Air conditioning failure

[musali]

my A/C blows hot air when im travelling on the highway, i was thinking it was the fan too.

I opened the hood, and turned on the a/c button on the console and hte fan did not start.

However, two or three days later, i parked the car, shut the car off and walked infront of the car on my way to work and i hear a fan moise blowing. Not sure if its the radiator fan or the aux fan. IT seemed to be the aux fan.

so im pretty lost as to what i should do next besides take it to the dealer.
