The driver’s side master power window switch is prompting a National Highway Traffic and Safety Administration investigation on 2006-2007 Chevrolet Trailblazer SUVs. The NHTSA noted a similar issue with Toyota RAV4s last week.
So far, the NHTSA has received 12 consumer complaints on 2006-2007 Trailblazers about melting or burning of the driver’s side power window switch. Many of the complaints say the problem led to burning plastic door panels, fires occurring while the vehicle was in operation, or when the vehicle was unattended.
It’s unclear whether 2006-2007 GMC Envoys will eventually be included in this investigation, but NHTSA has also received similar complaints for GMC Envoy owners from the same model years. It is also not yet known if the Saab 9-7X and the Buick Rainier could also be affected.
