l lost my turn signals and flasher one week ago, now my rear stop lamps are not working. l was told all lights are controled by the light control module. Is this true?

As far as l know, NO the brake lights are commonly on a different circuit on most vehicles because brake lights are a simple on-off circuit you push the pedal they come on when you let up they go off. However without looking at the schematic for that particular car l cant say for sure. Check the fuse box or your owners manual fuse description if it has a fuse for taillights it is on a separate circuit and not common with the turn/flasher relay.

=no= check your stop lamp fuse=
