Hi, my 95 Firehawk is a time capsule and now has 6200 miles on it. The steering wheel radio controls do not work. The buttons feel perfect and the plungers haven’t melted. They have no lights and do not control anything on the factory deck. I even replaced the radio with a NOS unit also from a ‘95 as the CD player wasn’t working. Some of the directions of the power mirrors also do not work. Perhaps the wiring harness connections have some corrosion and the harness behind the airbag needs to be replaced or the connections cleaned? I checked the fuses and did not find any that are burnt out. I mention corrosion only because there is some surface rust on the exhaust headers. The car is a TX car and maybe the humidity has affected these things as the car was used infrequently.

Thank you in advance for any help you folks can offer before I take the airbag out and replace the harness.
