I have a 1995 XJS Convertible 2+2...the running lights including the inside dash lights go out when I use the turn indicator. If I hold the arm just so the lights will stay on. Before I order and replace the old one I want to remove and reinstall it to be sure something just hasn't come loose.

 

OK.....got a used turn signal stalk from Jagbits. Finally got it installed. Everything works!!!
