Hello everyone. I have a 1993 XJ6 which is experiencing a few electrical issues. The signals do not work on the exterior, nor dash, and the rear defroster, power lock button, and windshield wipers do not work as well. Some initial testing shows that when I activate the wipers they are sending a signal. And the wipers can manually be triggered. Same goes for the signals. I'm thinking it must be the central processor.

Has anyone had a similar issue and know what the problem may be? Thanks!

 

did you get the car like this? did it all happen at once? on piece at a time?
i would check the wiring in the column, i had my horn quit on me once because of a bad wire crimp in there. for the wipers check the fuse under the passenger knee panel, its the only in line fuse there. but as far as i know none of this is controlled by the ecu. good luck

 

I actually received the car like this. So I'm not sure in which order the malfunctions occurred. I'll try the fuses this evening and see if that helps. Thanks!

 

Get your hands on the Haynes Jaguar 89-94 Repair Manual. There is good info and pictures of the whole setup, including wire diagrams.
