driver side heated seat doesnt work on 2002 GMC Yukon XL Denali

when you push the button to turn it on, it does come on. you can turn it on low and high. It stays on too like it should be working. It doesnt flicker on or off or switch from high to low by itself but the heat itself does not come on.
