My air conditioner overflow box may be plugged. Where is the drain hose end loca

The drain tube is located on the firewall (rear of the engine compartment) low on the passenger side. You'll probably have to raise the vehicle to reach/find it. DO NOT crawl under the vehicle unless it is supported by jack stands or ramps.once located(look very good,hard to find on some)using a flashlight and use a metal coat/clothes hanger,cut it,straighten it(bend a little on the end if needed),pushing in & out carefully/gently to unclog the crap in it.be prepared for water/crap to come rushing out once you get the junk out.once the water drains out,you can use compressed air to blow into it to help clear it 100%.
