Expert:  Daniel Wilson replied 3 months ago.

So what are all the symptoms and chain of events that happened when this problem started?

Expert:  Daniel Wilson replied 3 months ago.

Im on EST here. It is 1:45AM I am logging out for the night but we can follow up as needed. For starters test all fuses for power on both sides with the key on and replace any with power on only one side. Check all relays by swapping with a known good one. Check the wiring and connector pins in the park brake circuit for damage. If okay, using an OHM meter test the park brake switch and the wiring. Also verify voltage to the park brake solenoid. Let me know the results and if we need to dig deeper into this.
