1 Alternator/generator/regulator problem

Failure Date: 07/06/2017

My a/c runs at will. Off and on by itself. Running, stationary, and in motion. My headlights come on when I put the car in drive ever though they are turned off. My alternator was replaced and the battery and all checked out fine at two local parts /battery stores July 18th 2017. Both were replaced in may of 2016. The display panel for the a/c shows both the fan icon and the auto icon. The auto icon will not turn off. Searching on line for complaints about this make and model show many others with this problem and no answers. This began July 6th and is happening more frequently as in several times a day.

3 Alternator/generator/regulator problem

Failure Date: 11/29/2011

The window regulator on the rr window of my 2005 Cadillac Deville is refective. My window is down and won't come back up although the motor power is running to the window the regulator is broken. I have checked the complaints and noted that there are several complaints regarding defective window regulators on this model of Deville which in 2002 through 2005. I called the dealer and they knew exactly what the problem was and said it would cost over $500. 00 to replace. This is only one window. There is the possibility that this could occur three more times. I know several people with this model Deville ( not this year) that have the same problem but can not afford to get the part replaced consequently they are driving around with no window in the back. I feel this is unsafe for children and pets. As well as dangerous for leaving your car out. I would appreciate if you would check into this. I think it has not been addressed because the complaints appear to be unrelated. However taken as a whole for all the years it is significant. I you look at the window regulators you will see the problem. I do not know how to get Cadillac to address this problem.
