    Cabin Temp Actuators Problem?

    Hey guys,

    Both sides (driver & passenger side) of my temp actuators have not been working for a while now. Today I finally had some time to fully inspect them. The motors both work and spin nicely, but it seems that the problem lies with the motor's teeth not touching the gears of the actuator arm itself. I played around with the motor on the driver side and passenger side but it's still not gripping the actuator arm gears. The gears on both the motors and actuators are in good shape and not grinded down at all so the problem doesn't lie there.

    I removed both motors and inspected them, the long metal shaft with the metal gears attached to it seem to wiggle when moved around... both sides do this! Now is this normal?? I'm thinking this could be the cause of the gears not gripping the actuator arm gears, but since both passenger side & driver side motors do the same thing, I'm really not sure if this is normal or not. Does anyone know? or have any suggestions on how I could fix this issue?

    Thanks!

    Re: Cabin Temp Actuators Problem?

    Guys, I figured out the problem and fixed my actuators on both drivers and passenger side. Apparently the shaft on the motors for both driver side and passenger side were sticking out too much for some odd reason! I tapped it lightly with a hammer and it went back in. The shaft was not even suppose to show on the motor, only the gears, but for some reason they were sticking out! Once the shaft was back inside, It worked perfectly! This was the reason why the gears were not moving, the teeth were not even in contact due to the shaft sticking out. Just posting this in case someone else gets this issue. Hope this helps!

    I've been looking at tackling this for awhile, didn't know where to start.

    I was going to suggest to our friend who started the thread what he actually did as I read to have the shafts pushed in. I cannot find the post but from re-collection I believe you don't need to remove much to actually push the shaft in. I will try to find unless frmg0014 explains earlier than that.

    I kind of remember my mechanic kind of reach in under the glove box inside the car also once when he discovered later my Carbon Cabin Filter (located right hand side under the cowl) was blocked to get the air moving.

    Regards.

    From what I can tell from this CompNine diagram, there is only one actuator in a 97-99 heater system which is on the passenger side of the blower motor. Are you guys using the right terminology, and maybe thats why I've never been able to find a driver and passenger side?

    North America:

    Right Side= Passenger side
    Left Side= Driver Side

    Cheers.
