plasticpat Posted November 21, 2012 Share Posted November 21, 2012 How do chief :) , I had a similar problem on a '96 Fiesta Courier , in my case it turned out to be the heater control valve sticking in one position . You can find this valve under the bonnet in the bulkhead area plumbed into coolant pipes with an electrical connection to it . Somebody who knows more than I do will tell you how to go about getting it replaced . Hope this helps . Regards , Plasticpat . Quote Link to comment Share on other sites More sharing options...
