SOURCE: Hyundai sonata air conditioner trouble shooting

Most often this means the freon has gone down. You can add it yourself a lot cheaper if you are a little mechanically inclined by just buying a can of freon with a built-in gauge at Walmart or auto parts stores. Follow instructions on the can but be patient. It takes 10 to 30 minutes to add all of it. Or, a mechanic can do it. He will charge at least 40 to 80 bucks. If you or a mechanically inclined friend do it, less than $20.

SOURCE: air conditioner

check if the compressor is engaged...if not, check if there is refrigerant in your system...

there is a pressure switch that would de-activate ur compressor when low on refrigerant..

SOURCE: AC not blowing cold air

Most likely the A/C system needs to be recharged with freon.
Most shops charge under $50 for this service.

SOURCE: Hyndai Sonata air conditoning blower only works on high

I agree with 'motgor1258'... replace the blower resistor (it's actually a power transistor).

2001 sonata blows only hot air

First make sure the AC system is fully charged, with a gage hooked to the low pressure side the pressure reading should be 28-32 PSI. Also take note if the AC compressor is turning off and off continuously in short bursts, the indicates a low charge and if the charge is low you have a refrigerant leak somewhere. If that is all ok and system is not low on charge you may have a defective air temperature control blend door problem, either the door is sticking due to being warped or the actuator motor is defective or both, most times both are a problem. the part is only accessed by removing the entire dash assembly.

My air conditioner on my 2006 Hyundai Sonata runs for a couple of days and then blows a fuse. What causes the fuses to blow?

a bad relay will arc on the inside causing increased amp flow. Try replacing the ac relay. $23 for a compressor relay from This all depends on which fuse is blowing. a wire shorting to ground will just as easily blow a fuse.
