Heater woes.

[tobyd]

Hi all,

Can anyone help desipher what is wrong with my 500E's heater.

The heater only ever blows hot (not warm) air into the cabin until the temp selector is set to minimum and then we can get aircon cold air.

The other symptom is while the engine turns over at less than 1500rpm or while idling at lights, the warm air stops after a few seconds and then cool air until i get moving or rev the engine, then warm air arrives again.

This is a pain at this time of year so I'd be grateful to anyone who wishes to share their knowledge with me.

Many thanks



Toby.

coolant levels ok? coolant pipes blocked with mayonnaise = matrix blocked with mayo. Also check for wierd scuffling noises from the centre blower; which I think are caused by coolant scrabbling to get through the matrix.

Could be a harbinger of doom (whatever that is) but check this because mine was doing exactly the same thing.

All flushed with Persil automaitc now so hot in cabin, but I have a horrible feeling the coolant system is getting pressurised which means the head gasket is blowing which means hideous expense.

weep.
