HVAC Switch FailuresClosed
This investigation was opened based on one complaint and reports from four transportation fleets alleging 182 blower motor control switch failures.ODI was concerned that these melting and burning switches could lead to an open flame that could spread throughout the vehicle.After a comprehensive review of all data related to overheating blower motor control switches in the subject vehicles, ODI did not identify the existence of a safety defect trend.ODI reviewed 1,036 complaints, claims, and field reports of failed blower motor control switches and determined that only two fires were likely to have been caused by a failing subject blower motor control switch.This represents a failure rate of 0.2 R/100K on a population of 1,076,975 vehicles that have been in service for up to 14 years.ODI has found that when the subject switches do fail and begin to melt, they are constructed in a manner…

ODI has received 1 complaint and reports from 4 transportation fleets alleging 182 switch failures.Each fleet operates mini buses built on a Ford E350 or E450 cutaway chassis.The OEM HVAC blower switches have melted, smoked, burned or experienced open flame and become inoperable on vehicles in each fleet.Some drivers have reported a burning smell or smoke coming from the dash.One fleet reported a vehicle fire.No injuries were sustained.However, the bus was carrying special needs children when the driver noticed smoke coming from the dash.The driver was able to evacuate the children prior to the vehicle becoming engulfed in flames.This PE has been upgraded to an Engineering Analysis (EA) to determine if the blower motor switch failures create a situation where a vehicle fire is possible and presents a safety risk to the driver and other passengers.

THIS INVESTIGATION WAS OPENED ON CERTAIN FORD PICKUP TRUCKS AND VANS TO EVALUATE THE EFFECTS OF A VALVE STEM EJECTION (WITH RAPID AIR LOSS) AND A SLOW LEAKING VALVE STEM ON VEHICLE HANDING.DURING THE INVESTIGATION, ODI EVALUATED OVER 1,100 COMPLAINTS AND WARRANTY CLAIMS, CONDUCTED VEHICLE DYNAMIC TESTING ON A SUBJECT VEHICLE WITH THE FAILURE MODE REPLICATED, INTERVIEWED OWNERS, AND EXAMINED COMPLAINT VEHICLES IN THE FIELD.THE RESULTS OF THE TEST PROGRAM INDICATES THE EFFECT OF A VALVE STEM EJECTION ON THESE VEHICLES IS EASILY CONTROLLED. FURTHER, WITH A POPULATION OF ALMOST 900,000 VEHICLES, HAVING TWO TO FOUR YEARS OF EXPOSURE, ODI IS AWARE OF ONLY 3 MINOR CRASHES AND IS UNAWARE OF ANY INJURIES.THE SMALL NUMBER OF CRASHES RELATIVE TO THE LARGE POPULATION OF VEHICLES IS CONSISTENT WITH THE TESTING WHICH WAS PERFORMED. THEREFORE, THIS INVESTIGATION IS CLOSED.SEE THE ATTACHED REPORT FOR…
