I just changed out my 03 5.7Hemi wth an 04 5.7 Hemi. I got it all buttoned up and everything put back where it belongs. The issue that I am having is that now my Airbag, ABS and Brake dash lights are on. My speedometer does not work and my HVAC panel doesnt work. This happened to me once before and I change the spreed sensor on the rear diff with no success so I drove it for a year asking everyone I knew for suggestions. I finally spoke to an older gentalman that told me to replace my electronic ignition switch and 27 dollars later my problem was fixed. I tried that same trick again but it did not work. I have checked all of my fuses without finding one that needed replacing. I checked all of the prongs on the receiver to make sure that I was getting good contact. Any suggestions would be wonderful.
