Have an 03 EB and I have questions about the seat heater. Mine work (although they're not very hot), and they shut off after 20 minutes or so (normal operation). BUT, I can't then turn them back on. The only way to re-activate them is to turn off and re-start the vehicle. Any ideas? Also, is it normal that they don't get very hot? I've used the ones on a GM product and the seat gets VERY warm, but mine are not noticably hot.
