Relay located behind fuse box.

Hopes this helps you.

take off cover to fuses in the centre consol reachin and push down the large black relay i get this myself on my volvo 940 1991 this relay does a number of things but to long to explain

The brake light actual sitch is down by pedal, but if you dont have any brake lights at all it is most likely the relay, this is located behind ashtray and fuse box cover, it is big red relay,marked with letter A. change it.

dim lights are generally bad ground / rusty -loose ground points or wires

behind fuse panel big red round relay and you can normally solder bad connection inside if you look close
