max a/c question

[chaddiesel]

what is the difference between Max A/C and just A/C?
the only thing that I can notice is that the blower motor seems to work a little harder.

Max AC takes it's air from the inside of the cab.

Regular AC takes it from the outside.

There is a mod for Ford PSD trucks made before 2003 (I think that is the year) that helps get you cooler air when you select max AC. Made a noticeable difference with mine. Look here . Bob is a class act.

FWIW,

MAX A/C recirculates, plain A/C takes in fresh air.

thanks, on the dieselsite upgrade - where do you hook the vacuum line up to?

Inside the cab on the passenger side up under the dash.

will there be other vacuum lines to look for?

No that is the only hookup as far as vacuum lines. If I remember right you splice it into a heater hose right by your fuel filter.

Believe me, it is really easy if I can do it.

Fill out your sig line so everyone knows what year truck and motor you have.
Helps others help you when you have a question or a problem.

Welcome to SDD,

There are a couple of vacuum lines you can tie into. Im using the one that comes out of the vacuum bottle under the hood. Its ALWAYS on, so my heatercore is 100% turned OFF at all times.

That link has the parts and pictures of the do it yourself version.

Yeah, it is pretty easy, the hardest part is fishing the hose through the plug in the firewall. It makes a noticable differince though. Mine needed freon also and now it is an icebox. I can't handle it on MAX for very long.
