Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, the most common issue with the TBC fault is a failed module. A diagnostic check for codes with a scan tool that can check the TBC system needs to be used to verify this. As for the radio, that could be an issue with the fuse that controls it or an internal fault in the radio. Start by checking all fuses in both the underhood and interior fuse panel for these systems. The AC system is another question. How do you know it has enough freon in the system if the compressor doesnt engage? Do you have power and ground to the compressor clutch?
Do you need more help with this concern?
