Thank you . Have you checked the fuse panels both inside one and outside one to be sure that all fuses are in the proper locations according to their charts and that all fuses and breakers are good ? I will look up the diagrams for the park interlock system

Customer: replied 1 year ago.
I have. This is an intermittent problem.
Expert:  Andy replied 1 year ago.

Under Normal conditions , if you can hear the park interlock click when you step on the brake pedal , then try this : Have an assistant step on brake pedal with key on , while you go ahead and wiggle test the harnesses from battery box up to power panel outside and harnesses around tranny area to see if the assistant can hear the park interlock solenoid clicking .

Didnt do anything and it started working
Customer: replied 1 year ago.
Are there any common power wires that have to do with the turn signals, guages, horn and shift interlock?
Expert:  Andy replied 1 year ago.

Yes all ground wires are colored white and all attached q ground studs on the firewall in the lower left of the dash

Expert:  Andy replied 1 year ago.

The ground studs are located behind the body controller which is behind the left kick panel

Customer: replied 1 year ago.
Well, I asked about power wires but the grounds look ok. Clean and tight. Now what about power wires?
Expert:  Andy replied 1 year ago.

These would all likely be controlled by the body controller . Have you checked the connectors at the body controller for corrosion ?

Expert:  Andy replied 1 year ago.

If you would like to continue this using Skype , I can likely offer more assistance that way with the proper diagrams according to the build date of the truck . I can also explain better in an a.udio chat how to find the problem .

Customer: replied 1 year ago.
Ill check those things and if I dont have any luck we can try skype
Expert:  Andy replied 1 year ago.
