Cooled seats just quit. Need troubleshooting help


Recommended Posts

2007 Escalade ESV.

The cooled seats just quit. Im sure they are not too different from the car versions. So has anyone troubleshooted these? I see a fan below the seat and a wire harness plug but nothing corroded or unplugged. Fuse is good. Both seats quit working. The heat and all other power works. They say you should hear the fan(s) but I dont hear anything.

The cooled seats option RPO code is KB6 on the 2007 Escalade ESV, for those looking for information or parts.

The 2007 FSM shows a fuse, a 10 Amp MISC IGN 43 fuse, in the underhood fuse block that supplies power to the module. A separate 30 Amp COOLED SEATS fuse provides power switched to the cooling elements and fan.

Since both quit at once, these two fuses and the connector to the seats HVAC module are the best places to start. Next would be the switch, but I think that there is a separate switch for driver and passenger seats.
