Tim Rucker Posted December 1, 2022 Share Posted December 1, 2022 I have a 2008 Lexus GX 470. Gifted from my father in-law. The car only blows cold air then the auto temp is set to LO. Adjust temp up 1 degree and it then blows HOT air. He did have the dash replaced some time back so not sure if something happened then. Now in winter.....units blows hot sometimes and cold sometimes.

RX400h Posted December 2, 2022 Share Posted December 2, 2022 You might want to have the coolant flushed/replaced. Sometimes an air bubble will slow down or stop coolant circulation. Quote Link to comment Share on other sites More sharing options...
