Default why does my 2006 sequoia ac blow cold while driving but hot while in idle

We have had the clutch fan replaced and had Toyota add freon. Before we left
the dealership we had them put a thermostat in the vent cause it was still
blowing hot. It read 105. They "Toyota" say there is nothing more they can
do. Basically, when the car is at a stop light or stopped for more than 2-3
minutes, it blows as if the heater were on. But it blows really cold while
driving. Any advice would be great!!!

They put a thermometer in the vent, not a thermostat.

Without regard to the vehicle's motion, or the lack thereof, a thermometer
in the vents of an active AC system should show about 50 degrees F (or
lower).

Your dealer service department is a bunch of idiots.

I'm an idiot too, just to be fair. I have no clue what's wrong, but clearly
something is wrong.

I have a '95 Bronco in the drieway that was blowing warm the other day. I
repaired a broken (obviously broken) vaccum hose that operates the mixing
doors in the heater box, and put in two cans of refridgerant. Now the system
blows chunks of ice, so I'm not a complete idiot -- unlike your dealership
service department.

So this is a dealer that punishes its employees badly when they make
mistakes? Because they can hook up gauges and check the system
pressures in just a few minutes. Have them do just that, at no charge
to you, and make sure they write down the pressure readings on a
receipt. I think they put in the wrong amount of refrigerant because
modern systems like yours can be really fussy about the correct level,
and even old systems like mine will cool a lot worse if overfilled by
even 10%..

And if they really did put in Freon they deserve to be shot because
your system uses Suva R-134a, and there's no such thing as Freon
R-134a.

While you are correct freon and R134a are different products, it is common
that people use "freon" because that's the first term for refridgerant that
they learned. They also use Kleenex to blow their nose even though the box
clearly says that the tissues inside are not Kleenex at all.

The difference between Freon and Suva mattered in the case of someone
at work who had an old car with Freon R-12. He took it to a shop and
insisted that only Freon be used in his A/C, but they put in some Suva
R-134a "drop in" blend and ruined his A/C. He showed the judge the
receipt that said "Freon only" and some documentation about Freon
vs. Suva and quickly got compensation.

Yeah, yeah, yeah, I got all of that. You and I might not use "freon" in
place of R134a in a sentence, and surely not in a car, but my point is that
you opught not be so quick to call out somebody that 1.) never touches the
stuff, and 2.) might not know there is even a difference. Air conditioning
systems must have some form of refridgerant in them, and the term for which
is used doesn't matter to anybody but the guy that is in charge of not doing
it wrong.

Given the fact that it is next to impossible to even get R12 in the USA
anymore, and the person that brought this up has a car where the R12
fittings will not even fit his car, it's pretty safe to say that even though
they watched the tech put in freon, it was not freon at all but was R134a.

While you are correct freon and R134a are different products, it is
common that people use "freon" because that's the first term for
refridgerant that they learned. They also use Kleenex to blow their nose
