts shop, and found a belt that would work, and just ran the belt under the AC pully instead of over it.

Don't know about the regular heat, but with the defrost it does for sure.

Hmm, just looked at the belt routing in the FSM, thinking this may be the ticket, providing there's nothing poking out from the engine where the belt would have to go. Thanks

Still wondering if there's a a/c delete bracket though, not finding much in the FSM about it though, which could be explained by the "cycling under heat/defrost" comment above. That would make sense as to why it wore out, I have a short commute that is often with defrost running in the winter...

I know in fords, you can buy opposite tensiors to get rid of the compressor.. Trying searching for that. Or go to a scrap yard, and just pull one. You don't use the ac anyway, your pretty much just doing it for the clutch that's in theré

yep, the defroster uses it.
I had an exploder and the same thing happened to me. I just unplugged it, tapped the plug-in and let it free spin. Doesnt hurt anything, you just wont have dry air blasting in.
Oh also when you're using the defroster without it plugged in it will rev higher since its not turning the compressor but thinks it is.
Hope that makes sense, i dont know of a better way without replacing it.
BTW i live in Minnesota where AC isnt as necessary either

Do realize that on any vehicle from the last 20 years, the AC compressor disengages at full throttle. You won't gain any power by removing it.
