Faulty – Diagnosing a Faulty Rear Window Switch and Dial Circuit on the 1970 Jaguar XJ6

The workshop at Bridge Classic Cars has been working on diagnosing and fixing a couple of issues with the electrical system of the 1970 Jaguar XJ6.

Firstly, the team carried out a repair on the printed circuit for the instrument dials. Our technician John carefully repaired the circuit before testing the component and found all was working correctly.

Then, he could turn his attention to an issue with the rear heated screen. John traced the fault back to the switch which controls the circuit. The switch was stripped apart, cleaned up and retested. All was ok after the repair.
