Does anyone know where the A/C drain line is on a F150? I noticed some condensation leaking inside the truck below the glove box a couple of days ago.

I assume the drain line must be clogged. Any help would be appreciated. thanks

 

what year is your truck.

 

I'm sorry, it is a 1998 f-150 supercab.

 

It's on the lower right side of the firewall, a small 1/2" tube protruding out. It may or may not have a hose/nipple on it. There was a TSB on your year for oxygen sensor failure due to moisture dripping on the sensor from the A/C drain. The TSB fix was to reroute the drain away from the sensor. If yours had this done, you might check & see if this is plugged.
