Good Afternoon,
I am having problems with my 2007 buick lacrosse 3.8 liter key fobs. They do not work at all replace fobs and batteries but they will not program. I think it is the reciever? Can any one tell me where it is located? I have also had electrical issues. The lights on the dash and radio sometimes fade out and now I just changed the oil and I can not clear the "change oil soon" warning that comes up on the dash. I am wondering if this is all connected to a wiring issue or some sort of control module. Any Ideas or suggestions would be greatly appreciated. I love my buick I bought it 3 years ago for 4grand with 42,000 miles it now has just over a 100,000 with no rust and I want to keep it as my daily driver for years to come.
Thanks for your help
Andrew
