Acura Repair Questions? Ask a Mechanic for Answers ASAP
Hello, I will try to assist you the best I can. electrical issues are by far the hardest to diagnose especially over the computer. Please be patient and ask as many questions as you like.
Did you check the fuses yourself or are you going on the word of the dealer?
What was exactly done to repair the a/c system?
I need as much information as you can provide.
are you equipped if need to remove the radio to check for power and grounds?
yes the next logical step would be to check for power and grounds to the audio unit. If they are good then I suspect the audio unit is bad
if power and grounds are good to the audio unit, it could be the knob or the unit could be at fault. a aftermarket will fit but with some modifications and harness adapters. You can try www.crutchfield.com they have representatives that you can talk to you that can walk you through the whole process.
