I had the same problem around christmas time. The thermostat is bad. I wont allow the engine to get up to operating temperture. It is located under the alternator and took me about an hour and a half to change. It isnt a simple replace as in the older vechicles. It is a housing unit with thermostat built in. Hope this helps

The radiator cooling fan is always on ?


Is your AC on (AC compressor activated)? Try switching that off and see if it still runs.

A/C blows hot air intermittently


this is clear that your aux fan cooling your condensor is not working ,your a/c system is overheating and with speed you are forcing air through your condensor doing the job of the fan.

Blows cool air from air conditioner and engine runs hot


Do both fans on the inside of the radiator turn on when you have the AC on? It could be that the fan connectors were disconnected. you'll find them tucked away on the side of the radiator.
Is it always just cool air or does it get cold when you are driving? if it's always just cool and never really gets cold then you have either lost your freon or you're AC is not pumping freon. unfortunately you have to take it to an AC specialist to solve that and it's not usually cheap.

Vw cooling fan problem?


There is a relay located near the top or side of rad saddle or fan shroud, trace the wiring harness from the fans to this relay sounds like the relay is fused together or shorted out, or as simple as checking your temperature control setting inside, if you have a/c and have the fan set to any position other than off, and the hot/cold dial is in the blue those fans will always be running when engine is. Easy to check this, just have the car running and turn off your fan or turn your temp selector to max hot. If the fan still runs even when the engine is cold then revert to my first check on the fan relay.

Air conditioning seems always on


you have a bad a|c switch and far as gas consumption goes the answer is yes, because if the a|c is always on then there is a constant load on the engine
