Default Heated seat always on

Little issue the passenger seat appears to be on all the time. The light is on in the switch and it I press the switch I hear the relay click but it latches again.
guessint I have a shirt to ground somewhere. Oh and by the way the seat isn’t getting warm so I imagine the seat heater doesn’t actually work.
I don’t want to leave a shot to ground though.

anyone no where the seat relay is and where the wiring runs ?

Its easy to follow if you feel where they go, just for starters I'd pull the fuse now to avoid unexpected fires. My truck had a similar issue but the heater was working to the point of heating the wires to skin burning temperature.

What year is your car that will help us answer questions.

Not sure what model you have but on my '88 the relay was on the LH component panel and had a slew of brown/yellow wires. The relay provided voltage for the heaters and the lumbar pumps. From there the power went to four separate fuses which should be labeled
