Hi guys, i have a 2011 f150 that has a musty smell coming from the air vents. ive read lots of threads and am trying to locate the a/c drain in passenger firewall. Does anyone have a picture of exactly where it is / or looks like? i see a plastic fitting sticking out at a 90 degree angle thru the firewall. it looks like it has a silver/ metal piece on it of some sort. might that be it? i stuck a coat hanger in there about 7 inches but i never felt anything at all. Thanks in advance

 

the musty smell from the vents is mold in the evaporator from not drying it out before parking the vehicle. ( about a mile from destination turn the ac off but leave the vent on. turn the fan speed up to dry it faster. ) if that doesn't work then it would need a hole drilled in the evaporator and sprayed down with lysol. hopefully you don't have to do that. good luck
