I was checking my 03 Exp's AC temp the other day. On a warm day (80's), the temp was cycling back and forth between 40 and maybe 47 degrees. It switched fairly quickly. When I reved the engine (it was in park by the way), the temp went quite low, like down to 33 degrees or so (I suppose due to the increased cooling of the fan and the faster compressor speed). These measurements made with the temp control to full cool, and normal AC (not max ac).

Anyhow, does this behavior sound about right? I have no complaints about coolness just wondering if it is in the zone.

 

my runs at 40

 

My 97 would run between 37*-40*!

 

Just remember as it gets warmer that you have a lot more glass than us F150 guys do, so when it gets in the 90s you won't be as cool as the regular cabs or the supercabs.
