We acquired a 2004 Toyota 4 Runner for Ava to drive until she's ready to handle the Acura. I'm in love with the damn thing. I plan to claim it as my own ASAP. I mean you can tell it's old but it's just so damned manly.
But being old it comes with old truck problems. I've already DIYd a wheel bearing on the thing. Yesterday revealed a new problem and one I should have picked up on earlier.
Since we got it, the AC has run great but has made some funny noises when turning. Fan would sound like it was struggling. Had a scent too like the interior has been wet in the past. I took it out yesterday and when I got home I saw water coming from the left rear corner of the frame. There was water getting into the interior and the carpet was soaked. Where it was coming from clicked immediately when I put 2 and 2 together and realized that the funny noises and the fact that I'd never seen condensate under it told me it was coming from the evaporator box. The evaporator drain had to be clogged.
So I found the evap drain on the engine side of the firewall here. A small 45 degree black hose just below center on the pic
Fired the engine up with the AC at full blast and started reaming that hose out with a length of weed eater wire. As soon as I found the clog the thing poured a crap ton of water.
Spent the morning with a shop vac cleaning the carpet. Unfortunately it's looking like replacing the carpet is in the offing. Actually looks fairly straightforward and cheap. I'll document it here.
