Correct Operation of Heated and Cooled Seats

Some customers may report that the heated seats operate for only one to two seconds and then turn off or stop working. The cooling function of the seats, though, is fully operational.

In you encounter this concern, ensure that the customer is leaving the heated portion of the switch on for five to ten minutes. Some customers believe the heating function is not working correctly because when the seat is commanded to the hot position, nine volts is sent to the blower motor for only two seconds. The voltage then drops to seven volts. This gives the appearance that the seat blower motor is only working for a short time and then shutting off.

When the seat is commanded to the cold position, nine volts is continuously sent to the blower motor. The sound of the blower motor is easily heard when the radio is off.

This is normal operation of the heated/cooled seats. No repairs should be attempted for this concern.

If you determine that the heated seats are not functioning correctly, check for loose, bent or backed out terminals at connector C305 (under the right front passenger's seat). Ensure that terminal A11 (dark green wire) is fully seated into C305. Repair any terminals/connections as needed.
