Hey guys!
HELP! What has happened to my baby? My 2004 XJR just decided today to give me grief.
I do not have access to

1. Glove Box (where my helpful manual is located;-)
2. All windows and sun roof.
3. All front lights: (Low beams, High beams, Turn signals, markers, etc)
4. Valet button

And who knows what else. I was hoping to make a long night trip tonight....
Thoughts? Its clearly to wide spread to be the fuses.

 

Hooray! Phil Lynch saved the day, again.
Gave him a call and he suggested the craziest fix that I perform once a month to remedy other situations: disconnect the (-) terminal; touch the lead to the (+) terminal; then reconnect.
And TaDa! Magic. The car purrs again, with everything intact...
Sometimes I want to ring her bloody neck;-)

 

Check the to see if one of your power feeds going into the Front Electronic Control Module is good. You could have a broken wire or a backed out pin at one of the connectors at the control module. The module is behind the trim panel where the hood release is on the left side.
