What is the best and cheapest way to repair seat heating element(s)? on 2004 Cadillac DeVille

Regular (non-dealer) repair guy says it's not a fuse but the element and referred me to auto upholstery guy. Upholstery guy says it's an electrical thing, but he'll put in the element if I bring it to him. Been trying to get the part(s) numbers so I can track them down, but for some reason that's proving difficult. Any ideas?

Remove the seat and bring it to an upholstery shop. Let him remove the heater element and then you can check it for continuity and resistance, part # will be on unit. Bring him your new one (I do not recomend used) . The dealer should not require a part number. Let the upholstery shop assemble the seat and you reinstall it.

good luck
Great ideas all around. Thanks a ton!
