Try running the A/C while highway driving for awhile. If a car sits for a period of time or basic city driving is constant, the A/C will sometimes not be working at its best. If theres no noticeable change in temperature while highway driving, then yes, bring it in. The A/C unit may need to be recharged or it has a leak.3dee said:.......does anyone else have this problem? My R/T's a/c at the very best gives *cool* air. I've noticed since day 1. My 11 year old Mustang has never had the a/c recharged and it blows ice cold.
This will be on my dealer *fix* list.
It gets like that on the freeway because there's plenty of air passing over the condensor. Airflow is the key to soo many things in life.Brooksie1of1 said:mine isnt all that cold around town, like in traffic, but on the freeway... it gets ridiciously cold...
Don't take 40 degrees as the cutoff. I have Diesels that are blowing 32-35 constantly. It's all based on the effeciency of the system. But 40 isn't too damn bad for a four-banger.clockmaker said:I was just at the dealer last week and this was one of the things I had them look at. They said that the air went from blowing 92 degrees F down to 40 in a six mile drive. They said if it blows any colder than 40 the evaporator coil will freeze up, so they can't get it any better than it is. Their suggestion was to switch on the recirculate button when the air starts blowing cooler. This answer doesn't make me happy, but upon trying it out it seems to work better.
They are only environmentally correct because they needed something to BS everybody with. The real reason they changed to the crappy-new-stuff (not to mention that US citizens think anything & everything "new" must be better and more desirable) is because Dupont's patents ran out and they had to formulate a new product to hold the monopoly. Then they simply greased all their super-lobbyist, new laws were made and Dupont was back in business The new stuff is not any more environmentally friendly than the old stuff.karenh56 said:You really shouldn't compare the old style freon based air conditioning system with the new environmentally correct versions. It is like an apples and oranges comparison. The new refridgerants are not as good as the old systems. That is why on some new cars they use a more efficient windshield to make they AC more efficient (ever see the bronze windshields? - that is why they exist). Tinting the glass helps.

Oh... my AC seems to be running good... no problems.
Hmm, oh well. I still don't buy the "environmentally friendly" card they are playing and don't believe the old stuff is more harmful than the new stuff and think Dupont needs to clean up their act, be more responsible and become better stewards with their power, resources and influence. Will that happen? I doubt it. Can I do anything about it? Not much. But if I could I defiantly would and any little bit of power I have over them I'll use to my fullest extent to make things right.ewitz said:
Every week I hear somebody say “this whole R-12 retrofit debacle is happening just because DuPont’s patent on Freon ran out.” Think about that. Assuming it to be true, then for all these years DuPont would have to have been the only company manufacturing and selling R-12 (not!). And then, anticipating that they were going to lose control of the product, they chose to sabotage R-12 by getting the EPA to ban its existence.
Continuing this doomsday scenario, losing their monopoly on the auto refrigerant, they "invented" R-134a and miraculously got it universally accepted by the world as R-12's replacement. And they did this all the while knowing that they would somehow be able continue to monopolize sales of R-134a as well??? Doubtful!
Obviously those concepts are false. Along with DuPont, Atofina Chemicals (formerly Elf Atochem), Ineos Fluor (formerly ICI Klea) and Honeywell (formerly Allied Chemical and Allied-Signal) were all major vendors of R-12, and are today major suppliers of R-134a. The "other three" did not pay royalties to DuPont for their sales of R-12, and will not for R-134a.
