    Is it just my K5 or is it K5's in general, but, is there a solution for a weak A/C blower motor (yes...I have replaced it....twice). It seems to need alot of help but I have not come up with a solution.

    I've got one that I acquired from a Suburban that seems to put out twice the airflow than my factory one did. I remember that someone used to sell "super efficient" squirrel cages, but haven't seen one for years.

    I'm so poor I can't even pay attention [​IMG]

    Newer motors do put out more IMO... also newer resisters(sp?) help as well... first I would make sure all the tubes are clear of objects and that all the tubes are hooked up. It is very common for the heater ports to suck stuff in or become clogged and also common for the upper vents to be messed up and not attached right when someone pulls the dash cover.

    I went and replaced my blower moter and i asked for a burb blower, they were the same thing as my blaz moter i was wondering if maybe the fan might have blades that came in different angels to push more air.
    where would i find, "newer resistors", to replace them?
    how many tubes should you have to check for blockage and where are they?
    i've been in a 87 burb and i was shocked how much more it pumped out when compared tomy blaze.
    i've gone through all the equipment under the dash and made sure everything was connected correctly and placed material around all connections points to keep the air flowing through the system.
    i've been working on this issue for a long time and any help would be apreciated.
