SOURCE: parking brake pedal goes to floor

The disc brake pads are NOT used for the parking brake. The parking brake uses mini-drum type shoes inside the rear disc rotor.

SOURCE: 04 Trailblazer Will not shift out of park.

Sounds like the cable from the shifter to the transmission probable snaped. It happened to me at the emission inspection station. What a nightmare. To check this you will need some help. Have someone set in the car and apply the brakes as well as the emergency brake just incase. Get under the truck and find the cable from the shifter to the transmission. Have the person in the truck move the shifter lever from park to another gear. If the arm where the cable attaches to the transmission does not move when the lever is moved it is the cable. They are relitively cheap and you should be able to replace it yourself.

How do I get shifter out of park?


The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
?€¢
The automatic transmission shift lock control solenoid


?€¢
The body control module (BCM)


?€¢
The powertrain control module (PCM)

The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will supply voltage to the shift lock control solenoid:
?€¢
The ignition is in the ON position.


?€¢
The PCM sends a class 2 message to the BCM indicating the transmission is in the PARK position.


?€¢
The BCM determines the brake pedal is not applied according to the stop lamp switch.

When the ignition is in the ON position, the ignition 1 fuse supplies voltage to the automatic transmission shift lock control solenoid as the BCM supplies a ground to the control circuit, mechanically locking the shift lever in the PARK position as the solenoid energizes. When the brake pedal is applied, the BCM turns the ground of the control circuit OFF, de-energizing the shift lock control solenoid. The de-energized solenoid releases the mechanical lock allowing the driver to move the shift lever out of the PARK position. When the transmission is out of the PARK position, the shift lock control solenoid remains de-energized.
Your best bet is to take it to the dealer ,may have DTC'S
DTC B2707 Gearshift Unlock Circuit Low
The body control module (BCM) controls the automatic transmission shift lock control solenoid by providing a controlled ground to the automatic transmission shift lock control solenoid. The BCM utilizes a smart driver to monitor the voltage and current flow of the automatic transmission shift lock control solenoid control circuit. DTC B2707 will set when the BCM detects a short to ground when the solenoid is in the OFF state.

Stuck in park will not shift


Automatic Transmission Shift Lock Control System
The automatic transmission shift lock control is a safety device that prevents an inadvertent shift out of PARK when the ignition is ON. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
?€¢
The automatic transmission shift lock control solenoid.


?€¢
The automatic transmission shift lock control switch.


?€¢
The park/neutral position switch.

With the ignition in the ON position, battery positive voltage is supplied to the park/neutral position switch. When the transmission is in the PARK position the contacts in the park/neutral position switch are closed. This allows current to flow through the switch to the automatic transmission shift lock control switch. The circuit continues through the normally-closed switch to the automatic transmission shift lock control solenoid. The automatic transmission shift lock control solenoid is permanently grounded. This energizes the automatic transmission shift lock control solenoid, locking the shift linkage in the PARK position. When the driver presses the brake pedal the contacts in the automatic transmission shift lock control switch open, causing the automatic transmission shift lock control solenoid to release. This allows the shift lever to move from the PARK position.
Park Lock Solenoid
The park lock solenoid is a safety device that prevents an inadvertent shift out of PARK when the key is in the OFF position. The key must be in the RUN position to release the park lock solenoid. The system consists of the park lock solenoid. With the ignition in the ON position, voltage is supplied to the park lock solenoid. The park lock solenoid energizes through a permanent ground unlocking the shift lever. With the ignition in the OFF or ACCY position the park lock solenoid de-energizes and locks the shift lever in the park position.
Shift Lever Does Not Move with Brake Pedal Depressed
DEFINITION: Transmission shift lever will not move out of the PARK position with the ignition ON and the brake pedal pressed.

Wont shift out of park


probably the brake pedal switch (mounted on the brake pedal lever) starting to fail. it releases the shift lever and controls the brake lights coming on. you will need to replace this.

for now, turn the key in the ignition to the lock position (counter clockwise,) then to the off position (clock wise). In this position the brake shift interlock is disabled and you can move the shifter to neutral. these instructions are also in the owners manual in the driving section. the switch should be changed because eventually you won't have brake lights.

96 F250 can't shift out of park


NOTE: Your vehicle is equipped with a

brake-shift interlock feature. This

feature prevents you from shifting

from P (Park) unless you have the

brake pedal depressed. (The ignition

must be in the ON position.) If you

cannot shift from P (Park) with the

brake pedal depressed:


1. Apply the parking brake.

2. Remove the key.

3. Insert the key and rotate one position
clockwise (ignition in the OFF position).

4. Apply the brake pedal and shift to N

(Neutral). (If the vehicle is shifted to P

(Park), you must repeat the previous steps.)

5. Start the vehicle.


If you need to shift out of P (Park) by using the

alternate procedure described above, it is

possible that a fuse has blown and that your

brakelamps may also not be functional.


WARNING

DO NOT DRIVE YOUR VEHICLE UNTIL

YOU VERIFY THAT THE BRAKELAMPS
ARE WORKING.

check fuse 13 based on the attached diagram.

If this fuse is bad replace it. If it is not bad, blows again, or continues to be stuck in park then you need a new brake interlock switch that can be found on the brake pedal up underneath the dash.mustang_guru_2.jpg

My 1995 Geo Tracker stuck in park


Try replacing your brake light switch that is located at the top of the brake pedal arm. It might work if you wiggle or shake the switch but most likely you will have to replace the switch. good luck leave comment.

Ford Expedition 2001 that wont shift out of Park


Shift Interlock System
The shift interlock system prevents the shifting from PARK unless the brake pedal (2455) is depressed. The shift interlock system consists of a shift lock actuator (3Z719) mounted at the base of the steering column tube (3514). If the ignition switch (11572) is in the RUN position, the shift lock actuator is continually on unless the brake pedal is depressed.

Thier is also the shift lock actuator ! plus wiring . You have a short to ground on that circuit . Do you know how to Find a short ? videos on youtube .
None of the power windows work ? Check for broken wires inside the rubber boot from the body to drivers door !
Videos on youtube for testing power window circuits .
