:yes: i have a 2009 impala ltz love my car.
i need help trying to find out about a problem with the heat.
Whwn in idle the car blows cold air and it takes a long time to warm up.
any ideas please post.
Assuming your car is not overheating and gauges are reading normal, feel the hoses going into the heater core. Both hoses should feel about the same temprature, if not then you have a blocked heater core.
If hoses are the same, then it could be your heater resistor, which is a DIY if you have a repair book to show you where its located.
And finally if all the above is good then its your blending door that could be stuck or broke.
