megane 3 1.5 dci 3.4 delphi AC problem - skyrimzz - 08-11-2023
hello guys,we have megane 3 here with manual climate control and Variable displacement compressor.we cant get it working and wiring is ok.valve is good,compressor also,wiring is checked and it is good.in climate control we have to parameters (evaporator temperature is good)
1.ac forbiden with ecu yes .when we press ac button this doesnt change to no and it should
2.request from AC yes when we press button and when we depress says no..so that is ok
we have 6 bar of pressure and coolant temp is ok in ecu
and both are measured in ecu
1.request for AC is undetected
2. permission for AC also undetected
we have solenoid valve that gets +after ignition plus and signal wire..both wires goes to upc and they are good..does this climate work on this car with ground..voltage is constante but upc sends ground based on info of ECU?canbus is also ok on car,both of them..information between upc and ecu goes by canbus?ecu is measuring pressure of refrigerant and temp of coolant..
all the wires are tested .even wires that go from ecu to pressure sensor..does anyone has idea why it isnt working?
