Grand Cherokee 2WD V8-5.7L VIN 2 (2005)
Seat Heater: Testing and Inspection
Heated Seat Element
The wire harness connectors (2&3) for the heating elements are located under the seat (1).
NOTE: When checking heated seat elements for continuity, be certain to move the heating element being checked. Moving the element, such as sitting
in the seat will eliminate the possibility of an intermittent open in the element which would only be evident if the element was in a certain position.
Failure to check the element in various positions could result in an incomplete test.
1. Locate and disconnect the seat electrical connector.
2. Check the resistance between the circuit leading in and out of the suspect heated seat element. The resistance should be between 3.8 - 4.8 ohms
for a seat cushion element and 4.3 - 5.4 ohms for a seat back element. If OK, refer to testing. If not OK, replace the inoperative heated seat
element.
