HEATED SEAT ELEMENT
NOTE: For complete circuit diagrams, see Wiring Information. Wiring Information includes wiring diagrams, connector pin-out and location views, details of wire harness routing and retention, splice and ground locations and proper wire and connector repair procedures.
The wire harness connectors for the heating elements are located under the seat.
NOTE: When testing the heated seat elements for resistance, be certain to sit in the seat in question and move around the heating elements within the seat while testing. Moving the heating elements will help eliminate the possibility of an intermittent open in the element, which would only be evident in a certain position.
1. Locate and disconnect the seat heating element electrical connectors as necessary.
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 bottom element and 4.3 - 5.4 ohms for a seat back element. If OK, test the Heated Seat Module (HSM) and related circuits Testing and Inspection. If not OK, replace the inoperative heated seat element Heater Pad - Removal.
