When replacing a stripped blend door actuator, and after wires connected, the actuator motor will spin 360 degrees and will not stop. When it's started with power it rotates and even sometimes with no power on the actuator. I think it might be the control panel. Tell me what you think please.

Good afternoon,

Is this with the actuator in the car or out of the car?

When it is installed, it will learn the sweep once it is commanded.

Yes and no, I removed the old one and plugged in the new one. I left the actuator loose and in my hand. It would rotate 360 degrees constantly and intermittently rotate even when power was not applied. Since I took apart the other actuator I know that it consists of only a simple motor and gear set. It has no means to stop running unless it is given a command, it does not rotate into closed and stop as it should.

This sounds like the control head as that is what controls the signal to the actuator.

You will need to replace them together or at the same time. Install the actuator before testing it. Do not test it off the door.

No signal goes to this motor. Power is the only thing it operates off of. The "signal" is merely an input demand that the driver dials in the control head coordinator give the required voltage to the motor so it can make minute motor movements. So, if you have a bad control panel and your unmounted motor spins and never stops, if you mount it with these full inputs, it strips out.

Power is the signal. When you command the door to change, a signal or power is sent to the motor to work in the direction of the command.

The 2000 HVAC is actuated by vacuum. Check under the dash for disconnected, damaged, or broken vacuum hoses. I have attached a list of where the vacuum hoses go to help. Let me know what you find.
Joe
PS: It isn't real easy to check these. They are up and under the dash. If you are lucky, with the engine running you may hear a hissing sound that would indicate a leak.

Heater problem
2004 Chevy Impala 6 cyl Front Wheel Drive Automatic

My son has 2004 Impala with a 3.4. The heater was blowing, but was only cold air. I had the thermostat replaced but it didn't solve the problem. I then realized that he had dual interior heat controls, and the passenger side was was blowing hot, with only the drivers side blowing cold. Would this 'simply' be the contriller unit with the slide bar (on this model) that controls the drivers side? I have a haynes auto repair guide, and it doesn't look terribly difficult to remove the parts of the dash to get to this unit, but I don't know how accurate that book is.
Thanks

My AC/Heat/Rear Defroster control unit worked great until the last month when it started working intermittently. It finally died 3 days ago. Now nothing works! I installed a brand new control unit today but the rear defroster/AC/Heat/Blower controls still don't work. I noticed the outside air and inside air buttons on this control unit are BOTH lit up at the same time but when you turn the dial to the front defrost only position the inside air button lights up and when you turn the control to vent or floor position the outside air button lights up. Unfortunately, I still can't get anything to work! This is a vacuum and electronic control unit. What should I look for next?
Thanks for your help,
Mike

Right heater control not allowing heat to come through on passenger side. But works fine for air. Note, this car is equipped with dual (heat/air) controls. One for drivers side, one for the passenger side, and electrically varies the heat or air through these controls for left or right side of car. I have checked, and all vaccuum motors are working. What kind of electrical problem might I have other than the right switch control itself?

Recently. Off and on. My cruise and AC panel controls will either not come on or may cut off while driving. They don't stay off but it's aggravating. I read in manual that these are controlled by same fuse. What could be causing them to do this? And how do I fix it? Other than the fuse itself. Thanks!

The divertor or blend door inside ducts is stuck or not working.

These doors blend air and divert air to vents or to bottom.

Part of dash will have to be removed to repair.

If you turn everything to max cooling the noise goes away immediately. Sometimes you can just touch the car (no ignition turned on, not sitting in the car) and the flapping starts. It will then go off in a minute or so. Help?
