94 wiring diagram for heat/ac controls

[smith5170]

I am looking for the wiring diagram(s) for a 94. The control for the heat/ac will not change the place that the air comes out of. It is stuck on def./floor. I have looked in the Haynes book and it has everything except for what I need. I replaced the temperature control panel and checked for vacuum. PLEASE HELP!

i think that is a vacuum problem.

have you checked the electronic/vacuum Box (you see an picture in the Haynes Repair Maual on Site 3-13 illustration 11.8) i had the same problem, by the box was an hose away from the Box.

you can also test the vacuum when you pull a hose of and the engine runs you must hold a Finger of the open vacuum connector and you must feel the vacuum.

2. you have an vacuum-valve that regulate the rear heater. perhabs there is an acuum Leaking.

i hope that helps you!
