Where is the AC condensate drain tube located?


Asked by Apr 12, 2015 at 11:48 AM about the 2010 Ford F-150

Question type: Maintenance & Repair

Foul odor when running AC. Think
the drain tube is plugged. I bought a
product to flush the system with but
can't find the drain tube/hole.

They are usually under the passenger side of the vehicle. If the drain was plugged, you should have wet floor boards on the passenger side. Look by the firewall, right side of engine.

Found it. Thanks. I stuck a wire up it but couldn't tell if it was plugged. No debris came out but the foaming cleaner did drain through the hole like it's supposed to. Seems OK now. Smells better.

My drain is on the pass side of firewall in the engine compartment. Have used air and also wire. Still fills up with very little drainage except on pass Casper and it fills up the hollow in the rocker panel under the door sill? Does your treatment have a brand name and where is it available? Truck is a 2013 supercab Lariat and pristine other than the plugged ac. Thanks AZ
