Vacuum line to control vent for outside & recirculate

[littleblueGT]

I have spent all day looking for the vacuum line that supplies vacuum to the vent control with no luck. I removed the center console to check the heater air conditioning control module, and the valve is working. I have checked all the vacuum lines I could find, but couldn't find one that went into the cabin. The car runs fine and the brakes work good, so it can't be major. Does anyone have an idea of where the vacuum supply line is and where it enters the cabin?This is turning into a real pain in the ass!

check by your power brake booster. it should be the line that has the check valve on it.

The brake booster was the first area I looked at, but I couldn't see any line running into the cabin, and found no leaks. I also removed the heat shielding around the vacuum lines to check for leaks. I ran the car up on rhino ramps and crawled under to try and find a vacuum line going into the cabin- no luck!I have an 03 GT.As I stated before I also checked the climate control module, and the vac assist to the gate that controls inside/outside. One simple vacuum line, and I can't find it!

I finally got it! Had someone said the vacuum line enters the cabin above the heater lines on the firewall it would have really helped. I guess when the dealer was working on my car they must have pulled the vacuum line out of the firewall. At least I can now control the vent.

sorry, guess i should have said, thats the line, just follow it. you live you learn.....god i hate that song.

Cartman, the line you referenced was just hanging there and did not go any where. I thought it was a vacuum bleed line. That was the main problem I was having as I couldn't find a vacuum line entering the cabin, and I couldn't find a hole with a grommet that a line would fit through. Thanks for the reply.
