Owners of select 2019 Ford Rangers will have to take their rides to the dealer again to address an issue that should have been solved last October.

Back then, the automaker replaced the heating, ventilation and air conditioning (HVAC) blower motor, as part of the 12S34 reference number recall. However, as it turns out, the technicians used defective parts during the repair, and now the same batch of cars is being called back again.

In a short press release issued earlier this week, Ford said that “the replacement part used for that service may have been built with an improper clearance between an electrical terminal and the conductive base-plate slot”.  What that means is it does not meet the legal safety standards, as there is a risk of the blower motor either overheating, melting, smoking or causing a fire.

The electrical short is estimated to affect only 4 percent of the 5,384 units included in this new safety campaign in the United States and federalized territories and 418 in Canada. All of them were assembled at Michigan from August 1 to September 27, 2019.

Ford is unaware of any accidents or injuries related to this condition and has already started informing dealers. Owners of the affected Ranger pickup trucks should hear from the company between April 6 and 10. Those who have fixed their vehicles on their expense will not be reimbursed, as it would have been covered by the original warranty. The reference number for this recall is 20S12.
