| Post subject: | Evaporator Drain Clogged |
Alright, so as a follow up to my previous thread about repairing AC, I got it working. I vacuumed the system for about 2 hours, oiled it, and charged it, and it is working perfect, with the specified pressures in both the low and high side. The only problem I am having now is that my passenger side floor is soaked! So I assume the evaporator core drain must be clogged. Is there a "standard" way to fix this, or should I just get underneath with a wire hanger and try to unclog the drain coming out of the firewall. Thanks to all that helped me previously with this repair, it went great! |

I just pulled the cowl just in front of the windscreen on my 05 and the AC/heater air intake has a solid raised lip and is covered by about window screen size metal mesh so it's relatively unlikely that your HEVAC is full of trash. I mention this only because my 1993 Dodge lacked that feature and the heater core wound up packed with leaves. I don't know exactly where the drain is but it should be about midway up the firewall on the passenger side. The ones I've seen in the past are a right angle rubbery tube that's clipped to a metal or plastic extension thru the firewall from the HEVAC unit. Commonly that tube has what looks sort of like a crimped end that can become clogged or with age get to the point were the crimp is so stiff it won't open and let water drain. On at least one occasion I had to remove the tube and cut the very end of the crimp off. |

Its just a small tube on the low part of the firewall pass. side, a small amount of pressure should clear it. |
