* Slaps forehead * So the A/C is not broken
 

Messing with my 03 4.4i yesterday and it got really warm, really quickly in the car (I was wearing a heavy outside jacket) and hit the 'Max AC' button on the auto climate control.

Nada...nothing....zip !

Hmmm... fiddled some more, regular AC works, everyhting else works but no max AC.

Ah well, perhaps I disturbed something when I removed the panel to add the aux input.

On a whim, I actually checked the manual and to my surprise found the following "Max AC function is in-operative if outside air temp is 41* or less"

Ahhhh... 38 * outside so it makes sense, most folks don't need max AC but there you have it, MAX AC shuts down at 41* or less ... we learn something everyday :rofl:

that's something i haven't heard

:thumbup:

Yeah, it shuts down when it get's cool. We had the guts behind the Max air switch replaced in our older (thankfully retired!) 4.4i a few months back - it cost $600 Cdn. Under a CPO warrany, also thankfully.

Thank you for this post.
You just saved me a headache.
My 01 3.0i had same thing happen over the past few days.
i was about to contact the dealership.
but now that I look back, its been below 41 all this time.
Thanks again.
