I am trying to troubleshoot my 2003 1500 4.7l HVAC/Climate control issue and can't seem to find any information for the symptoms that I am having. When I turn the knob to turn on the climate control, nothing happens, nothing turns on at all. However, if you push the A/C button, it will light up, but again nothing happens. For awhile it would do this once in awhile, then work normally. I have checked all of the fuses and relays and they are functional as is the Blower Motor Resistor. Would it be the Climate Control unit itself? Could it be the A/C Compressor? Or is it something totally different? Any help would greatly appreciated!
