For the last week the rear brake lights on our 1992 Diahatsu applause 4 door hatch won't turn off including the eye level indicator in the rear window. It is not a head lights issue as they work correctly, and pushing the brake peddle does nothing as well. I have checked for relays there are none, I have tried disconnecting all wires connected to the brake master cylinder again nothing

Re: Rear brake lights always on
Classic brake switch problem. Easy fix switch under brake peddle unplug wire f ROM clip and its like a switch with little button on top. Switch may b fine. Had same problem and there's a rubber bushing inside that just wears out after yrs of use. 5-10 min fix. Let me know if worked for you or not. Thx.
I had the same problem with my applause ! At the top of the brake peddle there is a switch that turns the lights off when you release the brake peddle ! It is not connected to the peddle itself , but on the peddle is a hole at the top that is supposed to have an adjustable plastic bolt in there that pushes the switch in when you release the brake , switching the lights off ! If this has Broken & is missing , there is nothing to push on the switch & your lights stay on ! I just found a small steel screw I could tightly scew into the hole on the brake peddle , so it would make contact with the switch & problem fixed !

If the other brake lights work, probably broken wire. Eye level meaning Suv hatch? If so, the wires tend to break at the rubber boot from the hatch to the body. The reverse lights run threw the neutral safety switch on the transmission. Could be a broken wire, most times it is the switch.

although I have not experienced this problem in the exact vehicle you have, General Motors has had problems with the turn signal switches in many of their vehicles. The turn signals may still work properly, but the electric signal from the brake light switch passes through the turn signal switch (also called a combination switch) before it goes to the brake lights. I assume you have no problem shifting out of park or you would have mentioned it, which tells me the brake light switch is functioning properly. First thing to do, as always is to check for blown fuses. If it is a blown fuse, you then need to determine what caused the fuse to blow. If you have towed a trailer recently, it could have been faulty wiring in the trailer, or it could be faulty wiring in the trailer lighting harness of the Escalade.
Possible that the wiring harness to the rear is having a short from the hatch door switch to the brake light assembly . It can also be a wrongconnections if there was some work done on this area that needed the harness to be rewired. So check this out, remove and reconnect.
use a multimeter to check the drain of the battery to confirm the short when the line is detached.
Please check my link for tips on battery drain.
same thing happened to us. My wife came home and said the rear brake lights were stuck on so I assumed it was the brake switch...not so. Took car for a ride and noticed rear wiper did not work and when I hit the brake the rear hatched opened and door locks blew out. I started by looking at the wires in the gromet above the hatch and found almost all the wires were bare. Therefore power was jumping the bare wires and traveling back down the third break light and to the rear brake lights and visa versa.. a very dangerous situation. The best that I can tell is the wires are so short in length that they pull and chafe every time you open and close the hatch...very poor design... Note: we bought our vehicle brand new and some of the wires had electrical tape on them....seems mickey moused.
hi from uk the fault you have on rear nearside/left lights is a sure sign that you have a poor earth on the left rear lamp assy also check the connection block on the bottom crossmember where the hatch closes on there are pins on the hatch that when closed they contact the block on crossmember so ensure these contacts are clean? the block on x member is removable and lifts out it has plug attached check wires for corrosion? and any sign of o/heating on plug/wires usually caused by poor contacts resulting in arcing /short circuit
1. Remove 2 plugs attaching liner to body to right/left of left/right light assembly. 2. Gently pull back liner to expose rear of light assembly. 3. Remove three 10mm nuts from exposed bolts. 4. Assembly now held in place by a plug in assembly that goes into a white plastic plug that extends into trunk under single bolt [See no. 3). 5. Pull to rear with wiggle movement to pull out plug. Takes a little while.
check your brake fluid level i had same problem on a different car with handbrake light staying on and when i checked brake fluid it was on minimum light went back to normal after topping up fluid in the reservoir check the fluid "DOT" rating before buying this should be on the cap (ie DOT 4 fluid only)
sounds like brake pad sensor damaged or did you forget to put in new pads or removed? if its got one.
low fluid in brake reservoir can cause light to stay on also
or hand brake light switch shorted to earth have seen coins jammed in there b4
