    My heater works but air only comes out of the main vent in front of dash,turning control knob has no effect.

    First my partner removed the switch panel and found a broken part so that the air couldnt be diverted up. He fixed it with wire. Then he found a leak into the passenger footwell so water wasnt getting to the heat exchanger and there wasnt much heat. Radweld sorted that out. Now everything works!

    • i have the same problem with the heater the only thing to do is to move the plastic bracket where all of the cables are located in the footwell until you can find out which cable has either broken or streched the plastic bracket can be very stiff but a good sokeing of wd 40 useualy puts it right

Look underneath the drivers foot well and you will see that something has snaped on the cable put your hand underneath and push it upwards you will have to leave it like that for a bit because i have just found the same thing and dont know how to fix it yet

SOURCE: heater only blows cold air but hoses are hot

It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
If persistent boil ups/over attention must made in the cylinder head
or gasket area, or possibly water pump?

Make sure the heater core is in the open position by using the shut off valve and turning it to open. next, you may have a malfunction in the direction door the directs the air flow in the dash. a lever may have become lose or separated. may be a bad servo motor not directing the door to move to the heater position. i would start by checking that shut off valve first on the heater core.

Windscreen not being cleared by heater

Modern heater cores are very fine. They will act like a strainer. Have the heater core flushed out. You will be amazed! Just take the heater core hoses off, take compressed air, blow through the heater core both ways while adding some hot water once in a while. This will remove the debris from the heater core. Now, hook the hoses back up and fill your coolant system with the proper coolant. You will be very happy with the results.

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 !

My car does not blow hot air through the vents. On the windscreen its okay. The air coming is smelly. What could be the problem. The car is 1998 model

if it smells sickly sweet and there is a fine mist you most likely are leaking coolant into the heaterbox. generally this means a leaking heater core.

I have a 1998 Honda civic 1.4i.Turned car on this morning heater on full to defrost windscreen.After 10 minutes still blowing cold air!No noises etc and all settings work but still cold air.Help!

Are the radiator hoses from the engine to the firewall hot? If so, it's probably not the thermostat, it's probably either the heater core or the controls not allowing the heat to get in. Best advice I have (because I had to replace the heater core in my car last year) is to buy a Chilton repair manual for it. it walks you through everything. If it is a heater core, be prepared for a long job...

Hot air not blowing on windscreen.

The switch was broken that diverts the air to the screen vent and we accessed it via the switch panel. Clever partner wired up the broken bit.
