    Taking off heater blower off on 1994 GMC Sierra 1500

    I took the glove box out and located where the heater blower is. What is the easiest way to get that plastic casing off?


    Thanks

    You have to take ecm/ computer out .. take bracket loose from side of dash .. so you can move the dash up just enough.

    Have fun, have had to do this was a big PIA, IIRC when I did mine, its all under the dash, had to remove couple screws for dash move a bracket out and pry up on the dash to fandagle the fan blower motor out.

    just got a 2005 jimmy , When I turn the fan to the off position and wait, then turn it on, I get a small blast of warmth, but then turns cold again. (need heat) -25 here

    Might try resetting the hvac/heater system click here..look in the radiator see if you have the pink coolant dexcool..if so flush system..put green antifreeze back.
    Does the air get warm if you drive it? Weird symptom though..i will search see if anyone else had this problem .

    Gitter done have fun. Running on empty...running blind...running behind.....
