DETROIT (AP) - General Motors and Isuzu are recalling more than 249,000 SUVs because the window and door lock switches can cause fires.

The recall covers the Chevrolet TrailBlazer, GMC Envoy, Buick Rainier, Isuzu Ascender and Saab 97-X SUVs from the 2006 and 2007 model years. The SUVs were sold or registered in 20 states and Washington, D.C., where salt and other chemicals are used to clear roads in the winter.

GM says fluid can get inside the driver's door, causing a circuit board to short. The short can knock out switches for the power door and windows, causing fires. GM says there have been fires but it doesn't know of any injuries.

Dealers will replace the power widow switch for free. Owners will get letters telling them when to schedule appointments.
