More investigation today, I know the blue/white mains circuit is ok but the blue/red dipped isn't. I plugged in the iffy lamp pull switch brown on terminal 1 and two brown/red on terminal 3/4 that is how the wiring diagram shows and how it was before I started, the problem terminal is number 8 which should feed the interior/sides. I pulled out the switch and had 12v at terminal 3/4, good. I then took off the column stalk cover and checked the voltage at the blue/red terminal, nothing! I checked the blue/white and there was 12v. This indicated the stalk is the culprit. To placate myself I run a cable from the relay end of the blue/red to near the stalk and checked if it was broken, it was fine 0.6 ohms. So I hadn't unplugged the cable when playing with my washers.
So to conclude I think the pull switch needs cleaning/replacing but the main problem is the stalk switch. If it is the stalk then how is it removed? I can see I may have to unbolt the steering column clamp to access the cables then as I can't see any joints make my own connections to the new one?
Am I wrong.......Help Please!!!!
