They put freon in my car and it still blows out hot are the compress works and all that what else can it be

Low on freon. It needs to put on a set of gauges at minimum to check. Just adding freon, does't always fix the problem. To much freon, you will start blowing seals or lines.

The guage needs to read between 35/40 psi.. If its much higher you may be overfull, this causes it to not cool.. Fix by letting some freon out, then top it back to needed pressure.. If pressure is correct, it would be a clog in the system.. Usually an orafice tube or accumulator..good luck!

over filling it was a big mistake, so was guessing.
the freon is added by weight, from empty. not volume.
if the compressor spins, and no cold air , then its a big problem
the only tiny problem to cause this would be leaves packed in evaporator coil. (deep inside air box in cab)
take it to a shop before you damage the compression and fill the whole
thing full of metal chucks wrecking everything, at once $$$$
do not let the compressor run, if it dont get cold. do not.
get it serviced.

Make sure your blend door is closing all the way and that the actuator actually works.

just some suggestons.check freon make sure its got enough.make sure wire conn.is good on compressor.it does have a pressure censor on the low pressure side.located on the line u put freon in.on most cars.or u might have a bad thermostat.some ideals to start at.

if full off freon. check system for a leak. that is the most logical solution to this problem.

did you touch any wiring ??possibly a loose connection? a/c pump clutch???,anyway you wont be spending any money putting it right........good.

Most likely the freon has leaked from the system. Replacing it is a fairly simple process, but finding and repairing the leak is expensive (labor wise). Plus, in the States, federal law prohibits non-licensed personnel from working with freon and it's descendants. Find a good AC service shop and get an estimate--you may not need that AC air as much as you thought! Good luck!

If putting freon in made the a/c stay cold for 4 days then you need to have the system checked for a leak

check cooling fan operation while ac on.If fan is working proper,will probably have stuck exspantion valve.
