Re: How do troubleshoot a blockage?
 

Thanks for the responses so far.

It is a 1995 Accord EX, standard, 99k, 4 cyl, here in New Hampshire, US.
Sorry.

Reason for suspecting blockage is based on suggestions by auto shops in
the area. If I turn the fan on, I can hear it come on and accelerate at
higher settings (off through 4). So the fan seems to be blowing.
Additionally, when I go from recirc to fresh air and back, I can hear
the difference there as well (recirc being louder).

We are not getting any real airflow through ANY vents - lower, torso, or
defrost.

We also suspect an A/C problem, but that may simply need a recharge or
something similiar. But without a good airflow to feel, I'm not really
looking to address that issue yet. First things first, I guess - UNLESS
someone tells me that the two issues are likely related. Then, of
course, I'm all ears.

Will look into all suggestions and see if I can figure out how the air
flows.

Thanks again. Worked fine. Unfortunately I found a TON of stuff in there
- both in the area of the blower, and in the base of the evaporator -
which I pried open to see inside. Looks like whatever creature bedded
down was quite comfy. They were also nice enough to leave plenty of
droppings.

Good news is, the blockage is gone. Bad news is that the air smells
horrible. Guess I'm looking to replace the evaporator at a minimum and
hope that clears the air.

Thanks for the feedback.

I doubt the evaporator will have to be replaced, but the housing will have
to be cleaned thoroughly. Depending on where you live this could be a true
emergency. Here in the desert southwest Haanta virus is endemic among
rodents. Haanta is by airborne particles from rodent droppings, and
the effects are horrendous. Beyond the high mortality rate, recovery is slow
and nerve damage is common. 10% bleach solution is the sanitation of choice;
alcohol is ineffective against the virus.
