Question about 2004 Hyundai Elantra

2005 Hyundai Elantra A/C

My air starts off working then gradually gets hotter blowing only hot air. I put freon in it and now it still doesnt work and it makes a funny noise, lurches at excelleration, and is over heating (gradually climbing until almost in red zone).

Could it be the thermostat?

Sounds like your A/C compressor has failed.
Thermostat only controls coolant going through engine - not the refrigerant in the A/C system.
The bad compressor is causing extra load on the engine and making it heat up.
Unplug the compressor and take a test drive.
If it is unplugged - the clutch will not engage.
see if it heats up - and report back with your findings.

Check to make sure that the engine cooling fan or fans are working. Sounds like there isn't any air flow through the condenser. Also it won't hurt to wash out the condenser and radiator.

you have moisture in the system this causes your expancion valve to freeze up an stop working, thats why it works for sort time and when it de-freezes stars working again. you need to do a EVAC & RECHARGE with a good AC service equipment, specially attention to pull vacumm por at least 20minutes so you get all moisture out of the system.
Good luck

My 2005 hyundai elantra wont start


Sounds to me like your charging system failed and you now have a dead battery.
You will likely need to replace your alternator.
