never had it happen befre today. my mom used the truck for maybe 4 hours while i was in class, and when i get in and turn on the A/C, it smells musty and moldy. it didnt smell yesterday, and i'm horrifically confused. any ideas?
The airbox drain is plugged and did not allow the condensation from the cooled air to flow out and is causing mold.
Ever notice the water puddle that develops under cars and trucks that idle in the summer with the A/C on ?
Look for a drain tube coming out of the airbox under the hood on the passenger side.Run a piece of wire up through it to clear it out .
