2005 Yukon Denali Heated front seat issue - just clicking

[Soma1975]

So I have an issue with my front heated seats on my 2005 Denali. When I try to turn on the seats at either the driver or front passenger control, all I hear is a clicking...almost sounds like a relay clicking.

Is there a wiring diagram for the heated seat system? Guessing some sort of master fuse or relay is bad. Any other suggestions welcome.

Thanks in advance !

Do the lights come on then go back off by themselves?

lights don't even come on....I'm really interested in the schematics...

Mine does the same thing except the seat warmer lights come on then turn off, any ideas? Could they be the same relay, if so does anyone know which one it is?
