The car has been siting for a few weeks now since doing the suspension. I drove it to the alignment shop this morning and on the way there something has happened to the climate control.

Regardless of the settings super hot air is blowing out of the vents except for the center vent. It still seems to work and blow cold air with the AC on. But also when I switch through the settings for floor, or windshield vents the vents in the dash facing the seats are still blowing.

Think I have a vacuum leak. where is a good place to start on this. The vacuum leak would explain the vents not redirecting but how about the super hot air? Thing there could be an issue in the duo valves?

Alright fixed the hot air issue.. But how about the vents redirecting under throttle load? Is there a certain hose that is always the culprit anything a guy can check with out tearing the whole dash pad/console off?

I believe there is a grey (?) plastic pipe running along the bulkhead at the rear of the engine which could be a culprit. Vacuum pipe but I'm not 100% sure though, so I hope someone in the know chimes in soon....

Thanks buddy. I'll check that out.
