It is possible that the engine block temp sensor that is on top of your thermostat housing is faulty and not allowing the fan to blow.


The senor is located on the top of the thermostat housing. Next to it is a temp sensor to activate or allow vacuum to the egr valve. This sensor has a thin wire going to it not vacuum hose.

To check it remove the wire from the sensor and ground it to the body of the car.... just use a loose wire to ground it. and IF the climate controls work then thats your problem.

Now if that is the problem you can temp fix it by grounding that wire to the body. but I would suggest getting the sensor replaced as cold are on the feet is no fun. also you dont want the fan going when your trying glow plug
