I don’t know if my heater just works super quietly or if I’m deaf or if the following consideration is possible at all: Because of a defective heater I was at Volvo and had the error fixed. Heating now also works 1A. However, I have the feeling that the part does not work as a heater at cold temperatures. At least I don’t hear anything there. In the V70 of my parents, the heater also runs after a few seconds (at least I imagine that this is the heater). Is this technically possible at all?
