I have a 97 STS and just had my steering wheel controls (volumn, cd changer controls, air temp control...) stop working. This buttons on the dash for these same steering wheel controls do work; its only the steering wheel controls that are not. I believe I checked all fuses related to this area; cluster fuse in the trunk compartment, all are fine. My next step will be to inspect the entire steering wheel column for possible fuses or disconnected wires... Has anybody had this problem? I'll greatly appreciate the help.
