Chrysler has issued a recall for 37,407 2009 Dodge Ram 1500 pickup trucks equipped with manual temperature controls. The software for the heating ventilation and air conditioning module may not work, causing the windshield defrosting and defogging functions to fail. This could become dangerous if visibility becomes impaired while driving.
Dealers will reprogram the module for free. Owners may contact Chrysler at 800-853-1403 or the NHTSA Vehicle Safety Hotline at 888-327-4236.
