Passenger side heater blows only cold air

I have a 2009 Chevy Impala. When I use the remote start the car starts but the heat does not come on. The heater gauge is on. Can you tell me the problem?

The car starts but the heater blows cold air and does not heat until I put the car in drive.

Yep, got a new actuator for $87.00 heat is nice again, been cold for too long :)

I get no heat when at an idle, but the heater workds great when moving at highway speeds. I've replaced the water pump and thermostat.

Had the same problem, took it to the dealer, they had a replace two gaskets on the crossover pipe an the theromostat, all covered under warrenty. They knew of the problem but only repaired it if you took it in.

2008 Chevy Impala. We get NO heat when the car is idling. We we use the remote start the motor warms up but there is NO heat to the car. When we start driving then we get normal heat, until we stop at a stop light. Then brr cold air. What could be the problem?

Car made clicking noise under dash couple of days ago now heater only blows cold air, no heat at all

I have a 2008 impala 3.9 we bought new in 2009 and has about 65k on it.

To start, this past winter the heater would blow only cold air and would not warm up until 15 minutes into a drive. Even when idling for 30 minutes, the blowing air would still be cold until that 15 minute mark.

Last week, 5 minutes in to a short drive to the grocery store, the temp needle shot from the middle to the highest point, the temp lite came on and the dash message said "engine overheat idle engine". 5-10 minutes of continued driving and everything goes back to normal ( lite off, message gone and needle to the middle). This happens every time we drive now, and seems to happen every 30 minutes on longer trips.

Today, as my wife is driving to work, every light and dashboard message went on for a few minutes while driving and shortly after, went off.

Any advice? Thanks in advance.
