Alright guys looking for help with my heaters. All they do is blow cold air all the time. The viscous fan is removed and there an alloy rad with twin electrics fans running constantly.

The guy i got it off said if i disconnected 1 of the fans that i would have hot air but i dont know??

Anyone have any advise for me because i nearly died last night driving it home in -3 degrees. Haha.
