Dash Air Conditioning

[kspickard]

I have a 2004 Alpine Avalanche. I am not getting air flow from the front A/C vents. The blower is running along with a small vacuum pump mounted on the front firewall. The pump has a hose disconnected, but I cannot find any place to attach it.

Hopefully someone with this model can look behind the generator cover above the left headlamp and post a picture of this pump and its connections.

the vacuum hoses attach to the back of the rotary selection knob for Max AC, AC, etc. They don't attach very firmly, just slip on & barely fit, but w/the vacuum they stay put till they get bumped.

All I see are electrical connections. I took a photo , but not sure how to include in the reply.

Thanks Mike for the input. Vacuum hose was disconnected from the accumulator.

You may not have needed the heat yet, but also check the heater hose under the small sofa on the passenger side (main furnace), on my old Avalanche, the hose was pinched closed where it went thru the sofa! Also, the dash heat and AC hoses were crushed in a few spots, may want to double check those.
