Does the fan work on #4 setting only?

Yep. Certainly sounding like the resistor at this point.

That's what I'm thinking too.

To the OP - the backlight being burnt out is likely unrelated.

There is an excellent how-to here on how to remove center know, remove bulb with vacuum home, what bulb # to get, and how to reinstall.

Yeah to fix that you need to pull the knob off and the bulb is recessed inside, forget what size.

Its this bulb:



Sylvania 2721.

I have discovered the same bulb is used to illuminate the power socket in the ash tray. Ask the dealer about a replacement and they tell you that only the entire socket assembly is available for $55. But you can disassemble that too and replace just the bulb.

let me try and see if the #4 works, i tried it up til #3 what are the chances that it could be the blower? hope not,, I'd hate to pull it out,,, before I try to pull it out I'd need to continue doing more test on the rest of the stuff, ,,,,,, when button is pushed for the recric, light works, but the A/C does not,,, any more suggestions?

Check position #4, it bypasses the resistor pack and applies 12 volts to the motor. If it works there then the resistor pack is bad, my sons car, the pack was rusted because the PO didn't put the cabin filter cover on The correct way
and water trickled down to the resistor pack and kept it submerged.

position#4 still does not turn the blower or heather on,, so now the question that I have,, is fuse #25 (25Amp) the only fuse for the blower or is there another one that I'd need to check?

Pull the glove box out and drop a 12v battery straight on the blower motor. If it runs, then chase wires.

I"m chasing the wires now, it's not the motor, its not the fuse, and I have no current going through the resistors and the motor, so I am thinking the culprit may be the blower switch,.


As far as I know,
there is only 4 different things that could malfunction, fuse, switch, blower, and resistors??? Am I right on this???

Fuse, fan blower, resistors, fan switch, are not the culprit, does anyone know which relay provides current to the fuse box?

..........bet it's the Fan Switch!

Those circuits are fed thru the 75X (that circuit is disabled during the START MODE of the Iginition). In the On position (Iginition) the Fan and other accessories will function.

The Fan Switch (E9) circuit is fed by fuse #25 (which happens to be a 25amp fuse) and does not involve a relay. The Switch can be bad and it "will not" operate the fan on #4 position.

With Ignition ON, the Fan Switch must be ON before the Fresh Air function or AC function will operate whether their bulbs are blown or not.

There is a How To as well as a current Thread of discussion over in 101, which includes a few pictures of the switch and what happens internally when it goes kaput.

Hope this helps!
