What causes pcm fuse to blow on 1997 breeze?

The PCM (Powertrain Control Module) fuse on a 1997 Plymouth Breeze can blow due to several reasons, including a short circuit in the wiring harness, faulty sensors or components connected to the PCM, or excessive current draw caused by damaged electrical systems. Additionally, moisture intrusion or corrosion in the connectors can lead to electrical issues that result in a blown fuse. Regular inspection of the wiring and connections can help prevent such problems.
