Wont shift out of park and i have no brake lights

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

the brake light switch controls the shift lockout solenoid. perhaps this brake light switch is ajar or misaligned or inoperative. check to see if brake lights are working. there is an override to the shift lever lockout.

Hi, Check your brake lights, and other lights. On another truck of mine it did that and my brake lights were out so it locked the shifter until I fixed them. Hope you figure it out.

what car, you never said? NOR YEAR?
park lock out feature;. its broken , they do that. (BTSI system)
got A/T? or M/T both auto and stick shift have lockout.

no car/year, you get the generic answer.
there is a park lockout DEFEATER on most cars, (never on new cars,due to federal bs)

on the shift console, see the defeat device.
the operators guide covers this. its for EMERGENCIES.
pick one.

the A/T box,
Brakes + handle button press, unlocks BTSI

on 2005 and up , no bypass
if the key gets locked too, that tells you what is bad , on newer jeeps
on newer jeeps read this

this feature (pain) has many failure points.
any cable that jams, there are 2 , one to tranny or ignition
switch. and the brake solenoid unlocker in shift handle.
and the button, to unluck shifter, brake switch (no brake lights/)
to diagnosis it is easy , dismantle the console at shifter
then disconnect cables to find if one is stuck, (easy huh?)
and defeat the solenoid, by hand or 12v applied. and check the button
that it does in fact release.
NOT PARK LOCKOUT: (for if not on flat ground?)
reason 2 , driver, parked on a hill with tire to curb and did so
not setting brakes first (or bad ebrake ) and now the tranny parking
pawl is jammed , opps. so wiggle the steering and wiggle shifter,
or have some one push car forward (parked up hill on right) to release
parking pawl. (or gorilla it, ask bubba to muscle it out of park.)
if down hill , well, you get the idea..... pain.. gotta love A/Ts not.
Folks in Sanfranciso, just roll eyes at you, new in town>?

now the grand cherroke,, why not post car model, and year, dang.

quote 2010 oper guide, get one.
Brake/Transmission Interlock Manual Override Your vehicle may be equipped with a shift lock manual override. The manual override may be used in the event that the shift lever should fail to move from PARK with the ignition switch in the ON position and the brake pedal pressed. To operate the shift lock manual override, perform the following steps: 1. Turn the ignition switch to the ON position without starting the engine. 2. Firmly set the parking brake. 3. Using a flat-bladed screwdriver, carefully remove the shift lock manual override cover, which is located on the PRNDL bezel. 4. Press and maintain firm pressure on the brake pedal. 5. Using the screwdriver, reach into the manual override opening. Press and hold the shift lock lever down. Interlock Manual Override end quote.
no all jeeps have this,

i cant remember if this car had console shifter between the seats. but the problem is the shift lock solenoid . usually mounted in the console . it gets a signal from brake light switch to energize the shift lock solenoid

repair:change ignition tumbler ,part that key inserts into

check the fuse for your brake lights, check your brake light switch. If the brake lights don't go on your car will not shift out of park. The shifter should have an override button. look for an access hole (cover) near the shifter, pop the cover off and push a pencil down there to shift. check your owners manual for specific information on the use of the override button

no override button. if all the fuses are good, then if i remember there is a switch by the shift lever that when you step on the brake it enables you to move the shifter.good luck

check your brake lights also, if none then you need to repair the wire that connects to the brake light switch at the brake pedal.....and or replace the brake light switch

check to see if your brake lights work. the brake light switch operates the shift interlock.
