Having a clicking noise in your dashboard when your car is off can be pretty annoying. It may sound like a relay or servo motor that is going bad, but it can also be a problem with your HVAC system. It could be something as simple as the HVAC needing calibration, or it could be as complicated as a blend door actuator that needs replacement. Either way, this article will cover 3 common solutions to this issue so you can get back to enjoying your Chevy Impala again in no time!
What is causing my 2009 chevy impala to make a clicking noise when the car is turned off?
Clicking noise in my dash when car is off. It started doing this about a week ago, sometimes it lasts for a minute and then goes away and other times it will be there all day long. It is a very loud clicking sound that is coming from the center of the dash right under the radio.
The clicking sound is probably due to a problem with your HVAC system. It might be the blower motor, a blend door actuator, or it could even be that the ducts are just loose and rattling around. The first thing you should try is to turn off your HVAC and see if the sound stops. If it does then you likely have a blower motor or a blend door actuator problem.
