SOURCE: Heater blows cold air when idle

Sounds like you may have a partially plugged heater core. You could flush this out separately, from flushing radiator & engine block. Diconnect heater hoses going to your heater core and clamp off, so not to loose coolant from engine. Now hook up separate hose to one side of heater core pipe and flush out with typical garden hose. Repeat procedure on both heater core inlets. Reconnect original heater hoses and test difference. You may have to add an additional litre of antifreeze. If this don't work i suggest changing heater core. Good luck.........Ron.

SOURCE: Heater blows cold air unless accelerating

See my posted question under 2001 Mercury Villager: "HEAT BLOWS COLD WHEN CAR IS IDLING" I got an answer from chuck943 about air pockets and it was very helpful.

SOURCE: AC blows warm air at idle

your a/c fan may not be working or slow, if not then your compressor is starting to fail. you could save it by changing the freon and compressor oil, if not the you have to change it.

SOURCE: air conditioning not cooling while driving,works sitting still

If the air blows normally but warm, then you need to check the compressor and its gas. you might have a leakage.

Heater on 2007 Suzuki vitara blowing warm air only

windows fogging up
well that takes 2 things working to do that 3 really
1: heat, you have heat. and blower works.
2: you need the dampers to work, to send a/c side air to the windshield. (it mixes heat and a/c flows)
3: the A.C must work it is the DEHUMIDIFIER PART.

i do not understand at all the sticking thing,
are you saying the controls are failing, ?

Heat issue

Chances are your coolant level is low or an air pocket is present in the cooling system.

I have no heat at idle on 2007 grand vitara but good heat when driving.

Sounds like you are getting poor water circulation, have you ever had to change the water pump? I have in rare cases seen the impellers erode away on the pump and it was no longer able to move water around the cooling system correctly.

Heating and air

My first thought was low coolant, but with the added point about the ac I'm leaning toward a blend door problem under the dash.

Long time before heater blows warm air

That seems pretty normal, the heater works by blowing excess heat from the engine coolant. So the coolant has to be warmed completely for the heat to work, you can get a heater that plugs into your cigarette lighter that will heat the vehicle instantly.

No heat when car sits idol, only when moving.

is this your first car?
I will presume the fan is running at full speed and heat max is set and the that you tried recirc lever. fresh air is less heat...
Cab heat bad. right?
only when moving, what?
Ill guess that no heat sitting idle for 30mins. TIME MATTER.
as does time of day and if first start of day and if the ambient temperature (out door temp counts, and guess what no country or stated told so i cant look it up, me fail)
first off,
the modern engine can take a huge long time, to heat up dead cold and not driven , that is why the op guide tells you,
start car ,wait 45 seconds and drive off slowly,
the warms the engine fastest , saving 90%of all engine wear.
this is proven fact by Germany long ago and now with
hard fact.
now if you know the car warmed faster before.
then this is possible 2 ways.
1: bad thermostat. (slow)
2: or the engine is running so bad, that the heat to the water jackets are weak.

the cab heat will be the same as the engine water coolant
if the engine is cold, so will you be. hard fact.
there are no electric air heaters here...

here is a frozen air page.

2 tests.
1: does the engine hit 180F or more and hold?
2; does it do that , at the same speed, as when new?

if not we trouble shoot that first. (fan works, and blows)
