Ya it's a pretty big issue. Not everyone's is quite that bad, I know mines not. But most every time someone takes it into ford they claim 30 degrees less than outside temp is "within spec".

First is on normal ac about 42 degrees





Next is Max ac right at 40 degrees

Thanks for posting that. Huh, I guess first I'll confirm temp accuracy of the K type thermocouple I was using. I think I have a probe like your using in the kitchen...Nope, found it in the barbecue. Kinda fairy, says Pampered Chef on it. Oh well, I'll see if it works.

Anyway, if it's not blowing as cold as it should, do I just recharge the system? Or is there more to it than that??

I'll leave it alone, don't want to take any chances if there's any.

I'm not a pro on ac, but I believe if it's low the rule of thumb is to figure out where the leak is since it's a sealed system before you recharge it, or you are just wasting money as it will leak out again.

I don't think it leaks. Well, I've never touched the AC since I purchased the truck new in 98. If it does, it's a very slow one. It plugged up about a week ago, blew nothing but hot air. Fixed itself luckily, the drain was plugged. While I was checking it out it belched quite a bit of drainage to the ground, then it went cold again..whew, nothing major I hope. Guess I have to figure out a way to keep that drain clear.

That's flat impressive you've never had to touch it with as many miles as you have on there.

Lucky I guess. Truck was garaged most of its life (when it wasn't on the road), engine compartment never did get dirty. I sealed it off the best I could after I purchased it. Not tight, still circulates air when driving, just enough to keep the foreign matter away. So, that might of helped.

All of you and your properly working silly Air Conditioning, lol. My truck hates me right now.

My rule of thumb for road trips are, if I can't afford the tow bill home, then I don't have enough money, lol.

We've been taking my wife's Maxima on all the road trips lately and we'll be heading back to Michigan next week. :0) I don't get to hit the Dunes but at least it's a comfortable ride.

yes 70 degree a/c = not working very well at all.
should be right around 42, the temp cutout switch shuts compressor off at 38 deg. (i think)
even 50 wouldn't cut it for me

I have never heard 30 degrees less than ambient is within spec.
it should be just a couple degrees over the compressor cut out temp, which I believe is 38 degrees.
