2007 Cadillac SRX rear tail light stays illuminated after taking foot off brake, also comes on and off, flicker, without brakes depressed.

What's a DHS ?
Stop Lamps

The STOP LP fuse in the rear fuse block supplies battery positive voltage to the normally open stop lamp switch. When the brake pedal is pressed, the stop lamp switch contacts close and battery positive voltage is supplied to the center high mounted stop lamp (CHMSL) and the turn signal/hazard flasher module stop lamp switch signal input. In response to this input the turn signal/hazard flasher module supplies battery positive voltage to the left and right LED tail lamp assemblies. The CHMSL and left tail lamp have ground at G402. The right tail lamp has ground at G401. The stop lamps illuminate when they receive both power and ground.

the brake lights will come on when the brake light switch senses air pressure in the switch
That will disconnect the cruise control as it reads that you have put the brakes on
The application pressure I take it is the pressure in the brake lines when the brake pedal is depressed
I would be looking at a leaking valve in the foot brake treadle valve

Fully Depress the brake pedal before trying to shift into gear. Modern cars have a lockout for safety reasons.

Sounds like you have a blown fuse. Check owners manual for location of fuses, should be under steering wheel.

Hi,
check the brake light switch located in the brake pedal area. Normal procedure is to remove the two wires and connect a jumper' wire between them, check and see if the rear brake lights operate. Check the brake light switch and see if it is adjustable. If so, re-connect the removed wires, adjust the position of the switch untill the brake lights operate,when the brake pedal is depressed, then secure the brake light switch.

that should be warranteed..but check with obd2 get code maybe wheel sensor

The brake lights on a 1993 Toyota Supra are located in the rear of the car.
As you stand behind the car , have a friend put his/her foot on the brake pedal. This will illuminate the tail section of the car and indicate where the lights are ...

Tail lights or brake lights? if it is the brake lights then the light switch is malfunctioning or is stuck. it is usually located somewhere on the arm of the brake peddal. When you depress the brake peddal it pushes the switch in like a doorbell button and take your foot off, it releases and the lights go out.

sounds like wireing is shorted together. you need to trace down wires and check for bad spots in wireing. also be sure and check plug if you are set up for trailer lights.

no disrespect but....
Check the book and make sure you are using the proper bulbs on all sides. (3957 looks just like 3956 but wont work right)
