2001 Dodge Dakota...
Recently, I had a standard flush done on my truck's AC system. Now,
when the AC's off, even if it's not particularly warm out, and the
truck's not warm, and the dial's all the way over to "as cold as it can"
if I turn the fans on we'll get warm/heated air out of the vents. This
didn't happen before it went into the shop. Other work was done at the
same time, but afaik it wouldn't have affected the AC/heat (tie rods,
Is it possible they screwed something up? What? These are Daimler
Chrysler folk, more used to Jeeps, as they're Australian and Dakotas
aren't made here.
I like the shop, and don't want to go in with this unless there's a real
possibility they've made a mistake.
Why did you even have it flushed??? First thing to do is to have the
charge level checked and see if compressor is cycling properly. A A/C
is pretty generic in function so they do not have to be model trained
here, only A/C trained.
Before you jump to conclusions, I suspect JMC had the "cooling system"
flushed which is sometimes confused by owners with the A/C system. They are
two separate systems. Typically, a cooling system flush won't affect the
A/C system unless a vacuum line was disturbed inadvertently. The control
system is operated by engine vacuum and if a line was disturbed or broken it
could cause this symptom. I recommend returning to the shop and mention
that this prob was not occurring prior to their service and ask 'em to check
it out. A reputable shop won't mind at all since most shops recognize that
there is a possibility of an error on their part.

Mike, thank you. It was indeed a cooling system flush. Just don't know
my terminology. The system hasn't been used hard for the last three
years, and will be used very hard this year. It wasn't particularly
warm in the UK, and gets very, very hot here.
It's mostly been the spouse that's been complaining. My personal
opinion is it just *seems* to be a problem, because in the UK we
normally had it on window only and heat, as they tended to fog up
quickly otherwise. Here, we're using the normal vents.
Please, forget I asked.
If the discharge temp is only slightly elevated above ambient, then this is
probably normal. The outside air comes in thru the cowl and is warmed by
the mass of the body and HVAC housing and seems to be heated. After driving
for a while the body mass and HVAC housing cool to near ambient and the
discharge temp is less noticeable.
Hope this helps!
BTW, ask anytime ;^)

There's a country singer (can't remember who though) who sings about
this, but for the life of me I can't remember who, or find the song.
Someone recent. Keep thinking it's George Strait, but can't find it
there either. ANyone know? He sings about the water pump being a quart
low, etc, and it'll be fixed for, oh, $800?
