Possibly faulty defroster flap actuator motor or broken wheel or link inside the heater housing, if you get to the Mercedes workshop they can easily find what's the wrong by diagnose CPU otherwise need to open dash and remove heater housing then need to open and have a look what's the wrong one by one, best way get it for diagnose by expert. is this information helped you?

What makes heater suddenly stop working but ac works fine


I am having an issue with my car !
My drain pipe for the AC is blocked again .
How do I konw because the carpet is wet near the centre hub of car under the dash.
My AC works but I noticed the heater not working due to the water sitting on top of the heater. I also noticed the demister was blowing cold and water vapour. So my demister on the front window was fogging up the windscreen .
Get a mechanic to check the AC drain pipe !

2015 carens, its either front windscreen demisting OR car heating, but I need both. How to fix?


If you set the temperature to a high temperature when demisting, it should still provide heated air, just not through the dash vents aimed at you. Is that not sufficient? Does your car has seat heaters?

Steam coming from vents


Sounds like a faulty heater core. Does it smell like rotten apples or anything like that? If so its coolant

No vacuum at air con vent control knob in vu commodore


check small vacuum hose on rear of square inlet manifold top that goes throught firewall ( bulkhead ) is not cracked or has come off
it goes into cab near heater hoses. this is the vacuum supply hose
if you have no vacuum the heater controls default to go to windscreen. also check the black & white plastic little round one way valve for leaks & operation
also check vacuum hose that goes onto heater tap that is in right inner gaurd under brake master cylinder area for leaks and that its on the heater tap valve
if they are all ok check inside do you hear any hissing noises behind dash controls or down at front centre console area?

I have to turn on the air conditioner to defrost my front window during the winter time. If I turn on the heater to defrost it gets worse. How do I fix this?


To understand how a/c works will explain what is happening. A/c works by moving the haet from inside to outside. at the evaporator which is inside the car this action freezes the coils and the hot air of the inside condenses on the coils and water is drained outside. When there is no more water left in the air in side the car the windscreen goes clear. When you use the heater the water in the air in the car will still form as fog on the inside until the air temp dries it out. In short it is more efficient to use the a/c for short spells to clear the screen than the heater demister

My demisters not fully working


That's because the heater elements in the screen have become scratched. Either from loading something sharp against them or from carrying a pet in the back.You can purchase a repair paint to touch up any broken areas. Something like this product:
