your blend door which cost about $1000-1500
If there is no heat coming out of the vents, but there is air coming out on a 2003 Mercedes Benz E-320, check the thermostat to make sure it is not sticking. If this is okay, check the heater core. If the heater core is bad, there will be water on the passenger side floorboard.
It means you have a leaky heater core. You may also find the front passenger floor wet with engine coolant.
Could the heater door actuator be bad? What is the cost to replace? This Grand Prix has a dual-zone climate control and when the AC is on, the passenger side vents often change to heat when the control is still on cold.
what i am assuming is being talked about is that when you go to turn on the heat in a Seville, heat will only be produced out of one side of vents. there are a number of valves in a Seville which control wether the air that is coming out of the vents in hot or cold. in a Seville there are a pair of these valves one for the passenger side air, and one for the driver side air. the reason why only one side of the car is blowing hot air is because one of these valves has gotten stuck in the "cold air" position and needs to be replaced. the same thing happened on my car but the drivers side was the one not blowing heat.
Perhaps a dead mouse.
mine is doing the same. i have already bled the cooling system of air, checked the trap door motor for proper operation and still little heat comes out the vents. im leaning towards the inside thermostat for the climate control. its located between the vents on the passenger side. im stumpped too!
my 2000 Chevy venture van the air comes hot by drivers vet and cool by passenger vents
Front heater core is in the dash, the rear heater core is all the way in the back of the vehicle. If you have steam coming out of the dash vents, the front HC is leaking. If you have steam coming out of the rear heater vents, then the rear core is leaking.
When i disconnect my battery and reconnect it and then turned my heat on it works for a minute. And then it seems like it makes heat on the driver side and air-conditioning on the passenger side. It has climate control for the passenger.
um...I know why no one has answered this yet, cos no one knows what the heck you are talking about!! Try rephrasing it!!!!!
check and replace if needed the heater core that's one reason why no heat
Sorry bad news Your heater core has a leak
