Jeep TJ Wrangler Blower Motor Relay Test

The Jeep TJ Wrangler (2000) blower motor relay is located in a wire harness connector that is secured to the heater – A/C housing behind the glove box on the passenger side of the vehicle, next to the heater – A/C wire harness connector in the passenger compartment. Remove the relay from its connector to perform the following test. Jeep TJ Wrangler Blower Motor Relay Test A relay in the de-energized position should have continuity between terminals 87A and 30, and no continuity between terminals Read more […]

Simple Relay Circuit

The following schematic illustrates the Simple Relay Circuit Diagram. When the switch is opened, the current flow through the electromagnet ceases and the magnetic field collapses and disappears. Since the attraction for the soft iron bar by the electromagnet no longer exists.
