No Rear Heat

[JesusArTorres]

My 03 Yukon gets no rear heat. The front works, although not fine. It blows warm. I know the engine has to get hot for the air to start blowing hot. So eventually the front starts blowing warm, but the rear blows its coldest always. Should I replace the rear actuator?

Hi Jesus, you really should do a search prior to posting since this topic is a common problem and has been talked about extensively.

Most likely, it is your rear controller. I think (not certain) that many people talk about replacing their actuators, but it is really a controller problem. The actuator is pretty darn simple device; i don't see how they can go bad, except if motor burns out.

I snooped around the forum but not much helped. You can see my posts on these.
