cavity "A"should have battery voltage when switch is turned on.wire is blue.look under your seat for this connector,back probe after turning onswitch.if you have 12v.thru your test light.then you narrowed it to the seat.moe

 

that helps. Thank you very much, Moe. I'll try it at weekend.

now I found the issue:
I had to strip the leather cover. Under the front part one canfind somewires: 2 black wires and two very fine blue wires, which go to the heat sensor. When I bypassed the two black cables, the heating worked well. So I suppose that the heat sensor was damaged. So, I dont need the heat sensor. I switch to 2, 3 or 4, thats hot enough.
