A/C HEATER PROBLEM
 

As another guys here, my heater only vents to windshield, either I push any button. I've been see that the problem probably is the vacuum lines, i check my vaccum power box behind right headlight, and there are 2 hoses connected, but is a third that is unplugged but there's no any place to connect it, some one can explain me how is the right connection in the vacuum power. Thanks

if yours is a non-turbo, you should have 3 hoses. one is mounted onto a switch there on the vacuum servo above the carbon canister filter. that one should go to your heater cock valve (located at the rear of your engine on pass side, where the hoses go in thru the firewall to the heater core. one of the other 2 goes thru the firewall to a T just on the passenger side near the tranny tunnel. the 3rd goes to the rear of the intake manifold.

If your car is a turbo, there are 4 nipples, 3 like above and the 4th goes to the vacuum pump inside the front of the passenger fender behind the headlight.
