When the blend door shaft on certain Jeep vehicles breaks, the dealer repair usually requires removing the dashboard and replacing the air distribution box. This Dorman OE FIX repair kit saves hundred of dollars in parts and several hours in labor by allowing the blend door shaft to be repaired in place. This kit replaces the factory's fragile snap-on actuator arm with a redesigned screw-on arm, and includes the correct drill bit to create the proper hole to insert the new part. This repair kit is suitable for vehicles equipped with either single-zone or dual-zone climate control systems.
