heated seats

hello, got a 02 slt with heated seats. the drivers seat sometimes heats up and sometimes does not. has anybody else had this problem? i think it is the switch but i am not sure and dont want to spend money for a switch if i dont have too...thank you


also have a cracking sound when i am about to stop . it comes and goes as it likes and it comes from the drivers front, i think i read somebody elses thread about this problem....
again thanks in advance
