1999 Range Rover V8 All Wheel Drive Automatic 97,200 miles
After recently having head gasket changed (in which the battery was disconnected), the alarm system would not dis arm. Once that was remdied, the climate control panel and the radio stay dark / blank. I feel heat but not LED. The radio will start only when the on button is pressed but then will not shut off wehen car is off. How can this be fixed?
