Ok Guys. I'm hoping you can help me decide what to do next.
I have Hot Air on the passengers side and only warm air on the drivers side. I've removed fuse 27 (4,5, times) no fix.
I do not have any HVAC codes. I also have a clicking noise that will increase as the fan is turned up.
All the vends will blow air as you move the controls to def etc.
So is this the Actuator problem on the driver side, or should I look for something else.

 

Guys, I'm now getting code B0441. I've tried disconnecting the battery, removing the 27 and 18 fuses. Still getting the code. So I
remove the console the knee panel and look for the Actuator. I could not see it. I live in the Raleigh NC area. Is there anyone on the site that has done this removal an lives in this area? Thanks. I sure hate to go to the dealer to get this fixed.

 

If you need pictures, let me know. This is under dash on drivers side.

Guy's just one other question. I had the manafold removed to have the oil sensor replaced.. Could... reinstalling the vacuum hose incorrectly cause the same code / symptoms as well? (code B0441) hot on one side cool on the other.

 

If you make it down to the Myrtle Beach, sc (whiteville,nc) area... i can show you how to do it. I've had mine apart several times.

 

I know this is an old thread but I have searched and this is the only one I can find that has the same problem I do.
I tried all day today to find the actuator,
I am a large guy and can not maneuver very well when lying with my back in the floor and my feet on the backrest of the seat.
I found and removed the Bose module but could not find the actuator.
does anyone have a pic or can tell me a bit better how to find it?

My problem started when I left my radio on and ran my battery down.
After charging it and starting the car I get great heat from the passenger side but the driver side stays cool. I tried the #27 fuse trick and the funny thing is the dang thing will blow hot air for about 30 seconds after replacing it.


I have found I can stay warm by turning the vent to recirculate and keeping the air blowing on the floor for a while and then turn to vents and it will blow semi warm air but the windows fog over fast.

If I can not get it fixed before it gets too cold I am going to hook up a flasher on fuse #27 so it will kick it off and on constantly. LOL That would keep me warm but would most likely be the end of my computer before the end of winter.

At the moment I am using the car as a DD and do not have access to anything else to drive.
Of anyone has pictures or ideas please post or email me at my username here @hotmail.com

thanks in advance
Jeff

 

If you get under the drivers side (I think I read where someone removed the seat and put a pillow down to lay on) , remove the kick panel, you will see a metal box with two screws, remove the screws and let it hang to get around it, and you will see the actuator behind it. Good luck. I did this this summer. Also, does the code have a C or H after it?

 

Thanks,
the code has a c
I am going out right now to try and see if I can get to it.

 

How long have you had this car? The only reason I am asking is because I had these problems (and more), went to get the actuator out and found it was missing, just the wire harness hanging loose.

 

My actuators are doing the same thing after having the drive belt slip off.

 

I have had it about 3 years.
My problem started when my battery ran dead and I had to jump it off.
I left the heat on and somehow the one actuator got out of sync.

 

after removing the seat, and most the underside of the dash I finally got to it.
I opened it up and found that the big gear was cracked. I used some super glue to hold it together a bit better till I get a replacement.
I also turned it 2 notches counter clockwise and reinstalled it.
It does now work but I think I should have moved it 3 notches because the driver side does now change temp but still does not get as hot as the passenger side.
It gets pretty warm, good enough not to know the difference if the passenger side did not get hotter.

I am not going to fool with taking it apart again to move it another notch knowing I will be installing a new one as soon as I can track one down.

I ran out of time so I will not be able to reinstall everything till tomorrow, I will have to drive the wife to work and keep her car.

Anyone know if the gears are avaiable anywhere or should I just get a whole new actuator?
Or will the cracked gear work for a while? It worked fine before and I really doubt that it just cracked at the same time I had to boost the car?

 

Not sure about the gears, you can easily get a new actuator which is not fixable as they are a one piece deal. You can get them about anywhere. Good to hear you got it figured out, if it holds I would just wait, and get a replacement for when it does stop.

 

My question is why does the actuator act up after a power failure?

 

I sent to a salvage yard today and checked out 3 different actuators and when I pulled the cover each one had the big gear broken just like mine was.
If someone could make a mold and mass produce several metal gears they could sell lots of them.

I checked and the new ones are in the $159 range for a dual climate system but found one for a normal system for $34 new.

I was going to replace mine with a new or good salvaged one but was unable to find one so I just put everything back together and hope that it works like it is for a while because it is a major pain in the @$$ to remove, especially of you are a person of large build. LOL
I did have to remove my seat in order to get under the dash enough to get at it.
After removing that Bose thing I was able to see it and get to it.
I have replaced my stereo system so I left the bose module out.
Is there a market for those things? Or if anyone needs one I will give it to them free if they pay shipping, it was working when I replaced the stereo system. If not I am going to trash it, i was never a bose fan to begin with

 

I think its a pretty common problem in actuators from what I have seen on here, and over priced.The Bose amp I see all over Ebay, and not too expensive. If you haven't sold your system you could just add it on if you ever did.

 

I am trying to remove the driver's side actuator today also. I am not having any luck finding it either. I have the bottom part of the dash apart. I am not that big so I am able to squeeze in there ok without removing the seat. A picture would be so helpful. Thanks!

Try this, after you remove the bottom of dash, there is a metal box (stereo amp stuff) with two screws (or nuts), remove that and let it hang, the actuator is behind it and just above it, looking up into the box area.Its a tight fit to get to, but do-able.

 

I finally found it. The bottom kick panel needs to be removed. I have removed one of the screws from the actuator. The rear is going to be tough. I need to take a break as I am getting noxious from hanging upside down trying to get the last screw. Haha.

 

Thanks dmarkshark for the help. I cannot get the last screw. I think I don't have the right tools to access. This is definitely way more difficult than I had expected. Calling it quits tonight and waiting for my mechanic buddy to come by tomorrow. Going to take the seat out to be more comfortable. Hopefully I will be able to put everything back together.
