1995-2002 Range Rover P38A
I understand that this has been covered a lot, and I have looked around at this for the past year and a half. Here is what I have. 2000 HSE 4.6 p38 with 95,000 miles. my heat worked 2 winters ago. Since then, I have installed a new HVAC control that the lcd is now going bad on again. I have also replaced the radiator. Only cold air, on both sides, all the time. I can turn the ac compressor on and off, and when it is on and the heat is set to max it blows the ice cold ac through the vents. When I have it set to max heat and have the ac compressor off, it just blows unheated air. I can move the air from floor, defrost, face level, etc with no issues. I have a brand new functioning thermostat with hot coolant flowing in and out of the heater core. I have the coolant flow running as it should with the radiator bypass hooked up. it gets to operating temp fast and stays there. I checked my heater core temp sensor and it was not corroded at all (can I bypass it for a test?). I have checked both fuses 8 and 17 and they are good. My heater is basically inoperative, I can get no hot air anywhere at all? Can the climate control unit be at fault for this?
