BRAKE LIGHTS STAY ON WHEN FUSE IS IN - 1989 Oldsmobile Cutlass Supreme

look at the brake pedal there is a switch connected to it with a plunger to turn on the brake lights the stopper for the switch probably has fallen out you will need to stick a new one in.It is a very cheep easy fix.

In Canada it's mandatory to have DRL(Daytime Running Lights). Your Corolla probably has this feature built in. it is a safety thing however I can understand you wanting them off if it's not the law where you live.
In our 1998 Corolla, I use the parking brake all the time - every time I park - and I've noticed the lights do not come on until I release the parking brake after starting the motor. When I park the car, until I shut off the engine, the lights stay on regardless of the parking brake status however, if I shut off the engine and restart with the parking brake on, the lights do not come on.
If you "adjust' the parking brake switch(i.e.: make e-brake light in your dash it stay on all the time) your lights will not go on until you turn them on via the multifunction lever(left side of wheel). This of course negates the benefits of the e-brake light working correctly (warning you that your e-brake is on or that your brake fluid level is low) which in itself is not so safe!
There is a fuse/relay (I think) in the big fusebox under the hood that has a DRL "spot", you might want to check if you can remove it and still turn the lights on manually when you want them on. Alternately, there is a fuse in the interior fuse box(in Canadian models anyway) labelled DRL. When that fuse is out, it seems the lights only turn ob when I turn them on manually.
Hope this helps and God bless,

Now you need a wiring diagram
One look from fuse toward the problem,you got the answer

look for the relay in the under hood fuse box use the chart under the lid it is mark as (CHMSL) this is the brake light relay that is bad replace it

The brake light switch is located is located under the
dash, at top of the brake peddle.
To test the sw, use a 12v test light check for constant power out of the switch, with nothing else on. If there's pwr. out replace the switch.
Hope this helps. Good luck

check the brake light switch on the pedal

I would definitely go after the brake light switch under the L/S dah at the brake pedal . Sounds like it might be sticking. Hope this helps

yes, replace the multifunction switch.

check the brake light switch at the top of the brake pedal and if you have a keyless enter keypad on the door check that for shorts and go through the car and make sure nothing is left on

Switch is on the transmission and fuse is the parking light fuse
