Can anyone help??My heater is blowing cold air only!! I've had a new grp A head gasket fitted so I know it aint that.It isnt going through water and its still as fresh as the day it got changed.

I havent checked the thermostat as of yet.
I did notice that there is 2red wires hanging down at the passenger side foot well dont know if they are maybe out of the heater box???

is there anyway of checking that it still works?
Anyone with any info about the heater set up or any info at all that mite help then please get in touch.

cheers.
