I've never done it, but I think weed whacker line is the recommended "tool" for rotor rooting your drain lines.

That's where a suction hose comes in handy. The drain is on the far side behind the copper cap-tube. Snake a hose and use compressed air to agitate.

I've never had to do this, but If all else fails you could get under the car and snake up some weed-trimmer wire. Similar to how one might clear the sunroof drains.

I have done the weed eater line trick for the sunroof drains, but not the other. Just wondering if it was the same idea. Thanks for confirming. The thought of pulling the console and maybe dash for this is not something I want to do. I just got finished putting it all the interior back in!

The tube for this drain is directly under the X of the X-pipe, right? Can it be accessed with weed eater line with the X-pipe still installed?

Foamed 2x, let dry, put back together and it made a HUGE difference in airflow and cooling.

This makes me happy.

Smells better also.

Mine needs doing now 8>)

SeanR

Dork, yours is just fine. The mechanic you sent it too the other day took care of it.

Sean, how did you clean up after the foamy stuff did it's thing? Did you rinse or vacuum? If you rinsed do you think everything flowed out ok through the drain hose?

I've used the original liquid Coil Cleen stuff from Lundmark on my home AC unit... its nasty stuff to play with though [wear a respirator]. It worked reasonably well. I imagine the foam stuff works a lot better though.

SeanR

I foamed it and let it sit, then took a water bottle and sprayed a bit on it. Seems to have cleaned up but anything is better that when I had before.

Man, I've got a lot done today on mine. Kinda glad my top end refresh guy didn't get here early.

I'm thinking that the resistor pack can come out for better access to the coils on the driver's side. That will also keep it away from anything in the foamy stuff that might hurt the eletrical parts.

I have a small detail vacuum attachment for clrening vents and the like, a small tube with a mini dusting brush on the end. That will be the first weapon used, to get any loose stuff out. My drains are working OK now, witnessesd by the hissing and boiling noises I hear after engine shutdown with AC in service. So after the foam, I'll use a GENTLE spray on the evap unit, starting at the bottom and working my way across and then up. That way there will be enough water to carry the crud out through the drain without overwhelming it. That's my plan for now. Film at 11...

Pretty much ever one we see is like that, some have been worse.

Jadz928

Good plan, Dr Bob. Didn't find the resistor pack to be in the way, but the freeze switch rod comes out easy.

dr bob

I was thinking that I could do a more thorough job vacuuming and spraying/rinsing if I had additional access through that hole where the resistor sits.

Sean- The foam cleaner works great, I used it on the 85 and the AC is as cold as ice. Its in the plumbing dept where all ducting goods are.

I supported you today, bought two cans and a buttload of other stuff while I was there.
