A 1997 Chrysler LHS may keep blowing the 20 amp engine controller fuse due to a short circuit in the wiring harness, faulty sensors, or a malfunctioning engine control module (ECM). Additionally, damaged insulation on wires or issues with connected components like the fuel injectors or ignition system can contribute to the problem. It’s essential to conduct a thorough inspection of the electrical system to identify the root cause and prevent further fuse failures.
