Outside temperature reading
 

I have an '09 Chevy Silvreado Duramax, loaded. It has a climate control system, and an outside temperature thermometer that hasn't worked since the truck came off the lot. Now, this isn't a big deal, but it's annoying to have the thing tell me it's 28 degrees out all day when I know it's around forty. The other thing is that the climate control system isn't working right because it can't sense the temperature in the "cabin". Anyone have any experience with this?

Bring it to the dealership...

I have had it at the dealer three times, and so far it hasn't been resolved. That's why I posted here.

warrenty it till it works

sounds like you need a new dealer then. a brand new 09 truck should have 0 problems. and a reputable dealership should be more than willing to help

they should be able to fix it. its there job to do that.

Take advantage of the warranty while its there.
