Nope, its not the switches. When turned on, they both trip a relay under the dash. Someone told me to pull the connector under the seat and test the 2 black and red wires for resistance. Problem is, there'* only one black and red wire, and once the connector is pulled, no power is applied to the wires. It must have to complete the circuit. Anyone know the color of the wires going to the elements in the seat, so I can rule out the elements at least??? Thanks fellas!!!

There are four wires in the connector that is between the under-seat module and the heater elements. On the element side of the connector the red and black wires go to the elements and the two grey wires go to a thermister that detects an over temperature condition. Check resistance across the red and black wires and it should read 2.4 ohms.

If you are checking resistance across the red and black wires in the connector leading to the elements and getting an open circuit you have a break in heater element wire. There is a complete circuit from the red to the black wire that passes through 3 sections of heater element, each of which has 0.8 ohm resistance.
