No break light, can not shift gear.

If your 2007 Impala is stuck in park and the gear override silver button doesn't work, there may be a few potential problems that are causing the problem. Here are some common causes and troubleshooting solutions you can try: Brake light switch: The most common cause of this problem is a faulty brake light switch. The brake light switch is responsible for sending a signal to the shift interlock solenoid to release the shifter when the brake pedal is depressed and can prevent the shifter from releasing if the switch does not operate properly. Make sure your brake lights work by pressing on the brake pedal. If they don't work, it's probably a brake light switch issue that needs to be replaced. Shift Interlock Solenoid: The shift interlock solenoid is a mechanism that prevents the shifter from moving without pressing the brake pedal If the solenoid is faulty or a blown fuse can cause the shifter to go into park. Check the fuse connected to the shift interlock system and replace if necessary. If the fuse is good, the solenoid may need to be replaced. Shift Cable: The shift cable connects the shifter to the transmission and allows you to change gears. Damaged, loose, or misaligned cables can prevent the shifter from leaving the parking space. Inspect the shift cable for any obvious issues and make sure it is securely attached to the shifter and transmission. Shift lock control module: Some vehicles have a shift lock control module that ensures proper operation of the shift interlock system. Malfunction of this module can cause the problem. It may be necessary to use a diagnostic scan tool to check for any error codes associated with the module. Ignition switch: Faulty ignition under certain conditions

more then likely due to faulty brake pedal sensor or shift lock. when pressing the break pedal you should hear a click at the shifter even when brake pedal is lightly depressed, if there is no audible click, issue will need to be verified if due to brake pedal sensor or the actual shift lock on the shifter,

Your question is too vague. Brakes don't "lock".
Turn ignition on, but do NOT start engine. Step on brake pedal and you should hear a Click near the gear shift lever. This is the relay that unlocks the gear shift. If you don't hear a click each time you tap the brake pedal, you have an electrical problem - bad relay, break in wiring etc. You will likely need to have it towed to dealer for diagnosis/repair.

Check your brake light function. If that is at fault then your brake light switch may be faulty. If your brake lights are fine then you may have a faulty shift lock solenoid. Some Japanese models of that era have a button or key slot near to the shift lever. If you depress that then it should manually release the lock and allow you to move through the gears, until you move back to 'P' position at which point it will lock again.

Hi there,

Some automatic vehicles rely on the brake switch (mounted on brake pedal) to be activated by depressing brake pedal. This signal then operates a relay and switch, to release the gear lever.

Firstly, I would check the brake pedal switch (are your brake lights working?).

If brake switch is confirmed OK, then inspect the relay (and related circuit components) of the gear release switch.

Generally,when a shift lock solenoid/system goes bad you just zip tie the shift lock to unlocked position and that removes the need to depress the brake to shift out of park.

if you want to put it into gear,turn the key forward(not crank)
look underneath by the brake pedel
there is a neutral safety switch(not break light switch)
depress it and you can shift into gear

Have you checked to see if you have break lights. A safety feature . Most newer cars will not shift out of gear unless BRAKE PEDAL is depressed. Very common on VW's so why not MOPARS.....HEHEHE.
Good luck,Pat

For the short term and as a temporary measure, the shift lever can be released by depressing shift lock override button which is in a small hole next to the shifter, typically covered with a small piece of plastic.

A permanent fix is needed though. The transmission shifter has a safety interlock. You must depress the brake to release the interlock in-order to shift into a drive or reverse gear. This system is powered by electricity. The fuse may be blown. Check the fuses for faults. The brake pedal / brake light circuit must be functioning in order to put the car in gear. Check the blue 10amp brake light fuse. Make sure the wiring in the trunk does not have breaks that may cause the fuse to blow

safety switch on brake pedal. common cause is a wire breaking off. there are 1 to 2 wires going to this switch. It is located on the brake pedal bracket above the foot pad.
