Heater problems

[brokencars]

This is my first Tundra . It is a 2009 4 dr . The problem I have is with the blend door. Have had all the other brands and know what to fix. Read some where there is like 3 blend doors. A little advice would be help full . Thanks

Have you checked to see if the actuator motor/servos is operating when you turn the heat knob temperature control knob (reostat) ? Usually is the actuator is not working (either bad actuator or reostat in dashboard controller). Access is easy from either foot well for each side unit. If the blend door/s get stuck or froze the shaft that feeds them are plastic and may sheer off so if actuator motor & arm works, see if the shaft is turning. Hope that helps.
