Question about 2005 Hyundai Elantra
I have a 2005 Hyundai Elantra, and I have been having an issue with the A/C not always being cold. When I am driving on the freeway and they engine is running at higher RPM's the A/C work great and is cold. But when I am at stop signs or get into traffic on the freeway and I slow down the air from the A/C unit seems to be outside air temp or hotter. If anyone knows anything that would help that would be great. Thanks

I would suggest your Freon is getting low in your air conditioner. As the motor revs up it circulates but won't when the engine slows down. Get a mechanic to put a tester on it and should not cost a lot of money if that is all the trouble there is..

SOURCE: A/C hot and cold air....
Technical Information: When the engine overheats (goes above 220 to 230 degrees), the ECM (Engine Contro Module) will disable the AC (won't let the compressor engage). This is a safety feature of the EMS (Engine Management System) to reduce potential damage to the engine from an overheat condition. Check your coolant level in the radiator & reseviore -- Low coolant level can produce the symptom you describe -- if low, top them off. Inspect your radiator hoses/cooling system for any signs of leakage (crusty deposits of dried coolant). Wherever you find this, that's where it's leaking. If you don't find any signs of leakage, replace the thermostat (& gasket if required (as a precaution) anyway. When the engine overheats, both cooling fans should come ON HIGH! If they aren't/don't, something's wrong and you need to find the cause. Every two to three years the cooling system should be flushed and inspected to ensure proper operation/condition and system protection. Overheating can seriously damage the engine. $$$$. An ounce of prevention is worth a pound of cure.
