Has anyone ever gotten the ghost in the seat heater (drivers)

It seems to turn and off by itself a lot....,....,I turn it off and literally in 2 seconds its full blast heat...

Then today, it goes up and off like a light show,..,, we replaced bcm last year..,, and ebcm.... What would be good to look at for next issue ?


Thanks

Yes mine does this.  I thought maybe it was a water/short in the wiring harness at the bottom of the drivers door.  Have not figured it out.  Happens most when it rains or is wet out.  Dry days seem to be just fine.
