Default wiring diagram for a/c 1994

Does anyone know where I can find the wiring diagram for the A/C of a 1994? I have theHanes book and it gives diagrams up to a 1991 but the book is supposed to be up to 1998. I can't seem to find it anywhere on the web either. If anyone could help me out, it would be much appreciated. Thanks.

There is no separate A/C wiring diagram for your van since all A/C wiring ties into the PCM. The wiring can be found on the engine compartment wiring diagram.

Is there some specific problem you're looking for the answer to?

I need that kind of diagram for my year, 1994. I have a feeling from research and process of elimanation thatmy problem is the clutch cyclingswitch. But it doesn't look like that in my van, hince why I need the diagram. Compressor is working and still blowing cold air to the back system, front system is blowing warm.Still has correct pressure as well. Just got a `manafold gauge and was hoping that would help me diaganose my problem, but the fittings won't hook on to my system correctly, my system and the manafold gauge are R134 so I am not sure why it won't work.[sm=icon_flaming.gif]I am about to drive it up for a free estiment I have about reached the end of my rope. But any more input or a diagram is appreciated. Thanks for trying to help.

Your gauge hoses don't fit because your A/C was probably R-12 that was converted to R-134a and whoever did it did not install the R-134a fitting adapters.
For the diagram take a look at pins 27 & 34 on "Figure 5" to see what I meant about the A/C tying directly into the PCM (Powertrain Control Module.)

If the rear A/C is blowing cold but the front is not, the problem has nothing to do with the compressor, R-134a charge, or the cycling switch. The problem is limited to the front duct assembly. It maybe something as simple as your air blending flapper door being stuck over to the heating coreside and not allowing air to come through the cooling core. It could also be a bad heat-A/C-vent-defrost control switch that's not switching it over.
