    A/C Blower blowing out very weak

    The blower in my 85 CV is very disappointing

    Lately it has been anywhere from 100 to 110 in my area and I have been wanting to use my a/c but it doesn't blow strongly at all. The air is cold, but only comes out a little. It feels like there may be a blockage in the ducts but it blows like this on every setting (vents,floor, and defrost).

    I have taken the dash apart and felt inside the ducts but didn't notice any blockages

    Is it possible that the blower motor could just be getting weak? It is also very loud.

    I replaced the motor resistor and had it working without a resistor and it was still wimpy.

    Any help would be much appreciated as rolling the windows down is just not getting the job done anymore.

    I don't have ATC

    Thanks

    I would pull out the blower to make sure it is working properly and see if anything is hanging up in there. That is the only part of the system where a fan noise can come from.

    Just 4 screws to remove. Run it while its out just to make sure it's spinning well.

    Hope that helps, Larry

      definitely pull the blower and clean inside the case. its often packed up with crap. If thats all good, does it blow from everywhere at once? If so, you've probably got a broken air door inside the plenum, or maybe if the heater core has been replaced, the plenum isn't tightly sealed to the eucts. if you open the glovebox and feel lots of air blowing around back there, look at the seal to make sure its there, and actually making contact. When I did my heater core at one point, I didn't have the upper bolt tight and there was a gap between the plenum and the ductwork and most of the air was just blowing around behind the glovebox. The instrument panel did a really neat job of frosting up because it was cold while the rest of the car was hot as hell.

        when you pull the blower... look at the fins on the evap core. remove the hair/dirt/crap/etc. Enjoy.
