Yes | No A/C Cooling Fan not working

Hi all,

I'm having an issue with my cooling fan, it will not start. AC blows cold when car is running but when it stops, it is kind of blowing hot air. I was told not to use the AC while in idle, it could damage the ac compressor since fan is not working. Now, how can I check if fan is bad or just a relay?

Turn car on. Turn AC on. Unplug AC fan wire(located on main fan shield, passenger side) and than plug in. If fan will move a bit- relay is good, fan- blown.
