How many blend door motors does a chevy impala have?

I turned on the air conditioner and when i turned it off it started making a clicking sound in the dash. I have had this replaced twice and was wondering how many more I will have to replace? Very frustrating.

If it will not switch to any different positions,and you did not have this problem prior to repair.Check for a leaking vacuum line to the control unit.The line should run through the firewall to the control unit.Good Luck!!!

SOURCE: 1995 Chevy k1500 heater problems.

For a 95 Chevy Silverado....I replaced the Blend Door Actuator on the passenger side. Just behind the slide out cup holder. Yo ucan acces easily by removing the ash tray piece and the glove box....Or just the glove box and work like hell to get a socket in a tight place.

There are 2 actuators....one controlling the (Mode and Temp 89018681) and the other the (Air Inlet 89018367). I called the dealer and the parts were 85-125. I got it From TBA Auto (local store) for 39.00. A 20 min job at most.

SOURCE: Air conditioner blows hot air after 30 seconds on

I have had this problem. I am not a mechanic...so to correct the issue temporarily, I simply turn off the car and restart. This has worked everytime for me. In extreme cases, I think you can also remove the AC fuse and start the car, which will also reset the computer. I also think that by taking the climate control off the "AUTO" setting has worked in the past.

My 2006 Impala has an intermittent loud clicking sound coming from under the dash. It will happen with or without the car running. I am also having trouble keeping charge on my battery.


This is probably the Air Blend Door Actuator. There is a small gear driven motor that opens and closes the various heating and air conditioning vent doors inside the dash. Since you hear it after turning the car off, it is most likely the fresh/recirculating air door, and they are designed to automatically open to allow fresh air in when the car is turned off. The clicking you hear is the sound of the gears slipping inside the actuator. The parts are fairly cheap ($20-$35) and with simple hand tools can be replaced.
Here is a video showing them replacing one on a Monte Carlo, which is basically the same as the Impala:

No matter what setting you have the air or heat on, it still comes out all the settings(vents, defrost and floor vents) all blow at same time in my 2003 chevy impala


sounds like you have a bad blend door motor that is stuck in the middle allowing for all vents to blow air... locate the motor under the dash and remove it. manually move the lever and see if it changes the flow.. check for power at that motor to make sure your getting the signal from the dash then you'll have found your problem....

Clicking noise under dash near blend door. Removed fan and clicking still there. Is it possible the blend door is causing the clicking. It only starts when temp controls are moved from col to warm.


could be the blend door actuator(motor) when its clicking, disconnect it, if it stops then the motor is bad. If you want to.....if you mostly have it on recirc anyhow, just disconnect it when the door is open.

Seems to me that you may be having an issue with your climate control blend door. It maybe getting stuck with something in its way or you may have a bad blend door actuator.

2006 impala heater motor blows like normal but some mornings it blows cold if we shut it off and turn it on a couple of times it will blow hot and work fine. the heat gauge is at half way when the engine...


this problem is caused by a sticking air temperature control blend door actuator or blend door, this door moves back and forth to get the desired temp, the actuator is electronic and prone to this type of problem, suggest u replace it.

Air conditioner problem 2001 Dodge Pickup


Hello, It sounds like your hot/cold blend door actuator is either hanging up at times or it's loosing it's calibration range because it's starting to go bad. The ticking noise is most likely the actuator trying to close off the hot air port but is unable to stay closed allowing hot air to mix with the cold. If it's just a weak blend door actuator, it will act up more when the air is on full because it has more resistance due to air flow. If possible try to see if the times it acts up decreases when you start the A/C with low fan speed.

The problem is in the heater box. To be more specific, the blend door. Check blend door operation and blend door motor. Located right side under dash. Remove blend door motor, with vehicle running, move switch from panel to defog and see if blend door motor moves.
