Sebring air conditioner

have an accredited ac shop as an ac cannot produce hot air only cold air so that means that the ac is not working (leaks low on gas etc). The hot air is from the heater in the car and the smell is probably wire overheating or the resistors are burning.

That's a tricky one. Sounds as though there may be a loose connection / dodgy fuse or even a charging fault. I assume the battery lamp is not glowing at all when the engine is running.

You need to stop using it immediately before you
cause some damage or more than you may already have
That is just common sense. It should not overheat or
be any different than it was in the past without problem

The car has to be checked over/diagnosed,tested,etc for
various issues to resolve

Borrow or Rent a car until resolved

No way to guess at the problem

You should have some type of codes avail even
if the check light isn't on,you need professional help
to get a start on resolving

The timing belt maybe worn & jumped or the head gasket
bad.

Over heating isn't usually a cheap repair unless the thermostat
sticks partially closed

The RPM moves around the car is 11 years old,so it may just
need a though going over

Timing Belt,O2 Sensors,Exhaust Converter,Spark Plugs
and such

If you depend on a repair shop to do things & don't
have the knowledge to request work done throughout
the year,then you run into a lack of proactive preventative
maintenance situation. Most things are simple looking
back, once resolved

It is in the low side AC compressor hose.

A mechanic would check for voltage at the ac compressor and the freon charge when the ac stops working.
If the compressor is cutting on and off the idle speed will change.

When AC light flashing that can be an indication that the compressor clutch is slipping,

ckeck your blower resistor and the connection

if the freon level is low the AC compressor will not turn on, you do not say whether or not the fan turns when the selector is placed on AC or heater etc.

see if that vehicle came without A/C. If so ck for the belt availability and see if it can be put od bypassing the compressor. At the least, disconnect the compressor clutch wirin g so the A/C will not function at all. until you can manage a the cost of a pump. Good luck, Ned

If only the AC indicator light is on but you are still getting warm air from the vents, this is not an issue.  Most newer cars run the AC compressor nearly all the time to prevent moisture accumulation inside the car.  Without the compressor running, your windows may steam up and hinder your visibility.
