Its seems to me that less air (just fan or AC) is blown in my accord compared to one of my friend's with same model. Also, If the position is set to "inside air" then more air flows and with "outside air" less air flows. I read about cabin filter but some say there is no cabin filter in 93 accord EX !!

Can you suggest anything? What should I try?

 

you should notice a difference in recirculate and fresh settings, but as far as an overall flow comparison, your blower may be a little weaker than your buddy's, or your evaporator may be covered with dust,leaves, etc. blocking air flow. You can remove your blower motor, reach your hand inside the case to see if you feel any buildup of debris, then vacuum it out.

sgraham01, how to remove blower motor ? Is it difficult? Is there really cabin air filter in my car?
silent1jt, I don't have any odor etc.

Thanks for your help.

 

blower removal is super easy. get under the glove box and disconnect the 2-pin connector on it and remove the 3? screws holding it to the air box. there may also be a cooling vent tube that will need to be pulled loose. This would be a tube that backfeeds incoming air to the motor so it doesn't overheat. you will probably need to take the floor mat out and pull the carpet back slightly to work the blower out. I'm not sure how tight a fit the 93 is, but on my 94, its tricky to work the unit out of the box, but it will come out. this would be a good time to buy a new motor if you decide you need one since it's already out. you can also unplug your buddy's motor and check the resistance through the motor leads with an ohmeter, then check yours. if yours has the higher resistance, it is the weaker one. the 93's don't have a cabin filter, but if you did, that would most likely be the problem. they get clogged and restrict flow.
