Glad you found the problem.
As you have found out, todays vehicles are real voltage sensitive and when you only have about 14 volts to work with there aren't many left to do the job when there's a bad ground or short somewhere. It's very importand that the battery terminals on new vehicles be kept clean, tight and free of corrosion.

 

Well here I am 8000 miles and 6 month later...HummerlessGM bought mine back and gave me the full 12,000.00 bucks I had into it[8D]
And it was all done without an Attorney so I made out with with every dime of it.

Like I said before...make them fix it or buy it back. Don't take no for an answer.

 

Lots of good info here. Glad to hear you got your defective rig returned DonWilms, shame though. I will remember this thread if I start having electrical problems.

Just started having this problem. Guess I'll have it towed to the dealer tomorrow.

 

Got it back last night. Replaced the BCM and installed a new battery.

 

hey there Im having the same problem with my locks it wont move at all and the windows on the drivers side wont go down but the other ones work. what happened was my car wont start due to the cold weather here -40c so i called CAA to check the battery and we found out that the battery is weak already so i bought a new one and installed it the day after.

so when you went to the dealer did they tell u what they did? and how much did they charge you? thanks
