Heater System Coolant Leak Affecting Electrical Systems – Jeep Renegad
I was experiencing an issue where the coolant level kept dropping without any visible external leaks. Eventually, I identified the cause as a failure in the heater system behind the dashboard. There was no coolant leaking inside the cabin; instead, the coolant appeared to be accumulating or evaporating behind the dashboard area.
After this issue, several warning lights started appearing, including the airbag, electronic braking system, and seatbelt indicators. I suspect these warnings are related to coolant or moisture affecting electrical components behind the dashboard.
I would like to know how and where I can safely clean the affected electronic parts, or which components should be inspected first.
Vehicle details:
2017 Jeep Renegade Trailhawk 2.4L
Any guidance or experience with a similar issue would be appreciated.
