Today I noticed that my AC was not cold on the drivers side. The passenger side was cold. I checked the codes and it has a B0361-Left Actuator Feed Back Short To Ground and a B0441-Left Actuator Out Of Range. I cleared the codes and started it and the air worked fine. I got home and shut it off and started it again and the codes are back and the AC isn't working right again. Doe anybody know what these codes are saying? I don't have a clue what to look for. Thanks in advance

 

Have you disconnected the battery recently, or has it gone dead? If so, I run into the same exact problem (same codes even!) disconnect my battery. It doesn't happen everytime, but it happens. Try disconnecting the battery for a few minutes and reconnect it. It will force the HVAC doors to go through a re-calibration again. There is a fuse pull method that has never worked for me. Once I do the battery disconnect, it's good until I pull the battery cable (and once again it doesn't happen everytime).

I really think this thread should be made a sticky, or at a minimum added to the FAQ. The GM repair method for this is to replace the A/C door actuator, which is not always necessary, and very expensive.

I can think of 2 people in the past 2 weeks that had this same problem, and a battery disconnect fixed it.

Edit - Additionally, if this doesn't solve it, take a look at the vacuum hose that is directly under the battery (you'll have to remove the battery tray). Also, I know of one person that had the 1/8" hose fall out of the back of the intake manifold. Still though, try disconnecting the battery cable first. Also, you might try clearing the codes and see if that helps.

 

I replaced the battery two weeks ago. I drove it home but I haven't drove it since till today. I'll try that. Hope it works. Thanks

 

Let us know if that does the trick!

 

You want to hear something wierd??

I have been getting the B0361 and a couple of others as well for 25K miles. My HVAC works great!!

BUT if I clear the codes I get hot air!!

Turn A/c off then back on and it works great again. But the codes are back.

Had car into dealer for other issues and told them about this. They have spent more than one day replacing something (all issues are not done so I don't have the work order yet but I do have the car until next week when I have to take it back due to late parts arrival)...I was told its very difficult to get to what needs to be replaced. But guess what....whatever they did didn't change the problem. Now I get two instead of three HVAC codes but AC works. And I get hot air if I clear the codes.

Wierd issue and wierder that dealer did lots of labor and parts and didn't change anything.

Think I should suggest to them to disconnect the battery?? Thank god its warrantee.

Hmm, I went out and disconnected the battery. I'll hook it back up in a little while to see if it works. I'll let everyone know if it works.

 

Well I hooked up the battery and so far the ac is working fine. I let it run for about 5 min. and still is cold. I"ll take it for a drive tomarrow to make sure it will keep working. So far so good. Thanks for the help.

 

I have the same codes as well. I've had it fixed under warranty once. Then the codes came back. I took it to the dealer again and they cleared the codes with the Tech 2 and the codes disappeared again. Now they are back. However, the A/C is working fine.

 

So is this another common corvette problem?

 

Which exact codes to you have? I will check mine tomarrow and list them here.

I'm not leaving my car there again for a code problem that they can't fix. While my AC work great.

Hello Mark,

Basically, you are experiencing a very common and persistent Corvette C5 A/C issue. And, from the specific trouble codes that you have discovered your DIC to be displaying on your dash, you may very likely have a faulty Left Air Temperature Actuator (GM part #89018365). This specific part is located high (and inside) on the left side of the air box in the center A/C and CD Radio console. This part is held in by two screws and a supporting slip on style dowel pin. On July 12th, I posted a solutionary response to assist those beset by this particular A/C HVAC gremlin. Therefore, please refer to the following post for further insight:
