hello. yesterday I had my climate filled. the last time was in 2002! was so with bosch.. and I was already looking forward to it finally working.. but that’s not how it was. the electrician said that the compressor does not get any current.. but if he takes out the relay and a cable from the plus pole of the battery to the plus contact of the relay for climate pulls then she goes.. so I don’t want that.. that’s total fusch( she always runs.. and with a switch I also want it can you help me? what can that be…??
