The thing to do is determine if you have an N82 behind the glovebox or alternatively the car is pre May 1997.
One way : Drop the fuse box down and have a look at the layout. If it looks like the one pictured in the pdf workshop manual in Vol 3 section 55-3 page 2 you have the earlier car and the instrument pack controls the interior lights ( a good reference is the double length device N11 on the left side of the fuse box ). If it looks like the fusebox in Volume 3 part 2 s55-3 p2 ( the more compact fusebox without the double length N11 on the left ) then you have the later car with N82.
If you have the earlier car, drop the steering column as low as it will go ( using the adjuster ) and remove the instrument pack ( 2 long allen bolts ).
Disconnect the two connectors ( white & green ) and check the lights. If they go off then they are being earthed by the instrument pack.
If you have N82, you're probably going to have to remove the glovebox ( I don't think you can get to N82 with the glovebox in situ and disconnect the two white connectors. Again, if the lights go out, they are being earthed by N82.
In both cases, if the lights do not go out, then there may be a wiring fault somewhere or the lights are finding another path to earth.
Did the bodyshop do any welding to the car?
