confused 2000 F250 - Air stays on always

It doesn't matter where the switch is on the dash, the air conditioning is on in every setting but 'OFF'. Everything else works as it should. Is there a switch under the hood on the AC system to check?

Re: 2000 F250 - Air stays on always

Hey rs-mn,

I used to own a 2002 F150 XLT, and the air was always on. I know that Ford had issues with AC units on previous years when people didn't use them for an extended length on time, like long northern winters. So, to prevent the unit to stop working, they decided to have the unit always working.

Sounds weird? Sure does. Effective? Looks like it. Had the truck for 5 years and no issues with the AC.

Cheers!

Re: 2000 F250 - Air stays on always

In every vehicle I've owned, and own now, the A/C is only on if you have the control knob on the A/C settings (obviously), as well as ANY defrost setting. As mentioned, this is to keep the seals from drying out in the winter months and creating warranty problems.

I haven't heard anything but you might want to check with your dealer about a software update? I know it seems like a long shot, but the A/C compressor SHOULD not be on ALL the time. It's very inefficient.
