radiator fan running high
Is the engine hot? If so the fan is doing its job.
no, the temperature is normal
The fans should come on at preset temperature and then cycle off once the fans cool things down a bit. Are the fans coming on and off or do they stay on all the time?
only 50,000 miles on it. also the heater is blowing cold air.
the fan gets loud after about 15 minutes of driving. it has never done this before.
If you have a clutch fan the clutch is probably bad. The heater problem may be a bad thermostat or air in the system.
both symtoms seemed to be linked because they began at the same time.
If the engine is running hot the fan will come on more. Maybe you should service the cooling system.
Is the fan electric? If so it could be a defective pressure switch on the AC compressor.
