Mk 1 heater only works on recirculate?

Nov 06, 2007 13 Replies

Can anyone help with the above please? I have a (new to me) 1995 Uk spec model. Very happy with it so far. The weather's still relatively good here, still above freezing, but I've noticed that the heater doesn't really work when the air setting is on fresh air. If I move it to recirculate, then the heater works really well. Is this normal? I've googled but can only find articles relating to the heater being continuously on.



TIA


The control levers for the heater are located behind the glovebox. Remove the glovebox and you can get at them for repairs or adjustments.

The hot water is always flowing through the heater core. The temperature control on the dash controls the mix of unheated air from outside with the air that is heated by the core. Maybe the temperature control cable has become disconnected, damaged, or the door or operating lever is not working.

Good luck.............

Please describe in detail what you mean by "doesn't really work." It works a little? Cold air comes out? No air comes out? Purple lizards come out? With or without the fan?

Why would purple lizards try to steal a fan??

For their fan dance, of course.

Is the fan dance performed *with* the fans, or *for* them?

I think he's confusing the purple lizards with their blue cousins.

Ours is performed under them.

Ah... so the fan has to be lapped.

Lap dancing with a fan? Sounds risky...

On older cars the foam rubber round the heater can crumble away, allowing cold fresh air to bypass it. This is apparently fixable without ripping out the dash:

Bingo. Thanks for that. The foam wasn't crumbled away, but the pipe between the fan and the heater matrix wasn't connected properly at either end.
