'97 Ford Explorer, No Heat

Q: I just replaced the thermostat and a broken potentiometer in my ’97 Ford Explorer. It still does not blow any hot air. How do I go about replacing the heater box or blend door I read about in your article? Is the heater box/blend door a dealer only item?

- David

A: The heater box is a dealer item only. Ford has had a problem with these heater boxes. When you get the replacement, make sure it is the latest and greatest. Why? Ford has updated them more than once due to problems. As for telling you how to replace the heater box? There is not enough room in this column to walk you through that job. If you’re going to be performing your own repair may I suggest the ALLDATA DIY program. To replace the heater box in your vehicle is not a simple job. You will need information and diagrams to do the job right and not lose all your hair in the process. I’m not saying you have to have this product to do the job. But, I will tell you I would not approach a job/repair of that type without the information provided in the ALLDATA System. So before you tackle this job, go online. Information is going to be the best tool for you to purchase in repairing your vehicle.
