2002 9-3 SE 5 Dr ACC

The Blower in my wife's car just quit. No warning, funny noises, intermittent problems, it just quit. No Hi speed, No Lo speed, no nothing. Nada.

All fuses, even the ones under the hood are good. The relays all check out OK.I removed the cabin filter and spun the fan. It spins freely. (Note to self: Replace that filter every couple of years or so. YUCK!!!). Just in back of the fan (towards Driver Side) there are 2 relatively thick wires, one red and one brown going into a connector which I assume to be the Resistor. I measured for voltage, they both had some, the Red one something over 14 V, the Brown one about .2V less.

Where to Go? What to Do? What to Check? All suggestions gratefully accepted!

It looks like if I need the ACC Resistor I may be SOL as both FCP (Good Guys) and other online specialists only have the MCC Resistors.

If I in fact do need the Resistor, and if it is not available, I'd be very happy to do some jury rigging where I would only have one or two speeds plus OFF. I would need someone to tell me how to do it though.

Cold weather is coming, the Defroster is an absolute necessity

That connector is not a resistor on ACC models (it's where the MCC resistor is located tho), it is just a crappy connector that allows Saab to use the same black connector on the wiring harness side of the cirucit on both models. It's a common problem on ACC cars that it melts and then the connector blades corrode and the fan stops working, just cut both sides of the connector off and connect the red and brown wire directly to the orange and brown wires on fan motor (red to orange, brown to brown).

If you have voltage at the wiring harness side of the connector I suspect that is your problem, but also could be the fan speed controller (ACC equivalent of the resistor, located behind the black hump on the inner forward portion of the passenger foot well). Or the fan could be dead, but connecting +12V directly to the orange wire of the fan motor and ground to the brown should quickly tell you if the fan motor is good.

Halfway there?

Thanks Jake, I appreciate the suggestions.

I supplied 12V from an external source and the fan operated properly. I bypassed the connector by wiring the brn-brn and red-orng. The fan does not work when wired like that. I applied the external source again (Still leaving the Brown and Red Wires connected to the fan) and the fan works great. Engine on, engine off, it doesn't matter, as long as I have the external source (jump box) connected the fan runs great.

I know nothing about electronics, but measured the voltage at each of the wires with the engine running, they were exactly the same at about 14.1 V.

What should I do now? Your help is most sincerely appreciated!

ACC Speed Controller

Thanks, just a visual inspection or are there electrical tests?

Can I just bypass the whole thing and have a single speed fan?
