If your thermostat is stuck open then it's quite possible on a cold night that the radiator would still be fairly cold. Thermostat should only allow the water through the radiator once the coolant is at 85C. If it's allowing it to circulate when cold then it will take ages to warm up.
 
... Its definitely nowhere to be seen

Looks like the 'small' 'bump' that I had in the car before has absolutely trashed that side and the air temp sensor is nowhere to be seen, neither is the wiring.
Does anyone know where I could trace it back to? What is connected just before it, or at all etc?
Any help would be appreciated!
