I can't speak to your specific model, but I have used a water pic to clear
the drain. Ram the hose up the drain outlet from underneath and let it
rip. You can make a pretty good mess in the process, but the spray from
that little dental pump is strong enough to break up the accumulated crud
and wash it out the drain. I use the same method when I start to get a
sour smell out of the unit - just add a couple of teaspoons of bleach to
the water

Use the coat hanger to dig around inside the tube that protrudes
through the firewall. Then hit it with a shop vac. And don't dig
around too far bacause the evaporator is only a few inches away. 2-3
inches is as far as it needs to go.

You're making a big mistake if you drill a hole in anything on that
model.

Worse case, it really isn't that hard to pull the whole HVAC unit
out. If you haven't done the blend doors yet then you'll have it
apart eventually anyways.
