Asked by Aug 10, 2010 at 03:17 PM about the Chevrolet Silverado 1500

Question type: Maintenance & Repair

The display on the hvac module has went blank and is not responding when I push the buttons.  I checked the fuses, underdash electrical connections and tested my module , but cannot find anything wrong.  Any suggestions? Thanks in advance

if its got an aftermarket radio, there's a chance the antenna adaptor fell on to the circuit board of the hvac head unit shorting it out...if thats what happened, replace the head unit and wrap the antenna adaptor in electrical tape so it doesnt happen again.
