Does anyone know the location of the evaporator draining pan. I was getting a lot of water on the passenger side floor board. I think I have cleared out the drain on the firewall side and now do get a good drip coming out onto the driveway after running the air conditioner. Ran a wire up the drain tube (which did not work really well for me) and then shot up compressed air (gas station) which helped condensation come out the tube. But still get some condensation coming down from evaportor area inside the cab. I am assuming that there is still a water accumulation in the drain pan where ever that is. I had seen a mention that a very shallow 1/4" hole can be drilled inside to get rid of this water accumulation, but can't find where this drain pan area connects from the inside of the cab to the engine side fire wall. Or maybe drain tube is not fully connected under dash but can't find that connection either. Hoping not to have to remove the entire evaporator assembly which would require evacuating air conditioner lines.
