My 94 civic ex sedan is great and runs like a champ but having issues with the a/c blowing. The a/c blows nice and cold but barely blows out. I close the vent on the passenger side and the vent on the top of the dash and it helps out and increases the pressure on the 3 vents that are open but barely. Is there something I can clean out or possibly change out the fan maybe? The car has almost 200k miles any good info would be great. I know its an old car and isnt gonna blow like a new car, its cold enough just need more fan power

 

Do the mode control motor and recirc work?



Is the blower motor fan cup filled with leaves?

 

The resistor on the blower motor might be bad.

 

not sure, how would i check or clean it out?

As for the resistor on the blower motor be bad how would I test that? like I said the a/c blows cold and everything works just not enough pressure behind it

 

Remove blower, check for debris in cup.

Listen or watch for whether the mode control motor runs when you change modes.

When you push the recirc button, does the amount of air from vents increase?

Do all 4 fan speeds work?

 

Change out the cabin air filter (wink..wink.. let him look))

 

94 civics don't have that option for a cabin filter. That has to be retrofit by using a CRV evaporator box or a 99/00 civic box.

 

Yes.. that;s what the wink, wink is about. It's like going into most hospital's ER's and being told to look for room 13.. you won't find it.
