Does anyone know where the drain is for the A/C. From what I have read on other sites they can be very tricky to set up so that water does not leak on to the passenger side floor board. From what little water mine drips it lands in two different places under the truck. It must be running along side a frame member or something. I have looked under the truck and cannot see any kind of tube coming out from the firewall what I would expect to see since the evaporator is located in the passenger compartment

 

I noticed this question posted. I'm also a little perplexed about the AC evap drain. Mine also drains somewhere along the frame but cannot pinpoint location. I also notice that it will spit water on the ground when one of the doors is closed. Just thought it odd. Anyone know??

 

There’s a drain on the passenger side firewall right in front of the evaporator. You should be able to see it from underneath.
