Ouch.. i know what you mean about the Florida heat.... Me being from the UK it feels like being in an oven when ever I am in Orlando (not that i have ever sat in an oven

)
I think your car needs a recharge personaly... I suffer the same problems myself when the gas runs out in the AC of my ES. Also best get a pressure check done so test for any leaks.. Also ask for a dye to be added to the gas.. then next time you go for a recharge you can get them to check for leaks as the dye will show under UV light.
