'15 LX570 - Cabin air blows cold. Thermostat? (1 Viewer)

[LXGus]

My cabin air blows cold until I turn the temp up to HI. It then blows hot. But even at 75 it still blows cold.

My coolant was flushed recently and is full. The engine isn't overheating. Has anyone had this issue? Is my thermostat bad?

I doubt it’s the thermostat. With the recent coolant flush there is a possibility of air in the system and the HVAC is not getting proper coolant circulation. Another possibility is the cabin filter recirculating/fresh door is broken and causing the HVAC to freak out. Yet another possibility is the HVAC servos (motors) need resetting/recalibration. I suspect one of those 3 things is the problem. Run a search on google using those issues plus 200 Land Cruiser plus ih8mud and you’ll get some actions to take.
