Turn signal problem
 

So I was washing my car and when I walked to the drivers side the turn signal was on, not blinking just on. The car was not running and not in accessory mode. Checked to make sure turn signals weren't on and tried to disconnect and reconnect the battery but still on. Anyone know why? And also when I got into the car to see if the signal still worked it just stays on solid when you flip the switch. Then when I would switch on the passenger signal it started rapid flashing like a bulb was out and none of the bulbs were blinking for a minute and then they started.

Swap bulbs and see if the symptoms swap sides. If so, you need a new bulb.

So problem got worse. I went out today and reconnected the battery and all was fine until I started the car. Headlights started flashing and the whole gauge cluster was flashing and it went dead so found the problem but now the windows are stuck partially down and the car won't start.

What problem did you find?

Search this site for "window reset". You can use any of the major web search engines and add "site:the370z.com" to your search string.

The problem is the whole gauge cluster is dead so it can't pick up the signal from the intelligent key, and the car won't start or even go to accessory mode.

You have pulled the steering lock fuse or cut the brown wire, right? :ugh2:



If not, then you could have a steering lock failure. There's a thread here on how to temporarily fix it so you can pull the fuse. :icon14:




Best possible scenario: the battery died.... :eek:

If the whole gauge cluster is blank, then you've probably blown a fuse.

If "it went dead" means the car died, then it's probably not the steering lock (ESCL will prevent starting but not kill the car once going). But it would be a very good idea to check yours and remove fuse if it hasn't already been done (search is your friend).

Edit: this is starting to sound like a wiring or BCM problem.

OP, SouthArk has the FSM link in his signature, use it. Hopefully you did due diligence before buying the car; i.e. it's not a flood car or from an area that has recently been under water. :eek:



GL and let us know what you find.

Turn signal problem
 

So I've been at work and haven't been able to do anything with the car but odd enough it started today without issue and I haven't done anything to it yet. Dashboard came on and everything. The service engine soon light came on and it has code "PO603 Internal Control Module Keep Alive Memory (KAM) Error."

That sounds like it could be scrambled memory in the ECM. FSM should have more info. There is an ECM reset procedure in the FSM or you can disconnect a battery terminal and step on the brake pedal for 2-3 seconds - either procedure should clear all RAM.

If you disconnect the battery, you'll need to do the window reset procedure (search is your friend) and you won't pass an emissions inspection until you make a few drive cycles. Engine may run rough for a few minutes until the ECM re-learns the engine.
