Recommended Posts

Hi Everyone,

I'm a new member who has just purchased a 2006 Avensis 2.2 d4d T180 estate and have a problem with the heater blowing warm on driver side and cold on passenger side. I found an article on self diagnosis of the system and ran the checks, it came up with error codes 21,24,41,43 and 46 can anyone tell me what these codes are relating too.

All help greatfuly recived.

Can't help with codes but there are quite a few threads on here about similar problems.

The problem is most likely a bad dual climate control valve. This component is located on the right side near the radiator under the hood. It will have several coolant hoses hooked to it and 2 silver cylinders protruding from it. You can clamp off the heater hoses at the heater core and see if both sides cool then and this will tell you that the valve is letting coolant thru when it shouldn't be.

This will narrow it down to either the valve or the control head inside the car,or wiring in between them. The only way to narrow it down further is if you have a scan tool that could access the climate control data. Have seen several of these valves cause this concern and have only seen one control head cause it.
