Sometimes my digital speedometer works and then it stops working. I never know how fast I' am going and it is annoying. What can cause this problem and how can I fix it?

Hello,

This is the LCD screen which they had a problem with. When this happens you must remove the instrument cluster and send it to be rebuilt. AER does this, here is a video of the job being done on a similar car with diagrams below to show you on your car. Sometimes just unplugging the cluster and plugging it back in again can fix a bad connection.

Check out the diagrams (below). Please let us know what happens.

Cheers, Ken
