Circuit Breaker: Description
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
Automatic resetting circuit breakers in the junction block are used to protect the power seat and power window system circuits. These circuit breakers can protect the systems from a short circuit, or overload condition caused by an obstructed or stuck seat adjuster, window glass or regulator.
The circuit breaker cannot be repaired and, if faulty or damaged, it must be replaced.
