Success! After changing the the PCM (fuse/ relay box) to correct the "no park lamp" issue my brake lights stopped working and my shifter would not come out of park.
I went back and checked everything and found the Instrument Cluster-C2 connector (left side) was not seated completely. That's where the brake light switch signals run through.
I'm having a bit of a different issue. Have an '04 5.7 HEMI. Drivers side headlight only goes with low beams and passsenger side headlight only goes on with high beams. Also 3 out of the 4 blinker lights don't work. Checked all of bulbs with a meter and checked the fuses and relays. Parking, reverse lights and brake lights run fine. Looking at the Haynes wiring diagram all the lights with issues run through the forward control module or front control module (FCM). Paid close to $300 to the stealership and replaced, but still having the same issue. Do I have to re-flash it. Any help would be appreciated.
Update: I finally changed the power distribution center (fuse block) and it finally fixed all of my lighting issues. Apparently there is an issue with the chip boards inside the PDC that are known to corrode. I do not recommend getting one from an auto salvage since those will probably have the same corrosion issue.
There was nothing wrong with the FCM so I re-installed the old one. Unfortunately the dealership does not accept returns on any electronic components. Anyone interested in purchasing a front control module (FCM). Check out ebay links. I have a new one and used one. Part numbers are 56051036 and 56049681.
