The DIC display on my 06 does not come on all the time. Sometimes it does and sometimes not. Any help would be great.

 

Is it just too dim to see? The dash lights dim automatically according to what the ambient light sensor senses.

 

Did you check your fuses?

 

Where are the fuses for the DIC located? Under the hood, or in the console?

 

There is some info in this thread about the DIC fuses. Mine straightened out by itself and has been o.k. for the last year.

Am I the only one who thought of recommending Cialis for your DIC?

Everyone here is just so mature and helpful...

Actually, OP, I hope the fuse is the culprit, or your dimmer is turned way down or something simple.
