well i dont know for your year accord, but my 6th gen has some AC filters, when they are "done", they reduce the air flow..

They are located in the ac/vent/evap. assembly.

 

I don't think the '93 had cabin "fresh air" filters. Nothing in the service manual about any. Does anyone know for sure. I might add that switching between fresh air and recirc mode doesn't change anything, air flow still low. My Maxima on low blows out more air than this does on high.

 

It might be leaves and junk that have collected over the last 15 years. You can try taking out the evaporator and see if anything there needs to be cleaned out. It might be that the fan is dying, you could check that too.

 

The blower seems to sound like its working like it should. You can here it gradually increase in speed as you're turning the ****. I'll probably just rip the dash apart this weekend and see if there is some kind of blockage.

 

Tore the dash apart this weekend and found the problem. The whole side of the evaporator on the blower side was covered with no doubt years of dirt and dust and who knows what else. It's a wonder I was getting any airflow at all. Took a tooth brush and carefully cleaned it all off and blew backwards thru it with compressed air and vacuumed all that crap up, put dash all back together and she blows real good now.
