1994 Corsica heater Problem

[esrman]

Can somebody tell me EXACTLY where the vacuum line from the heater control goes on the engine?

I have vacuum to the switch BUT it seems really a low value.I think there`s a line leak somewhere.

And does anyone know what the vacumm reading should be at the switch,and can you check that with a regular car vacuum guage?

if not,will Auto zone check it for me?

My email addy is...

Ok, I mfound the problem.There was a leak in the vacuum line going to the cruise control,which te heater switch takes vacuum from off a littel double fiitng just before it goes to the cruise control.

Auto Zone ha a small-enough vacuum line that`ll fit those small plastic lines the factory put in.
