Not strictly a 1.5 yet, but my LHD Mk1 will not emit warm air from the fans.

Whilst this is not important during the day down here, it can get mighty cold at night.

Can anyone point me in the right direction before I start taking things apart that don't need to be.

The engine cooling system is fine as I have just had the head gasket done.

I have had a look at the Haynes manual but it is not very helpful other than telling me where the heater relay is. (Which I will be checking this afternoon).
