Hello! I would have such a problem that the 2013 508 2.0 HDI produces error codes p0691 and p0693. The fan only works at low speed when I turn on the air conditioner, not at high speed. However, the air conditioning temperature is not suitable when stationary. The cooling fan controller was replaced with the factory one and the fuses were also checked. The problem persists. Can someone help me with what else could be the problem? The water temperature sensor is also good and the air conditioning compressor switches on. It was also freshly filled with gas. The only thing missing is my high fan setting.
