01 tahoe front heat sucks

[RachelJWalker]

I took some time and looked on youtube and found these videos. I also saw another video that had no heat in the rear in that video I saw there was an actuator back there I have no idea but maybe you can take it off and put it up front just to see if it gets you front heat just an idea.

Well still no heat the back heat works great I took the actuator off and it moves and the rod it attaches to moves freely and I tried moving it with it running and heat on warmed up to see if the heat would come on and it didn't bout to be ill with the no heat especially with this cold cold weather.

I had a similar issue last winter (mine only has front heat). I had to flush the heater core, run some clog cleaner chemical for a day (got it at the parts store), and back flush the system twice with a garden hose and compressed air to get it working. Local shop wanted $100-$200 to do the same thing.

I replaced the other plastic fitting since it started leaking so I back flushed the heater core an pulled the hvac fuse out and let it clear everything. Now the heat cuts in and out and I can hear the actuator going back and forth. Does this sound like a bad actuator?

I took the actuator off and now the heat doesn't cut in and out and it stays hot. Guess the actuator was one of the problems
