I have an 05 tsx with auto climate control, no nav, and on very cold days the automatic climate control doesn't seem to work. I think the problem might be with the outside air temp sensor. The air temp reads 10+ deg higher than what the weather channel says the temp is. The coolant level is fine and if I switch out of auto, I get heat no problem. I just can't maintain, say 70, cabin temp in auto. Thanks for any input or ideas.
