Sal,
The seat heaters both work off the same (2) fuses. #17 (10amp) and #40 (15amp) in the I/P fuse box. If the 10amp is good but the 15amp is NOT, the LED indicator WILL light but the seats will NOT heat up. The 15amp fuse supplies the power for the seat heater module located under each seat (they're basically the thermostats for the seat heaters). I would start by checking BOTH fuses, then check under the seats for bad connections. I will assume the ground is good because both seats share the same ground and since the LED comes on, that should indicate that the ground is good.
