Half working Heater

Forum: 

Hi All,

Please could I ask for some advice I got a Fourtrak TDS (91). I think I've got a problem with my heater. Heat only comes out of the bottom vents and I only get cold air from the top.
I'm guessing that this isn't normal and hot air should come though all vents. Is there something I could check, or does it mean my heater matrix is on its way out?

Thanks,
Phil

heater problems

maybe one of the little cables that operate the flaps that direct hot or cold air up or down has come off. Try moving the up/down lever whilst looking at the various linkages in the drivers footwell, do they move Unknw My hot / cold cable came off its clip just behind the controls because it was so stiff. You could move the knob but nothing happened.

normal...

Hi Phil.
This is normal, and is the same on many cars, mainly older UK ones too (that I've worked on anyway...original mini's and my dads Mk2 Cortina for example. No clue why.

It should blow hot or cold on your feet and windscreen, cold through the centre vents.

try this, my heater matrix

try this, my heater matrix has a hole so I disconnected the pipes to it, so now I just get permanent cold air coming out so I dont have an issue of mixed heat BiggrinBiggrin :-D, lol, its fourtrak characteristics im afraid, go on a loooong journey towing and it'll work fine. :-D, unless as stated a cable came off, also check the water level in the rad.

Full of ideas but no time to do them!!
