SOURCE: coolant resevoir

There is a feed hose under there that goes to the bottom of the reservoir. Look around the edge of the reservoir, and you'll see three locating screws, philips head. Remove these and you can tilt the reservoir up and out of the way to look and see if you can see a disconnected hose underneath.

SOURCE: audi a6 heaters not given out hot air

the heater cores in these cars get clogged up very commonly. pull the heater hoses off of the heater core in the engine compartment, and use a regular garden hose to backflush the heatercore. spray in one way, then the other, untill clear water is coming out. then refill your coolant reservoir and see if that helps.

SOURCE: 2001 Audi S4 Heater doesn't work

Thermostat has failed (stuck open) and needs replacement. It's a big job (5-6 hours charged labor for a shop), and requires the front of the car to be removed. Here's a pic of my car (B5 A4) a few weeks ago when I changed mine:

There's no way around it either - removing the front of the car is the only way to access it.

Only warm air in def no heat elsewhere

check the mechanism that controls the heat flow .The flap may not be opening fully thereby ,impeding the full flow of heat into the cabin. .

Audi a4 2.8l no heat

take the top off the filler cap run engine to boil. keep it full off water to the top. you will see air bubbles coming out as the engine gets hotter. squeeze the pipes on the rads to help the air come out. when fan kicks in turn engine off and leave to cool down.while you are doing this make sure the fan for heater is off but is on full heat. can have fan on number one on speed that is fine.

I just bought a 2000 4x4 Dodge Durango. The temperature gauge reads properly at about half way, but the heat blows air that is not really hot even though I have the heat at maximum warm. What is the...

try feeling your heater hoses going from the engine to the heater core. they should be hot at operating temperature. If one is hotter than the other noticably it would indicate a restriction in the core most likely. A partially stuck thermostat could also cause loss of heat but you say the temp is normal. Start with checking hose temperature if they are both on the cool side compared to the radiator hose then further diagnostics are necessary. hope this helps. Keep in touch.

I believe its the thermastat but I will tell you what my problem is so I can get the proper analysis. I have absolutely NO heat at all. Trying the thermastat replacement is the first thing I should do...

i wish you luck but is the temp staying in the usual place on the meter... could be as simple as a heater coil. or maybe the electronic control is not changing to flow water to heater core.. check engine light on?: turn heat on off on off on off to try to get it to change flow.. good luck

When truned to heat no heat but ac works great

Check the heater hoses going into the heater core.They should both be hot to the touch.If not then check your cooling system for rust.You will probably have to back flush the cooling system.Just remove the heater hoses and take a garden hose and put it on one of the hoses.Then on the other and when the water comes out clean you are done.eventually you will have to replace the heater core but this will get you by for awhile.Good luck.

1996 audi a4, no heat.

Sounds like your thermostat is sticking open, when this happens your coolant in your engine isn't given enough time to warm up and just cycles threw to your radiator, which cools the fluid not allowing it to get warm/hot. Thermostat tend to go bad, this is most likely your issue, just have your thermostat and gasket for your thermostat replaced too. Your looking at about 10 dollars in parts maybe 20 dollars in labor! If this helped give me a thumbs up please!

Temp. skyrockets when turned to heat

That cap theory does not sound right...check for a heater control valve in-line on the heater hose and make sure than is opening and closing. I'd also disconnect both heater hoses, hook up a harden hose to one of them on the heater side and flush out the core.

you have air in the system!! you have to unbolt the filler tank and lift it 5 inch higer first. then loose the right hose on the heater core( this hose have and hole to bleed the system) and then put antifreeze until the antifreeze will go out of the hole then re install the hose to the heater core, then ajust the level correcty
