On my 1993 16V MX6, my small lamps (parking lights + dashboard light + license light) doesn't work anymore. I take the tension at the TAIL fuze, there is 0v when the park light switch is off and 12v when it is on. So I think it's not the switch but probably the TNS relay. And I can't verify it since I don't find it in the car !!!
The TNS is not in the fuze box (it seems that it is between horn relay and EGI main relay in some 1993 models, but not mine) :
There are 4 others relays in the motor bay.
A big one under the fuze box :
Two at the left of the fuze box :
These seems to be for the fans.
And one at the left of the motor bay :
Neither of these seems to be the TNS relay !
According to some wiring diagrams (the Haynes one), the TNS relay has one green cable, two White/Blue and an orange one. On my tail fuze, the 12v comes by a White/Blue cable :
so I think that Haynes wiring diagram is closer to my car than the Chiltons one (four orange cables for the TNS relay !).
I looked everywhere in the engine bay, but I didn't find another relay. Il look also around the interior fuze box but didn't found it.
Does someone know where is the TNS or small lamps relay on a 1993 2L 16V MX6 ? By the way I didn't either saw the Headlight relay !
