A/C drainage

[76f0rdcust0m]

Just bought 76 short bed f100, it has factory A/C but when you use it the unit leaks back in tho the cab on the the passenger side of the door jam. The guy I got it from said dust dobbers stopped up the drainage tube that comes off the A/C unit. He said he cleared out the dirt in the tube but there was still some up in there he couldn't get to. I don't know the exact location of this tube. He said it was on the passenger side beside the wheel well. I want to find it so I can get it taken care of because I want it running right. If anybody knows where it is please let me know! Thanks guys!

on the bottom of the a/c evaperator is going to be a tube that works its way down through the floor or firewall that drains the a/c condensate to the ground. just look underneath and find where it is. its going to be the only tube going from the bottom or bottom back of the evap box.
