Brake lights stay on all the time. For some reason, they stay on... I had to disconnect the battery...any clues to why???

there is wires that go to the brake can where u put brake fluid at check to see if low or disconnet the wires and see if light gos off

Hi have you checked the brake fluid level ?

Is it possible something is keeping the brake pedal down enough to activate the brake light switch ?

check alternator out put should have 13.5 - 14.5 volts at battery with engine running.if not alernator voltage regulator faulty.any time you see brake light and charging light flashing alternator not putting out enough power to work the antilock brake system.

there is a relay attached to the brake peddle - and it is also a switch - replace it

hi the rear high level brake warning light in rear screen ? works with the other two brake lights at same time when you press brake pedal with ignition on ? so may i suggest you check the other brake lights are working ? if not ? check these bulbs? reason being that from the symptoms you describe that high level light is staying on ? it would suggest that the brake light switch at the pedal is not operating ie not putting brake lights off when pedal is off and would suspect the brake lights have been on for some time and burned bulbs out due to the brakelight element in bulbs are high wattage if you check on what i have suggested? and is the case ? come back and will advise you how to adjust brake switch easy diy hope this helps? best wishes from the uk

under the dashboard on the drivers side. look at the brake pedal lever. there should be a switch attached. push switch in and twist to remove. then pull the button as far out as it will go. while holding brake pedal down reinstall switch. then pull pedal up to top. this will reset the brake light switch. if they stay on still, then just replace the brake light switch.

First, check the brake light switch, and if the high level light is on, the brake light switch is the likely problem. Even if it isn't, the bulbs could be burnt out. Anyway, disconnect the wire harness from the brake light switch on the brake pedal. If the lights go out, replace the switch. To test the light switch, disconnect the wire harness from that (with the switch in the "off" position). Again, if the lights go out, this is the problem. More likely, it is the brake one. This happened on my Dodge twice.

brake light switch or a headlight switch

Many possibilities but the alternator is a good place to start, if its plug is loose, then the green relay inside the center console just to the left and slightly in front of the emergency brake will be clicking in connecting and disconnecting the battery( one loud click per time). It will need replacing or simply disconnecting works for the short budget.
