Default Need help! Where does this vacuum line go to?

Like title says, in the process of putting the 69 back together and do not recall what it goes to. Any help or picture's would be much appreciated.

Thanks

On my '72 roadster, that line goes over and above the heater box and connects to a "T" of a much larger vacuum line. Can't supply more info, as the car is currently under cover until the weather breaks a little more.

Hi l,
As Duane said that small vacuum hose is connected in a T in the vacuum supply hose for the wiper door actuator. It supplies the vacuum that operates the heater and defroster controls.
Look for a T with 2 large nipples and 1 small nipple.
Regards,
Alan

This is it's position on a 71.... just forward of the right side hood latch.
The yellow hose is the supply for the wiper door actuator and is on the way to the wiper door relay.

Hi I,
I looked at your photo again and noticed that the Wiper Door Limit Switch is mounted up-side down.
You'll need to flip it over in order for the linkage/plunger on the wiper door mechanism to be able to operate the switch.
Regards,
Alan
