I only know of the one, and I was never able to get anything through it to the point where I thought it was effective. I guess when I remove the transmission to replace the clutch, I'm going to town on that SOB.

Yeah, if you go through the top, you go through the fresh air vent with the blower removed. It's a long way to get to the evaporator though. It's much shorter if you go from under the dash with the blower removed.

I tried two methods. I went under the dash and through the hole where the blower motor resides. I also sprayed the cleaner up the drain hose.

Sadly neither method did squat. I tried my AC for the first time today in 5 months and it smells as bad as it ever did.
