Need help.. I've read all about steering lock isues.please help
 

I took my car threw car wash at work to day and right after. My windshield wipers would not shut off. So I shut car off and tried restarting.when I did this the dash started flashing out going dead. Coming back on and off I drove it .And the hazard lights came on would not shut off .Well they would but I could do nothing to shut them off. The key light came on after I got home.
And the dash was dead at this point drove it home dead. Shut car off . And replaced battery in key fob. Car would start as soon as I pushed clutch in without hitting button. But would not shut off I took key inside away from car and it still would not shut off . After replacing the battery in fob the key light still comes on and will not start like it should if I play around it will start sometimes but still will not shut off. It threw a code for loss of communication to HVAC. Only code that is in it anyone have any ideas
Thank you

I forgot to say the steering lock has already been replaced once.
And battery volts are 13.5

And why didn't you pull the fuse right after?

Wow, that was a hard read. Doesn't sound like a steering lock failure. There's more going on that the lock failure.

Sounds a lot like you got the wiring wet. Pop the hood and look for water. If everything is dry, I'd try removing a terminal from battery, press on brake pedal for a few seconds, and reconnect battery. This resets the ECM, auto-up window operation, and radio presets. It will take a few minutes of driving around for the ECM to re-learn the engine, the window reset procedure takes about 30 seconds. The difficult part will be re-entering the radio presets.

Edit: the ECM is somewhere in the passenger footwell - check it for moisture. Not sure where the BCM is located but would check it too.

Pull the fuse

This happened after I went threw water so I'm thinking moister also. I have removed the battery cable. Only way I could get it to shut the power off . And I just got the car so I haven't removed the fuse cause I haven't had chance to look for it to remove it.

Now when I rebook up battery. And try the security light flashing and I get the lock light on the push button start and the Intel key flash if I put fob in it starts beeping with door open get clutch light but still says lock . Steering wheel is not locked can turn it .

It is very difficult to understand what the issue is there,get it to a reputable shop that has experience with the Z. sorry for your troubles :(

It now has a u0164 HVAC communication code
But car still not shutting off with button if it starts it starts without pushing button. Key light still on . Could the HVAC module cause the bcm not to communicate with the key or bcm

Sounds like you may have a dangerous car there, if it starts just by pressing the clutch down. I agree that you must get it to a good repair shop as soon as you can. It may well be water-related, but you don't know, especially if the car is new to you.

Be safe.

Possible solution: Flood damaged car.... :eekdance:

:iagree:

It does seem to tick all of the boxes on that one. Fingers crossed it's not.

If all these issues happened right after the car wash I would agree with others and think wet wiring somewhere. How long ago was the Steering Lock Box replaced? Unless it was just recently done, I don't think its that.
