I just put in a new heater core and now the vent/ac/max aconly pushes out the faintest amount of air. where do i need to look to fix this??

FivePointOhh

did you plug back in your vac line?

check the white one right behind your glove box

also check all connections there should be a tri wire connection that is your blower motor power. check that

exactly, +1...odds are you have a loose vacuum line somewhere

mckibben2890

all the vac lines are secure. when i turn the switch tovent it kind of farts, when i turn it to a/c i hear it click once, does this mean i have power? i can't find any loose or open connections...

FivePointOhh

pull the switch bezzle out and see if you pulled anything looose. also you might need to check some connections for continuity(sp?) you're losing power somewhere it sounds like.

but for some reason i'm suspect of the vac line still.....

don't know what it was, but i opened my glove box to pop the trunk, shut it, and the air kicked on magically! lol

better double check to see if no vaccum line is pinched...the vents are all vaccum operated and the blower speed is electrical
