DIAGNOSIS AND TESTING - HEATED SEAT MODULE

If a heated seat fails to heat and one or both of the indicator lamps on a heated seat switch flash, refer to Heated Seat System Diagnosis and Testing in Heated Systems for flashing LED failure identification. Refer to Wiring Diagrams in for complete heated seat system wiring diagrams.

NOTE: Any resistance values (ohms Ω) given in the following text are supplied using the automatic range generated by a fluke® automotive meter. If another type of measuring device is used the values generated may not be the same as the results shown here, or may have to be converted to the range used here.

RIGHT SEAT HEATER INOPERATIVE

NOTE: If the right seat cushion is already warm the following step will not prove conclusive.

NOTE: Be certain the battery is fully charged before testing. Failure to do so can result in incorrect readings.

LEFT SEAT HEATER INOPERATIVE

NOTE: If the left seat cushion is already warm the following step will not prove conclusive.

BOTH SEATS INOPERATIVE

If both seats (driver and passenger) fail to heat and the indicator lamps on the heated seat switches for both seats fail to operate, test the heated seat fuses in the junction block. If the heated seat fuses check OK, go to STEP 1.
