There really isn't such a wiring diagram such as you describe for the 91 -93 model. There where laminated wall charts for dealers that showed general layout of car and components of electrical system, etc.

Now the 94 wiring manual has grids in back of book that give layout of car but of course the systems are not exactly the same.

First picture 94-95 24v wiring grid but this grid is not in 12v wiring book so wall charts are where this info whould be available.

Second picture shows where cooling fan components are located but that is how 12v book is shown each system seperately after each system wiring diagram.

Thanks Steve,
the problem I am having is basically linking the different areas together, the areas I am having problems with at the moment are theoil level dipstick and the climate control airconditioning panel. With the electic dipstick we have checked it and it is ok, also we have checked the wire going to it, so the problem seems to be up at the back of the dash(with the manual I have it has the wires leading off the dash going to somewhere). As for the control panel we are having problems with the on of switch, not quite sure if this is the control panel itself or something else. Any ideas would be much appreciated.

No matter what I try, the climate control has a mind of its own. All I really want is the ability to run fresh air without the a/c or heater kicking in, but this car will have none of that.

Can you push ECON button and get compressor to disengage? I am assuming you have push button a/c control panel and not rotary knob type panel.

Does temp stepper motor move cable and lever in blower motor housing under hood to close off hot air from heater core when you go to LO setting?

Everything seems functional. Econ will work for a while but it will go to auto depending on temp setting. To clarify, econ light stays on, but system acts like auto. Or rather semi-auto. It also keeps my fan speed and air direction the same. Can't complain too much since at least when I need cold or hot I can get it, but still sometimes you just want fresh ambient air.

I might be wrong, but my recollection is that you can't get just vehicle speed driven ambient air through the system without the system acting in automatic (with fan and temp controls active), with a/c or without a/c. The econ setting just turns off the a/c but leaves the auto controls doing their thing. The auto setting (with light on) turns on the a/c above certain temperatures.

You could set the econ button, and turn the temp setting low. This will try to set the internal temperature of the car with just ambient air, but the fan will still seek a speed setting depending on the temperature you manually set. Play with the temp until the fan runs at it's lowest speed. The only other option is to hit the off button, which seems to cut off all incoming air and shuts the system down completely, and open a window, lol.

I had wondered about the same thing, and playing with the temp setting while on econ is how I do it. I rarely ever use the a/c anyway, except to defog windows in the rain.
