The evap drain is clogged - very difficult to access from the engine bay, no way to really even remove the hose. I'm sure the evap area in the dash is full of pine straw and whatever else. I can't figure out any way to access this... On most vehicles you can remove the blower fan, but on the mpv the fan is nowhere near that evaporator coil.

Any thoughts? I've got the drain flowing now after shop vac'ing the tube, but I'm positive that the housing is full is debris

 

Update - I was able to remove the ductwork between the blower fan and evap coil on the passenger side. This gave access to the evap box which has a bunch of deteriorated foam in it. I assume this is what's blocking the drain. I see of zero ways to access the drivers side. I used some evap coil cleaner (includes a long tube) to blast through the drain hose. I suspect this is going to have to be done a couple times a year since the foam is still loose on the drivers side of the evap box. Worst case I can cut an "access hole" in the drivers side of the box and seal with aluminum duct tape.

 

Hi, I want to clean up my evaporator on my Mazda MPV/8, perhaps you can share a picture to the ductwork location that you referring to? Thank You

 

Hello jeyzou. I ended up selling the mpv, and I can't remember how I ended up accessing the drivers side. I vaguely recall that I was in fact able to access it - I don't know if I cut an access hole or what. But I specifically remember the passenger side of that coil was absolutely caked with debris.

 

Thanks for the info, I'll have a look around the driver side then ya.
