Bill-SD, do you see water under your car on humid days if the engine and AC are running and you're parked for 10 minutes or longer? If so, chances are that the Evap case drain is not clogged.

It's been really hot not humid, but I haven't seem any dripping water. If it is clogged, about how much should it run to have it unclogged?

Unclogging is real easy. You have to find the rubber drain for the AC evaporator which is located on the passenger side of the firewall, on the same side of the firewall as the engine. No disassembly is required. Once you find the drain get an airgun if you have one and blow air into it. Otherwise get a soda straw or something firm but not sharp and poke it up into the drain. Water and crud should come pouring out. There may be a lot of it so stand back!
Don't be concerned about harming anything up inside the drain, you'd have to be trying, and using something hard and pointed to do that.

Thanks for the help! Sounds like something I can handle. I am not a mechanic by any stretch, but I younger then Now I tend to leave things to those who know more than me.

like luiq said
why the problem at low mileage,
also, never go thru the car wash with the blower on,, wax on the evap core is a life time of problems- it causes the core to hold water. mfg spend money on the core to make it shed water.

huh???...Waxes and oils are generally hydrophobic, which literally means 'scared of water' -- they don't mix with water easily.
If wax were hydrophilic, it would absorb the water! Yet when you wax a car, the water beads and runs off.

wax causes water to pool,,,i.e. wax your hood and spray it with water.
most mfg'er use a coating to prevent water to pool on the core,, if been there, ive worked for heat exchanger mfg. im well versed in your problem and its a challenge for people who dont understand the problem
if scared means its afraid to move then yes- its scared.

Perhaps you need to immerse a wax candle in a glass of water and see if it absorbs any water.
