Q: A/C button lights flash on/off randomly

asked by on

Just last year, I had the A/C unit replaced (my car doesn’t have climate control). This week, the A/C button lights came on and they flashed on/off while I was driving. Sometimes they will stay on and then I have to press the button to restart the unit. Then the scenario starts all over. Other times it will run for up to 40 minutes before the problem starts again. What will solve this?
