Cooling system issues

[Hawk23]

So it's starting to warm up down here in Texas, so I've had to turn on the AC a few times. Every few minutes or so, there would be a hissing sound and the air would get all warm. A minute or so later it would kick back on and get cold again. While this happens, there seems to be a mini surging type thing going on with my motor. My amp meter drops to about 12 and then goes back up to 14 then 12 and so on. Anyhoo, I was sitting in a drive through and then the surging stops, the air got really warm, and my temp guage went from normal (just below the middle line) to into the red in about 10 seconds. Once i got driving again, the air got cold again and the temp dropped back to normal. I got home and popped the hood, no steam or anything, but the coolant overflow was bone dry. I'm taking her to a dealer tomorrow (have a warranty) but was wondering if anyone might know what the hell might be wrong with my car.

Condenser fan might not be working
AC Compresor might be going bad when it surges like that sometimes it interferes with the water pump during Idle.
Thermostat might be starting to get stuck.

the a/c system is low the voltage drop and the surge is from it kicking on

the a/c will work without water in the radiator but definitly keep it topped off

it was the fan motors and relays. All burnt out. $500 bucks, only half covered by warranty. anyhoo...
