I AM HAVING A HEAT PROBLEM WITH THE 2004 SABLE

[lonewolf5348]

The wife car seem a clicking when I turn the heater on will throw heat some time some times cold air.The heat increase dial sometimes will work other times the heat that blows stay the same even at 70 to 90 no change I can get a little better heating if I close the fresh air into the heater box.The direction on air flow to vents work up ,down,@ defroster no problems.Heater hose to heater core are hot
I here some say the baffle door other say the Blend Door Actuator
I read some were the radio removal will let you get to  the 4 bolts holding the door actuator in place ?
I read the clicking noise is a strip gear in the Actuator:other then that the car heating gauge is in the middle coolent level is o.k.
any tip or tricks will help

your diagnosis sounds about right. One trick I might suggest is to grow an extra really small hand and arm, seeing in that hole with your hand in there is tough.

This is where those inspection mirrors come in handy. Other than that, if you can't fix it with a hammer, you have an electrical problem.
