Exclamation CLIMATE CONTROL UNIT NO POWER ... AC FANS HIGH SPEED
I have replaced the climate control unit for 5 different ones, from glk 350 to c350. they all work and still ....sometimes there is no power to the control unit intermitly ( Radiator fans come on immediately when the control unit loses power)


This can happen when driving also with rear defrost on. starting to think its the AC pressure line faulty to tell the radiator fans to turn on constant... which then tells the control unit to show off/cut power

has anyone figured this out. climate control unit and fuses are not the issue....
