heated seats on 2004 Chevrolet Tahoe

what is causing my heated seats to kick off. If I only have one on it does not kick off, but if I have both on they will kick off

If they are supplied power by a circuit breaker, then you may have a problem with the circuit breaker or the circuit is drawing too many amps with both heaters on, which might be from one of the heating grids in the seat.
