2003 G500 - Please help with these electrical problems
I have a 2003 G500 that is beautiful and runs amazingly...except for these electrical problems. I have had it to the dealer and independent shops but nobody seems to be willing to spend the necessary time to track down the cause of this problem. Hoping someone here can help.
When I park the car, I can lock the doors and arm the alarm and everything seems fine. Occasionally, when I return to the car (if I haven't locked the doors), as soon as I open the door I get a beeping noise and the display reads "TC in Neutral." In these instances, I can start the car and everything seems normal.
If I lock the car and leave it for a while (overnight), when I return the remote does not work to unlock and disarm. I have to use the key. I will also get the beeping and the "TC in Neutral.".
If I leave the car for more than a few days, it will not start. There appears to be a slow drain on the battery.
I'm assuming these things are all related? Is the Transfer Case alarm causing the slow drain? Is there a way to bypass this system entirely? I have already replaced the rear SAM and spent a ton of money trying to diagnose and repair this problem with no luck.
Thanks for any help.
