AIR CONDITIONING AND HEAT

2003 BMW 540i • V8 2WD Automatic •

Car is '03 bmw 540. Recently tried to rectfy a problem of no blower, a/c or heat by replacing the FSR and when this didn't solve the problem, I replaced the entire control panel. Again, no success. All I get on the control panel are the back lights on the switches. When I replaced the panel. Same thing, back lighting only, nothing else. Checked the fuses, they seem ok. Any suggestions.

The wiring harness could be the culprit, seen it happen several times at the dealer.
