Failed seat heating elements are fairly common. I have also seen several failed seat control modules. Access to the data from the Body Control Module and the Seat Module is necessary to perform an effective diagnosis.
First off, I would contact your local Jeep dealer and have them run your VIN # to check for any recalls. The 1999-2004 Grand Cherokees had a recall on the seat heaters. If your vehicle doesn't fall into the VIN # range then either your seat heater switch has gone out, or you have a broken element in the seat heater. I have replaced more seat heaters than switchsm the elements heat up and break. Hope this helps out.
Try this remove the ckt breaker for the power seats the ckt breaker is located in the fuse box inside down by the drivers left foot. leave breaker out for about 10 seconds then reinstall it and see if the seat starts moving. If it does there is a reprogram for this and needs to be done by a dealer or someone who has access to be able to reprogram your vech.
several things could cause your heated seats to not work. If the seat and heated seat seat stopped at the same time could be the reprogram could fix it. If the heated seat quit working at a differant time it could be the seat heater element. get a schematic of the heated seat and ohm the wires for the element. If either element tests open then the element will need to be replaced. You might as well replace both of them at the same time since the seat covers have to come off to replace the seat heaters.(back and bottom ) If one element is bad then both heaters quit working.
you need to check the resistance in each of the heated seat elements in the seat. There's a two wire connector under the back of each front seat. The connector should be green. disconnect it and measure the resistance along the circuit going into the seat. if it isnt .1 - .3 ohms, replace the appropriate heated seat element
Could be that the wiring for the heater is broken, or that the heating element itself has been damaged. Has anyone knelt on the seat when reaching in to get something out of the car? Or has anyone stood on it (a child maybe)? Pressure like that can break the heaters and keep them from firing up.
