Hi all,

my internal fan heater has a problem. The fan blows cold air when idle or is driven below 1500 rpm.....when I am driving at anything above 1500rpm the fan blows out hot air.

any ideas about which compinent could be faulty would be greatly appreciated.

Many thanks in advance

Hurley.

Thanks Neal.... I don;t have the ability to jack it up onto ramps, but I think from reading the whole thread it;s the valve, as it does heat up to a normal temp when being driven, and I have no engine temp issues as the gauge never goes past half way. I will look at the valve and report back.

thanks for the instant reply...... brilliant. :D
