Q: Radio and AC buttons don't work

Hi, thanks for writing in. I would recommend having all of your fuses checked first. It is unlikely that both of those control units would go bad at once. Here at YourMechanic, we can have a technician come to your home or office to inspect your electrical system for you, and make or suggest the necessary repairs. We can also get the rest of the radio and climate control system checked out. If it turns out to be a fuse, fuses are relatively inexpensive and we can have the problem fixed in a short time period. If the fuse is not the issue, you may have an issue with the wires behind these two systems. The wires could be exposed somewhere and cause a short between the two systems therefore hindering their operation.
