Default howto disable A/C compressor in winter ?

Hi all,

The a/c compressor of our 2002 Ram is activated when we put the blower selector to blow towards the windshield. Even when the a/c switch is not pressed.

Is there an easy way to disable the a/c compressor permanently ?
Like removing a fuse orso

Because I dont like the a/c running in winter when its freesing.

regards,
Bart

Why, it comes on for a reason to remove moisture from the air for your defrost to work properly. If you disable it you will end up with frost/condensation on the inside of the windshield which is a major PITA. Unless it dosen't get that cold where you live ? I you really want to disable it just disconnect the wire to the coil on the compressor, If would not fool around with the fuses.

An other reason is that there are other ac issues (doesnt cool much, condensor fan broken) and I dont want to ruin the compressor itself. I was told that they have a hard time in winter conditions.

Of course this is only temp. untill it all gets fixed.

Annyway, thnx fir the tip

I agree, wouldn't disconnect it unless you absolutely have to, but you can either unplug it as suggested or get a shorter belt and bypass the compressor altogether, again only a temporary fix, not recommended for long term use. I don't see where the compressor works any harder in winter than in summer since it's going to cycle in more than just A/C mode but I had a similar problem not long ago and didn't run anything and in my climate, like Rans said, the condensation was a pita to deal with while driving.

^^^^ I agree if it's not working properly it would be best to simply unplug it to ensure you don't loose the compressor.

By buying the belt you should ALSO gain a lil MPG because you are creating less resistance on motor by eliminating ac compressor

a little update: In stead of disconecting the plug on the compressor itself I removed its fuse from the fusebox. Dident like the loose wires in the engine compartement.
An other belt seems a bit to much since the A/C will be fixed at the end of the story ...

Thnx for the help and happy newyear !

I was told by a mechanic that the a/c compressor should be run for a short while each week, keeps the O rings from drying out

Pulling the fuse would be the easiest way, then you could put it back in & run it for 10 or 15 minutes, when you remember to run it, to save the O rings
