I had these two codes come up in my 2003 Z06 several times B0361 and B0441 Left Actuator Feedback Short to GND and Left Actuator Out of Range. So a local Corvette shop replaced the left blend door actuator. But I still get the same two codes, but here's the funny part, both the air conditioning and heating are working fine and all the vents are operating normally. So why or what is causing this to happen.

Thanks in advance
Pete

 

Can't believe no one is helping a veteran! I wish I could.

 

Well maybe someone might come along and know the answer to this will see...... Thanks egrand333

Did you clear the codes after the actuator replacement? Are you sure they replaced it and just not charged you for doing it?

 

Do these codes come back as H or C codes?

 

I watched them replaced the actuator and cleared the codes. (I have the old actuator) And I personally have cleared the codes many times. they come back as C codes.

Pete

 

If you open the old actuator, you'll probably find a cracked gear which is the common failure for this. The actuator they put in, was it new? I'm not sure what else to suggest without taking it to a dealer to use a tech2 on it.

 

This is just random, but disconnect the battery for a short period, let it reset. I know when I replaced my drivers side actuator, it came back as a C code sometimes, or an H? . It finally just stopped coming back, and I haven't seen it since. I don't know, just randomness? There is also a fuse you can pull under the passenger side floor panel, which will reset the actuator. I don't remember which one exactly , but is marked under the fuse panel cover (HVAC). Try both and see what happens.

 

Ok, I'll try the Battery and the Fuse hope It help's
Thanks for everyone's help, I'll let you know what happens.

Pete

 

Update: Sorry it took so long to get back to you, I disconnected the battery for about 6 hours and still the codes come back. I also cleared the codes while the engine was running. Any other thoughts?

Thanks
Pete

 

Pete, I had the basically the same situation in my 2003 Coupe. You did not indicate whether you had the repair done because of improper HVAC operation or just because the codes came up and you wanted them gone.

My unit(damn those useless dual-zone systems!) was working all right but threw the same codes. So actuators can be unbroken but still throw the codes if out of "sync". There are apparently several ways to force the actuators to re-index properly and then the codes can be cleared. I eventually cleared mine and they have not returned yet after some additional mileage; system still seems to work properly.

I've tried to find the rather long post on repairing/reindexing actuators but searching the Forum is not giving me the post I saw some months ago and used. I'll keep looking and get back here if I find it. I do remember that the Forum's "Yoda", Bill Curlee, posted some of the info I used. My "fix" involved manipulating the system's controls in various ways, engine running and not, but I can't remember exactly what I did.

Did you check your removed actuator to see if it was one of the ones that broke its gear? If not, it may be a perfectly good piece . If yours does have a broken gear, don't toss it--you probably have already seen that recent post about someone who epoxied (sp?) their broken-gear actuator and returned it to service.

 

First off,, THANKS FOR SERVING!

Try this

Set the temp selector control **** to the center of the temp range. Turn the HVAC OFF. Reset the DTCs in the DIC. When you reset them, you should hear the actuators CYCLE. When they complete their cycle, turn the HVAC on. When you turn the system ON, the DTCs should stay off. I had to perform this several times in a row but it worked and have not had the DTCs in a long time.

You can view the actuator damper door operating shaft on the driver’s side from under the dash. See if it moving thru its full cycle when you clear the DTCs.

 

Thanks for your response, Read my very first post, I had the HVAC repaired at a local Corvette Shop. They installed a new left actuator, I watched them do it and I have the old one in my hand.

Pete

 

Thanks Bill, For your input, Now that's something I've not tried before.
These codes keep coming back every time I drive the car. And the Corvette shop just wants to put another actuator in it. Big Bux$. I'll try this and let you know how it works out for me.

Thanks
Pete

 

Gee, Pete, did you read MY post before replying to my reply? Apparently not, as you did not answer my question about the removed actuator.

 

OK, I left out that part. The old actuator taken out is not broken. I took it apart and no gears were broken. And still the codes are there with the new actuator. I'm going to try Bill's theory on resetting the codes and see if that help's. I've tried just about every thing else. Sorry about the confusion.

Pete

 

Bill, I tried your suggestion and it works. The HVAC codes haven't come back yet. I'll cross my fingers Thanks very much for everyone's suggestions I tried them all. This problem was banging my head. Thanks for everyone's help.

Thanks Bill

Pete

 

YOUR WELCOME BROTHER! GOD BLESS YOU!
