Default PT Overheating at idle

2003 Dream Cruiser 2
Help! For the past week when I am idling for more than 10 minutes with my a/c on my car starts overheating. The fan kicks in at a high rate of speed but the car starts to overheat anyway.
The car cools down back to normal once it gets underway. Can this be a bad thermostat or any ideas here?
thanks!

What about the low speed fan. It should kick on any time the A/C is turned on, even when it's cool outside in the early morning.

Lets see, what's left.......
1. Air in the cooling system
2. Cracked head gasket (are you loosing any water?)
3. Bad thermostat
4. Water pump malfunction

hey there..
yep.. live in the jax beach area..new here from savannah ga..

let me go down your list:
Lets see, what's left.......
1. Air in the cooling system (sounds expensive)
2. Cracked head gasket (are you loosing any water?) No, I am not losing any water...
3. Bad thermostat .. could be.. if so, this will be my second one in 40,000 miles..
4. Water pump malfunction.. God, I hope not.. I had my first water pump replaced at 16,000 miles, the second one replaced when I replaced my timing belt at 78,000 miles (I currently have 109,000 on my car)...

I am going to find a 5 star dealership here in the jax area and hope that they do not rip me off. I have taken care of my PT with all scheduled maintenance done on it. I have also had my timing belt replaced (as mentioned above), A/T flushed, brakes flushed, twice the fuel injectors cleaned, tune-up, a/c maint. done, rotation of the tires every 6,000 miles and oil changes every 3,000 miles with Castor high miliage oil.
Anyway, I appreciate any further feedback from you... I did read that you said that issues like this are usually the fan (96% of the time)...I hope that this will not be the issue here...
thanks so much!

Air in the cooling system is probably the cheapest thing that could be wrong. There's an air bleeder valve right next to the thermostat.

It's a darn shame you had to shell out the $85 for them to get the air out.
