Heater not working on 04 Audi A4

[GuessWho]

So it's blowing AC perfect, but now when I crank up the heat, air is coming out but just not warm ?!?!

Any ideas ?!?!

The dealership said it was clogged and that they couldn't clog it and that I would have to get a whole new heater core...... But we all know how dealerships are Jewish !

they are probably correct. if it is the core, theres really not a way to un clog it.

dealers are not jewish, especially when dealing with german cars...

take both hoses off of the heater core (inside engine bay, behind engine) and run water from a garden hose through the core. water comes out as fast as it goes in- good core. no water coming out- bad core.

also - what engine is this? 2.8 v6 or 1.8t? the 2.8's have a problem of getting an air bubble in the water passage from the heads that causes no heat- especially after something has been done requiring the coolant to be drained and refilled...

and - check your waterpump and thermostat.

^ Thanks, but dealerships are still Jewish bastards...
I ran water through it and everything was good... So instead of them charging me $750.00 to replace something I don't need... They're now going to check the Blend door which I'm about 100% sure is the problem.
Motor must of went out on it.
Anybody need a Heater Core for Audi A4 1.8t ?

yeah, you didn't catch my sarcasm regarding jews and a car company backed by hitler...

blend door - maybe. simple test is to have them perform a basic settings on the doors using the scan tool. it will tell them in 30 seconds if it is the door or not...

I get it now lolol...
Just got the new heater core put in ... Everything works again !
