SteveM Posted May 4, 2011 Posted May 4, 2011 anyone have any ideas what would cause the heater to occasionally blow cool air when set on warm?... have the heat set at a constant lets say 25 and now and again it starts to blow cool.. if i wind up the temp it blows hot again so i am guessing its electical rather than an actual cooling problem? no other symptoms and not causing any probs and with a nice hot summer on the way i dont suppose i will really need much heat but in the dying light of a sat eve with the roof down and a chill decending a bit of warm air is very welcome! 2007 facelift roadster if it helps Quote
Darren-B Posted May 4, 2011 Posted May 4, 2011 I have a similar problem, when on auto it will randomly put the fans on really high for a few seconds, then return to normal, ( no temperature change though ) Quote
Darren-B Posted May 4, 2011 Posted May 4, 2011 I'm thinking mine could be a dodgy temp sensor? But where is it? Anyone know? Quote
mc Posted May 4, 2011 Posted May 4, 2011 I have a similar problem, when on auto it will randomly put the fans on really high for a few seconds, then return to normal, ( no temperature change though ) mine did the same with the fan speed, I replaced the controls and it works ok now. Quote

Oh really, maybe someone will be nice enough to let me try theirs in Wales, I don`t really want to go and spend out on new controls if thats not where the problem lies, have just spent £400+ on the other car fault finding to discover the problem was a £4.38 Bolt Quote
mc Posted May 4, 2011 Posted May 4, 2011 Thinking about it now, i actually replaced both the control dials and the white box that they plug in to. I did them both at the same time cos i was in a rush, so not sure which was the cause of the problem. Might be a similar issue for the OP ? Quote
Darren-B Posted May 4, 2011 Posted May 4, 2011 Yes quite possibly, Sorry for crashing the thread Quote
