How do I fix brake light no light in rear - 1998 Subaru Legacy

brake lights in rear of car? or brake lamps in dash? ??cluster.ABS? I can't see where your eyes are looking.
if rear lamps fail IN ANY WAY, that kills dead Cruise by design. so fix rear brake lamps first.
so fix the brakes in your other post.
and your engine is
4.2Liter, inline 6, 2 cams, 1 cmp and has VVT
and VVT is failing I BET!
I'd fix the engine first, for sure VVT failing
is never good and for sure if cam is now out of time by 25degrees.(VVT stuck hard max , jammed)
tell here eyes are looking and win

brake lamps will not TURN off.
brake lamps stuck on all the time.?
they never need key on to use brake lamps.
the brake fuse is hot all the time. is why.
and is a safety rule this ,just like head lamps.work key off.
if stuck on rear brake lamps
pull the switch, plug at pedal switch
stuck on NOW????????????????????

Check that the switch is closing fully when pedal is up. There is a small spring connecting the switch to the pedal. If this is ok replace the switch.

trace the short and fix it is all i know

one element is for brakes/turn the other one on the same bulb is running lights how ever the part about brake lights go threw the turn signal switch the turn signal switch has diodes in it so that both rear light don't light up when turning i hope my explenation helps and yes some years gmm had bad tail light circuit boards you can test the connector at the lens housing with a test light there is also a plug connector where the bed meets the frame in the rear

Sounds like brake light switch is bad. It's mounted just above your brake pedal under dash. It's a pretty simple fix, unplug couple of wires and unclip switch, reverse to install.

I have same problem and have found the lower light to have a malfunction in the socket. Mazda says replace brake harness. Cheap fix junk yard but same prob can come back. Also does your cruise work? may be related to switch on brake pedal.

Most likely a bad earth to the light's. Re-earth the tail lights should sort the problem.

you prob got a trailer plug prob bad wires if not tail lights run through turn signal switch tell fix ya bout me ok

you have a badbrake light switch

The problem is the turn signal/headlight/hazard switch assembly on the steering column which the brake light wiring runs through. The part is easy to change and cost about $50 at most parts stores
