2001 156 Alfa T Spark heater problems

Cannot get any air through the windscreen vents.Air will come through the dashboard vents but when you use the rotary switch to change the flow nothing happens, fan speed works fine, hot air takes an age to come on i assume this is only heat from the engine?

Sounds like the flaps on the heater box are not moving. you will need to check the cables to see if they have come off or if they are seized.
The heat problem could be a blockage in the heater matrix. Try flushing the matrix out with a hose from the engine compartment side.
Note: you will need to bleed the system of air after doing this.

Why does my kia picanto 2013 windscreen totally mist up and will only clear when i put ac on hwen it clears i turn ac off then within seconds it mists up again


the windscreen fog is from humid air coming in from the outside
air conditioners work by removing the humidity from the air so if you close of the outside vent then the recirculated air inside the cabin eventually has all the moisture removed
that is why the windscreen clears because there is no moist air to condense on the cold windscreen
now you will say that it is too cold and that is why you turn it off
well try this -- leave the ac on and adjust the heater control to produce lukewarm air no fogging up and not cold
it is called climate control

Air vent schematic


air for the inside of the car comes from the vent at the base of the windscreen or is recirculated inside the car
if you see what appears to be mist, fog or smoke from the ac vents ,it is extra cold air from the ac system that is seen as fog when it hits the air in the car
you will know exhaust fumes by the smell

Heat does not blow onto windscreen but blows through other vents - whats wrong


What make an model an year vehicle do you have ? The air blows out of the floor vents an center vents but not defrost ? Possible mode actuator , stuck mode door ! There is a door inside the heater / A/C assembly that directs the air to the desired position . These doors can be moved by a vacuum operated actuator or an electric motor . Sometimes thing's put on the dash end up inside the heater box , fall through defroster vent ! Pens , pencils etc.. Depends on the make vehicle an system , manual , or automatic climate control . Some of the newer vehicles the HVAC system as it is called , the control panel is a electronic control module an can store DTC'S - diagnostic trouble codes !

Hello, I have no air flow from the dashboard vents on mt 1997 GMC Savana van. The A/C and heater work fine but I only have airflow to the rear, floor, and windscreen


The first thing I would check is the blend door actuator. This is located under the dashboard towards the center, move the controls while looking underneath so that you can locate it. Once you locate it call the dealer for the replacement part before you take this one out.

A/c does not blow strong through VENTS- but only under dash floor


There are controls on dash to select position of air you want to, like front only, windscreen, below dash etc, check those. If still there is problem you need to remove the dashboard and most probably the flap which redirect air has got its cable snapped. Another possibility is the air hose inside dash are loose.

Windscreen wipers only work on fast not onnormal or int


Hi most likely the switch that operates the wipers is broke and not the wipers motor.

Get it tested before replacing it, but most often alfa's have so many electrical problems it's difficult to say.

Vent in centre of windscreen not working i have a A4 1.8T 2002 the vent in the centre of the windscreen stopped working a week ago drove the car the next day was working perfect it has just stopped working...


There is only one door. Air flows through the AC evaporator and the blend door diverts some or all of the flow through the heater core. For heat, the compressor is off under electric control and the non-refrigerated air is diverted through the heater core. The door is on a vertical axis and can swing to any position based on random corner turns, fan speed, mode, etc.
