The other day the alarm went off in my 2004 XJ8 for no reason. I turned the alarm off, but when I went to drive the car the windows did not work, the headlights did not work, the turn signals did not work etc. etc. Engine runs fine, A/C works.
Any Ideas? It is a 2004 XJ8, 40,000 miles and always garaged, new battery.

 

You need to post in the X350 forum. (big aluminum cars)
This is the X308 forum. (cars up to 2003MY USA)

 

Thank you I realized my mistake after I posted it here and I put it on the other forum. I do not know how to delete this one. Can you help me?
