Sounds like a PCI Bus issue. possible wiring problem somewhere.

What about the digital odometer display at the bottom of the Speedometer? Does it show the mileage or is it blank?

Do your headlights and parking lights work properly?

What about the back lighting for the Instrument cluster, Radio, Courtesy lights? Can you dim them with the headlight switch?

Anything else besides the Instrument Cluster and HVAC not working?

Possible Junction block issue.

Replace the Instrument cluster?

Do you have one that looks like this?



You can use later year clusters that look like this:

KM instead of miles obviously. You can also use an instrument cluster from a 300m. Need to stick to a cluster up to 2000.

Do you have ABS?

From the list above it doesn't sound like the BCM.

Some functions work..some don't.

Have you tried hooking up a scan tool to the OBD port under the dash? Any codes?

I suggest you take a good look at the C1 connector on the BCM. It's the Gray one. Everything you listed that doesn't work goes through that connector.

The PCM, TCM and ABS connect to the BCM through the C3 connector and those appear to work. Otherwise you wouldn't be able to drive the car.

What year/Car did the replacement BCM come from?

I suggest something in the wiring related to the C1 connector for the BCM. I can't help you any further. Maybe someone else has an idea.

It's possible the wiring for one of the modules connected to the C1 connector is causing a problem with the PCI Bus bus and bringing it all down. Maybe disconnect those modules one at a time and see if the rest comes up?

And take a close look at the OBD connector. There have been instances where the shell had broken and some pins shorted out. Did someone try to connect to the OBD and this all started happening?

Glad to hear you got it figured out and fixed. I know we weren't much help, but some types of problems are just hard to diagnose remotely or without special equipment.
