SOURCE: 2000 Astro van - vent

The problem is a 1/8 diameter hose that runs from the front of the engine over the top and connects at the rear of engine on the drivers side. It is a vacuum hose #GM15967970 It cost about $6.22 at your GM dealer. Hope this helps Bill. My E-Mail is Uflyups@aol.com
This was posted on a problem with a 2002 astro, I do believe it is the same fix. A simple vacuum hose, It is difficult to route through the engine

SOURCE: Vent Acuator on 1994 Chevy Silverado

I had the same problem and changed it myself. It was a job but can be done yourself. Some call it a Recirculation door actuator, some call it a blend air door actuator. If you look under the dash behind the glove box all the to the fire wall you can see it.There is 2 screws 1-top 1- bottom which you can see easily, the top one you cant see from bottom you have to take out the glove box to see. There is a plug that goes to the actuator, you can actually just unplug it to stop the noise, that will fix the noise and I know some people dont replace the actuator they just leave it like that. I had to go buy a air socket wrench to replace, the smallest one I can find. I wouldnt have done the job without it. Good luck hope this helps. Steve

SOURCE: Blend door not working.

The bleed door controls air temp not where it comes out, dash, floor, defroster, this is most likely a mode control switch problem, that switch is on the ac control head.

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.

I have a 2004 Silverado HD with dual climate control. The vents for the floor and defrost work fine but only one dash vent(drivers side next to radio) blow any air out. Any suggestions are greatly...


There is an actuator located at the bottom of the dash .. just remove it and turn that little shaft with a pair of pliers gently one direction or the other and see if that's the problem if so replace that actuator,, ((((((( be shure to unplug the actuator before starting the truck )))) and disconnect your battery when u install the new actuator .... so the climate control can relearn its position for accurate door travel...

2004 chevrolet silverado ac is not blowing through dash vents only through defrost vents


these trucks are equipped with an electric vent door motor known as a vent actuator. I believe the actuator that controls this vent is located behind the dash on the driver side.

My 2005 2500 HD Duramax is not getting any heat inside cab. Engine is not running hot and coolant level is fine. Turned the heater controls up and down fast today and ot some heat for a while.


The temperature of the air coming out of the ducts is controlled by a door that moves between the heater core and the AC core, it is called the "blend" door for obvious reasons as it blends the hot and cold air streams to give the desired air temperature at the dash vents. The door is controlled by a small gear drive DC motor called the blend door actuator, what happens in most case is the actuator is damaged by a blend door that is warped from heat being hard to move or not moving at all which is the case with your truck. The blend door and its actuator should be replaced as one repair, the dash must be removed from the truck to access the air ducting that contains the blend door, you absolutely need a service manual to complete this job, it takes about 10 hours.

Heat/air blowing through the vents


The actuator may not be the problem you may want to lean more towards your hvac control unit

Heating system only blows out hot air through the vents


I would look at the air blend doors first, it sound like they are not working or your control in the dash is not working send a signal to them. they work by changing the air from hot to cold or in between.

I had this problem in my pontiac grand prix. it was the dual zone door actuator.( I can't remember if that was the technical name) basically there is a door underneath and behind the dash, depending on how much cold or hot air you want there is an actuator that opens or closes the door.
