Im thinking short to ground somewhere in your heater harness unplug the connector and see if either of the 2 heater wires have ground with a test light I don’t know if the ppm side should because I believe in a key off state there should be no ground side switch

I would look in the direction of a vacuum leak, check to see if your fuel trims get better with rpm if they do most likely a vacuum leak.
