Need help identifying vacuum line...

[NerdPower]

The line is broken and I want to know what it goes to. I also need suggestions for fixing it without having to replace the whole thing.

Thanks!

What motor is that? Year make and model of car?

That is the one that runs down left of the fuse box, right? I think it goes into the large wire conduit that goes back into the cabin. I think it's used for the HVAC. Do you're HVAC controls work?

Sorry! 1999 Grand Prix GT 3800. The line is in the back of the air intake manifold near the firewall. The brake boost vac line connects there as well. It runs across the back, over the passenger side strut then down between the fuse box and battery. Then it goes along the cable coming from the fuse box to the back.

Yes they work but air isn't blowing out the vents like it should. You can hear the blower so I think it's the bend door actuator. Anyway it's causing code p0171 to show up and the car seems to burn a lot gas so any ideas to properly fix it or can I just cap it off?

Find the other end of it in the conduit and hook it up. Your HVAC problems may go away.

P0171 lean condition. Yup, that makes sense.

Yes it is the vacuum line to the cabin vents and it will give you a lean condition if open just find where it is broken and put a new rubber hose on it also will give bad milage because it is allowing air in after the sensor. easy fix

It's a vacuum line that goes to a check valve and T down by the fuse box. Then it continues over to the fender for a black ball which is a vacuum canister.
