When my ignition is on but engine off all my lights work but when i turn the engine on the only lights that stay on on the cluster are my climate and the one all the way to the left??? also when i turn the engine on those lights get reali bright then die?? thanks for any help

 

Please let me know if you find out the root cause of this problem, I have a very similar problem...When the lights are off, I get the radio lights on, when I turn the lights on, the radio lights shuts down,the rest of the lights in the car will work butI've seen them going from very bright to very dim to the point of losing them totally?

 

what years and options?
