on my newly acquired '03 trailblazer i noticed that the steering wheel controls have the DIC control buttons but the only thing the DIC will show is the odometer and tripometer. it will not show anything else at all. if i push the steering wheel buttons, nothing changes from the odometer showing. is there an easy fix to get the DIC working again? Also, we dont have a remote for the doors and i tried the key in the drivers door lock and it just turns left and right doing nothing. is there an easy way to disable the door locks so that the lock/unlock button won't work? i pulled the under rear seat fuse for "locks" and the "lock" and "unlock" relays but the button still operates the locks. Thanks for any help!
