Have a D6N LGP that the parking brake will not release on. Cat technician recommended replacing the main wiring harness as it showed signs of corroding. Replaced it and three solenoids on valves. Still will not releasing. Technician thinks it is internal now. I'm at $12,000.00 dollars repair bill and no closer to getting issue resolved. I took the valves apart and cleaned them thoroughly, making sure the screens were not plugged with debris, made no difference. Has anyone dealt with this issue before? Serial number is ALY02368
