My 04 has heated seats, although they are not working at this moment. The GM dealership says the resistance is too high. I believe the seats are tied together, so if I disconnect the bad seat would the other still work? Is this even an option. If it is where would I disconnect it? The labor cost to replace the elements in the seats is big $$$$. I think the total cost including parts is > $800.00. Has anyone else experienced this?
