Hi,

Are you in Florida? If not, it may not show it was in a flood. If you are correct, that is why you are having crazy electrical issues. Salt water isn't nice to electronics and wiring.

I think you got more miles out of your other one than anyone has before. Usually, by 200K they were really tired. As far as the sand, if you are in Florida, could the vehicle have been used on a beach?

No, I’m in New Orleans so I’m very familiar with flooding obviously. So, it struck me immediately at the sand I was seeing. Now I didn’t see anything like sand when I looked at the car and once o vacuum, you’ll think okay I got it all heck no give it a day you’ll see it resurface all over again.

Hi,

If that is the case, I suspect your thoughts are correct. Ugh! Anything to make it a little more difficult.

If you have a chance, keep me in the loop. I'm interested in knowing what you find.

Take care,

Joe

So, I assume this is part of the problem.

Hi,

The code is likely indicating a problem within the HVAC control module or the body control module (BCM). In this case, the BCM isn't receiving a signal from the HVAC module. If both parts are functioning, it sounds like they are, there could be an issue in the controller area network (CAN).

I don't know how familiar you are with the CAN. The Controller Area Network is a communication protocol interconnecting electronic control units (ECUs) within a vehicle. It allows different components and systems in a car to communicate with each other in real time. In this case, the BCM isn't communicating with the HVAC module. That leaves diagnostics to help narrow things down.

If you look below, I attached diagnostics specific to it. Take a look through them and let me know if you are comfortable performing them.

Take care,

Joe

Any chance I created that code when I pulled that 7.5a fuse? I just thought about that.

Also, I cleared the code and it’s not come back on, but I also have no heat on either side now for some reason is any of the things you just referenced under the steering wheel that I could have pulled on by accident? Now I did take that cabin temperature sensor off and sprayed it with mass air cleaner ABS allowed it to dry out.

Joe,

The yellow wire on the knee airbag is that wiring tied into the actuator in anyway? I ask only because I just noticed the yellow wire is completely detached from the connector. Makes me wonder if it works or not because I have no codes for that all this time. Unless it’s been barely connected and just finished itself off

Hi,

The yellow wire at the knee airbag isn't related to the HVAC. That is the return signal to the restraint control module (RCM). See pics below.

Let me know. Also, if that wire is damaged, the airbag light should be on.

Take care,

Joe

Okay, I'm shocked. But I have heat on both sides. The driver's side isn’t exactly what the passenger side is but at least I know what I did etc. So now just a few small adjustments probably. So, I was against busting open these new actuators but like a light bulb went off if the cam shaft is off then the original setting on the new actuator isn’t going to be correct. So, I busted it open and felt like it was in the open position so I shut it (so I just realized also there’s only two real setting on that. Either open or closed. I was thinking it had a position for each setting) so I opened the new actuator moved it to line with the cam shaft honestly didn’t expect it to work that I even forgot to test it after I got it back together because it’s such a pain to get one screw in on this thing. That I went to Walmart to buy a test light and just naturally turned the heat one and nearly fainted in shock, lol.

Hi,

It sounds like you found the issue. If its working, chances are that was the problem all along. This is good news.

Let me know if anything changes. Also, feel free to come back anytime in the future.

Take care,

Joe

Hey, please tell me I bought the right connectors for that driver knee airbag that had the broken wire pulled out of the connector.

Hi,

That indicates it is a clock spring connector for the airbag. I'm looking at the schematic and the airbag wiring goes to the restraints control module. Is the connector at the airbag the same?
