When car is in PARK mode, you can start the motor, but can't get it off PARK - this is because brake lights are dead. Replaced the fuse, and all is OK till I kill the engine, after braking. Again the same...


Possibly the brake switch itself. Many cars come equipt with a safety feature that won't allow shifting from park unless foot is on the brake. If you have a bad brake switch, this could prevent you from shifting from park as well as giving the impression that the brake lights are bad. hope this answers your question. All the best.

How do you get a Buick Enclave into neutral when it's stuck in park is there an override?


Foot on the brake, turn on the engine, keep foot on brake, move out of park.

No over ride, or it would allow children to roll away.

Cant get the parking brake to release


If the car has been sitting for a length of time especially in wet regions chances are either the brake mechanism or the cable that goes to the rear brakes have rusted and seized up. If the brake actuator itself Weatherby by foot or hand brake or not moving then chances are it's something in one of those two items. You will probably need to pull off the rear wheels and check that the parking brake mechanism is free moving

2004 jeep liberty won't move when put in gear (like brakes are locked).crank it in neutral put in gear it will go till i touch brakes then won't move again.WHAT'S WRONG WITH THIS THING.


gear, is this a Manual trans? or AUTO you said gear.
what gear, please name the gear, 1,2,3,4,5 R
or PRNDL ( a/t box auto matic) what shift lever selection?
what is out door air temp, you do know brakes can get wet and freeze right?
it wont go you meant? until brakes are touched, key word won't?

ok engine only starts in PRNDL set to N??
is that it?
and then when you shift to D, the car will not move
what about the other gears.? try them all yet?

my guess (wild) is that you dont know how park lock out works.?
that you must hold the brake pedal down to shift to park or neutral.
is that it? (read operators guide?)

my guess is car is not drive-able. key point1 (a dead car)
point 2, engine starts and runs. and races on demand with gas foot.
point 3, im lost. (no trans stated or clear symptoms.)

my jeep has 6speed manual box
and the clutch allows me to start car.
on Automatics trans must be in park or neutral to crank engine.

"it will go till i touch brakes"



I read that 10 times,
my 2nd guess. the engine stalls ?

IS THAT IT, stalls means engine RPM is 0
and right foot actions are dead.
and all dash lamps glow, telling you STALL is now.

2003 S80 Unusal Braking Problem


I would check the vacuum line that goes to the brake booster behind the master cylinder. If there is a break in this rubber hose, then the brakes would take alot of effort to push and the engine could possibly increase in idle. Good luck and be safe

Engine Racing


It may be the cruise control cable - I had a vehicle do this to me before. The engine raced as soon as I started it, even in park. A couple of times, it stopped racing - then I pressed the gas pedal, and the RPMs did not drop when I released the pedal.
If it acts somewhat like that, check under the hood and find the cruise control system - it is most likely a 3-4" diameter, 5-6" long cylinder-like object mounted on top of the engine with a long cable coming out of it going toward the back of the engine. Check all of the clips on the cable and make sure they are intact, then make sure the cable is fully attached to the throttle body at the end. My cable came loose and got itself wedged in the throttle body, preventing the throttle from closing.
If the cable seems fine, check for other obstructions on the throttle body - there may be something else holding it. It may help to have somebody inside the car pressing and releasing the gas pedal (engine off), so you can see whether it fully opens and closes.
