I bought this new (2009) and have trouble getting heat right away. I drive the car 3 times longer than any other car before it heats up. They claimed they change the thermostat on it but it still does the same thing and they are scratching their heads. Anyone know anything. I sure could use the help. I have noticed that as long as I keep the blower down to 1 or off the heat will slowly come up and eventually go to hot but if I raise the blower to high i can see the heat gauge do down some and eventually never go back up again until I shut the blower of. Is it posible to put the thermostat in backwards??
