NHTSA ends Ford E Series HVAC investigation, no recall ordered
The National Highway Traffic Safety Administration investigation of select Ford Econoline, E350 and E450 full sized vans began in late 2009 after the federal safety authority received over a thousand complaints about the HVAC control switches getting hot – hot enough to stop working, melt and in some cases, even catch fire. A few months after opening the investigation into the switch panel in over 1.1 million Ford vans, the case was elevated to an engineering analysis. This step typically leads to a mandated recall but after more than two years of work with those switch panels, the NHTSA has not found any safety defect that requires a recall of these vehicles.
The NHTSA found that when the switches in these 1997-2008 Ford E Series vans begin to fail, they are designed in such a way that there is little chance of the melting components leading to an open flame. That leads you to wonder what exactly happened in the case of the two vehicles that did catch fire but with just two cases out of more than 1.1 million vehicles, it seems like a fairly rare issue and in the opinion of the federal government – not enough to warrant a recall. For the record, there were no injuries in those two reported fires and in the other cases where the switch melted and created smoke, the smoke wasn’t thick enough to prevent the vehicle from being driven safely.
Even though Ford Motor Company has not been ordered to recall these full sized vans, the company has taken a few steps to help prevent further issues. First off, Ford has changed the design of the HVAC blower motor switches to help make it less likely to short out, overheat and catch fire on new vehicles. Second, Ford has issued a Technical Service Bulletin (TSB) to dealerships around the country detailing how to repair this issue to prevent any problems in the future, which includes replacing the switch and the electrical connector at the same time in the event that the switches fail.
While some owners of the affected vehicles might be unhappy to hear that they won’t be getting their vans fixed for free in the future under a recall order, Ford has pointed out that these hard working full sized vans have traveled somewhere in the range of 128 billion miles and after all of that, just a thousand out of 1.1 million vehicles have experienced a problem with these switches.
