Mysterious vacuum hose.

Gyratingyak · Sep 20, 2017

So I have a vacuum hose that I have no idea where it goes to. It comes off the vacuum T in the intake into a grommet near the AC hose inlets. There is room to put two more holes in the grommet which would help when I install my AF, oil and vacuum gauge. Because I really don't want to drill into my firewall if I can avoid it

Vacuum supply for heater actuator valves?

Yes, that is the vacuum supply for the AC/heater box under the dash.

I can't see where it connects under the dash. The AC/heater box is huge and blocks my view. Guess I'll have to go fishing to find out its exact location

If you'll activate the system, you'll realize what the prior posts are true when nothing happens.

Remove the glove box and you can see the top of the heater box and vacuum lines.

I guess I'll be doing a few things all at once. Wiper shaft seals and this along with my new glove box. Thank you!
