In a 2006 Acura MDX, the heater control valve is typically located near the firewall on the passenger side of the vehicle. Connected by hoses that lead to the core, this valve can often malfunction, causing a lack of heat in the car. Replacing the heater control valve can cost between $250 and $350 when done by a mechanic. If you suspect a failure, it's important to have the valve checked and replaced if necessary after verifying the hoses and fuse are in good condition.
