Bring the vehicle to a certified HVAC technican as soon as possible.
Its hard to say whats causing this without putting a set of gauges on the a/c lines to determine whether its a leak,restriction, mechanical or electrical problem.

My ac runs fine when i turn my car on but then when i accelerate it starts blowing warm air


check heat exchanger . It is a little radiator for the AC to vent the heat away from the AC system under the bonnet.

Heater not blowing hot air in cabin


Check the coolant level. Check for leaks. Next would be clogged heater core(doubt that 2004) next would be the water pump. Kind of doubt that also, 2004. But if you have leaks?

AC unit is blowing both cold and warm mixing as if


Sounds to me like you've got a stuck door. One of the doors in the air ducts isn't closing/opening all the way. Possibly stuck or possibly a vacuum leak or disconnected/broken vacuum hose. Only way to know is to pull the dash apart. Sucks but gotta be done.

My AC was running fine before winter, now it only blows air.


If the system is working properly and you are only getting warm air, there are 2 common causes.

1.Check the air mix door motor and wiring.

2. There could be a leak in the AC system. No refrigerant means no air conditioning.
