Hi rob1960, This may not be relevant to your problem, but I had same problem with car heater fan, turned out that the motor had three coils that altered the speed, and two of them were burnt out, you could have some kind of faulty thermostate or sensor that dose simmilar type of job, there will be others along shortly with the knowlege of your problem and how to rectify it.
------------- If everything runs smoothly then I must have done something wrong
