radiator fans
« on: 06 March 2008, 13:05:36 »
hawing problems with radiator fan (it wont turn off even when i turn the car of only thing is to pull out 30A fuse) and climate fans are also on even that climate is off, but they switch off when i shut down the car). I checked the relays today but no success. Do you have any ideas on how to solve this problem cause this is pain in the ass my car cant get to the normal temp with fans always on.

It should make no difference to the oeprating temp as this is controlled by the thermostat.

Which fans are you referring to, the ones on the aircon rad or the main one in the engine bay?

91 is about the optimum operating temp.....any higher and the fans kick in to cool it, any colder and the thermostat shuts.

Remember also that the two fans at the front will always run with the aircon turned on

Sorry, just trying to get it straight in my head exactly what the operation you are seeing is.

ok lets go again.
aircond switched off car cold.
fans of the radiator are always on even if i pull key out of ignition.
fans of the aircond switches on instant when i put the ignition key and turn it ( air con is svitched off)
only thing for me is to pull 30A fuse out if i dont pull it fans run thill my battery is dead
