AC Cleaning
So summer is coming up, started using AC. After having few cold days, i stopped using it and guess what it stinks. I searched this forum and found that its either drain hole plugged and mold on evaporator. Any one got a picture of the drain hole location. Also has anyone cleaned their evaporator yet with frigi clean or the Klima clean. In need of directions.

Found this:
Drain hose is the little pig tail that drops down from the evaporator core through the firewall to the rear of the engine compartment just aft of the front wheels.
Never needed to use the cleaner, but here are some instructions:
Klima
1. Turn off the car and make sure your HVAC system is completely off.
2. Spray the entire contents of the Klima-Cleaner into the center vent.
3. Wait 20 minutes.
4. Restart the car, open all the doors and run the AC for at least one minute with all the doors open, making sure that fresh air is coming into the interior.
BG Frigi-Clean
Drill a 1/4" hole and screw the fitting into your evaporator core housing and attach the hose, start your A/C and push on the top of the can to discharge the foam to coat your evaporator fins/core. It foams and rids the evaporator of mildew, nicotine, and dust. The residue runs out the AC condensation drain hole onto the ground.

^say what?
The only user serviceable part is the cabin filter...
OP open the cabin filter compartment up and change it and while you are in there, remove any crap with a small shop vac.
next go under your car passenger side and make sure that your hose coming out of the firewall is not clogged
finally remove any crap from the fresh air intakel and if you are feeling really industrious, remove it (the cowl and use a shop vac to clean it out.
