Heater blowing Cold Air!!!

[bad-vw-boy 0]

Got in my car this morning and found that my heater has stopped working, the fan works but just blows cold air..... what is the best things to check before i have to start considering the heater matrix is knackered.....and how easy is it to replace...is there a how to section on this?

there's no valve in the matrix itself so it could be a couple of things.

1 no water in the matrix, i.e. air, the water is down on level for some reason

2 blocked flow through or to the matrix, could be faulty by-pass valves from the recall work

 

feel the hoses to and from the matrix at the bulkhead, that'll give you a clue

Check for wet carpets in the footwells too. :(

Also a clue to matrix problems :(

Here is a link to the latest how to fix it :)

or it could just be that the heat selector isn't working (the cable has come off/snapped etc.)

Deffo check all the cables first!!

Okay checked the cable and seems to be connected to the selector in the cabin controls, i ran the engine and the pipes seem to get hot, they seem a little soft and could prob abably do with replacing......just a question where does the cable at the back of the cabin controls got to ???? :brickwall:

to the flaps that direct the flow of air, you can see them if you remove the passenger side under dash tray and look up behind the centre console.
