Finally got the chance to escape in the van,even if it is probably the coldest weekend for a while.I have a problem though with the trims heater ie fire.When set to a low setting ie 1,2 or 3,it only stays lit for a very short time before it starts clicking and trying to reignite.On the very highest setting it stays on ok but feel as though we may be stripped to our underwear before long,and nobody wants that!Any quick fix ideas please?It is still under warranty but would like to turn it down before I fall asleep
