Having problems with your 2004 Chevrolet TrailBlazer ?
AIR CONDITIONER WILL ONLY BLOW THROUGH THE DEFROST AND FEET VENT. WILL NOT BLOW THROUGH THE FRONT VENTS.
I have a Chevy Uplander and inside the glove compartment is a panel that contains the "cabin filters" (2 of them). I'm not sure if all chevy's have these or not, but they are not listed in the owners manual. When we removed them, we couldn't believe all of the dirt, debris, hair etc. that we found. We were able to purchase new one's for $14.99 from Autozone, and now the air works just as good as when we purchased the van in 2005. you may want to check where your cabin filters are.
You vacumn pipes are perished ,work from the inlet masnifold backwards and iam sure you find a split or perished pipe
