AC air bounces floor to defrost

[sljkansas]

My Daughter told me the other day that our 03 Sport Trak, that the AC bounces from defrost to floor. I had a feeling it may be a vacuum problem, I'll ask here if it only does it up hill or under her heavy foot. Any hints on where to start first.

Check out this hose, its very common for it to develop a hole on the bottom. It is on the passenger side toward the front of the engine.

Thanks, is it the larger one with the arrow pointing to it, or the top one that looks like a vaccuum hose? I have to get the car away from her long enough to check it out.

It's probably a cracked vacuum line.

You know its been so long since I changed mine I dont really remember but I think its the bottom one.

Thanks again, I'll let you know what I find.
