Hello municipality I am a newcomer in relation to Volvo but must say that I am positively overwhelmed after my BMW, to the problem I have installed a new climate compressor (used) but the problem that the climate compressor does not get any current, the control lamp goes on when switching on the thre number goes high but the compressor remains off, current does not come to the compressor. I have checked the RE current arrives but I could not find any current output at the gray cable that from the RE to the compressor feeltr safety ok need help someone already had the phenomen and how is the aid, the friendly in the further city can not detect the missing memory its statement the connection to the fault spoke cannot be established, I am grateful for every advice. Best greetings PS. with window lifters I have problems from the front I can not control the rear outside of the HR but only in close position of nites can only be opened and closed to the dogs.
