Hello Everyone!

Great forum. Thanks for everyone for your posts.

I have a '08 Super Crew 5.4L. Great truck so far.

Quick question - if I pull the AC relay up front, it also disables the 4x4 control. Is there anyway I can have the defrostor without the ac compressor working all the time?

I used to pull the relay in my jeep and jimmy to save gas in the winter and run the ac every so often to keep moisture out of the system.

 

You could just unplug the ac clutch at the compressor.

 

that was going to be my last resort.

 

the AC runs during defrost for a reason.
With the AC running the air you will be blowing on the windshield will be dehumidified. Less humidity = less fogging
