Hi guys.
I have terrain 2014 3.6l.
After the winter I realized that ac not giving cold air. It blows only warm. First of all I that that there is no refrigerant in the system but after I checked it with mechanic it was ok. When I turn on the ac led button in switch on, clutch with compressor starts, but low pressure line is showing around 80psi as the hi pressure. We’ve changed expansion valve, hi pressure sensor, relays and ambient outdoor temperature sensor. Checked fuses and cabin temperature sensonrs. All works. Refill refrigerant in the service. It still blowing only warm air from outside. Actuators works fine a can regulate from hot to outside temperature, but not cold air. The main problem that I have right now that I have 2 fans on radiator and when I turn on the AC condenser fan not starting. But if I’ll disconnect rellay it will turn on both of them so the fan is works. Before the winter when I was turning AC in autumn it could start randomly like from the fifth time sometime from the first. In summer it was ok. Looking for suggestions in searching the problem. Thank you.
