In order to access the door u mention which is called the air temp control blend door u must remove the entire dash assembly, most likely the door's actuator motor is defective, very common part that fails.

2001 VW Beetle heater not heating.


If both your heater hoses are hot, the heater core is circulating fluid. If only one is hot, and one is cool-then the core is plugged or has an air block, or a valve in the heater line is closed if that applies.
If the engine stays at normal operating temperature, doesn't overheat at all, there should not be a problem with the water pump.

The problem may be with the doors in the heater case not operating properly.

No heat coming out and van overheating


It could be the thermostat or the water pump. Even if your heater core were plugged, the engine would not overheat from it, you would just have no heat. And if the thermostat were stuck closed, but the heater core was good, you would still get heat from heater while the engine was overheating. So it kind of points toward the water pump, unless neglect had allowed both the heater core to plug and the thermostat to stick closed. I mean neglect from not regularly changing the coolant every two years about.
Overheating can be as simple as a low coolant level, so you should check that, and check for leaks.
Before you go for the cost to replace the water pump, you should first have the system pressure tested, or have a compression test done to check the internal condition of the engine and to make sure you don't have a blown head gasket. Good luck.

There is no heat blowing ou of the vens on my van


The water must be able to circulate and there are three main things to stop this from happening.Heater core blockage,thermostat and water pump.
After checking those you must look at the controls under the dash to see if a dampener door is remaining closed.The doors will shut off the heater core from air circulation when using the air conditioning and vice versa. After starting the van switch the controls for temperature from cold to hot and listen for the door to open and close.That's where I would start.Also you have a Heater Control Valve that shuts off all hot water from entering your heater core.If this valve is closed you would get no to very little heat.It's located in the heater hose from the intake to your heater core.

98 chevy cavalier 2.2 L heater problem


hello.....
first in this problem you need to look for cheapest things to do which is start with you thermostat abd make sure its open and close by how much temp inside the eng. then u need to feel the input hose and the output hose which they come from the heater core they should have closely same temp . if there is non of them have any heat thats mean the water pump blower is broke and u have to replace the water pump, if one of the heater core hose hot and the other cold the problem in the heater core , about the A/C light is on the A/C comprasser shoul work with the heat becuase hot air + cold air = dry air which u need for ur front DEF
