95 325 is e-brake doesn't fully engage

Assuming yours is the 2 gear stick layout this is roughly how it works.
ONLY CHANGE BETWEEN 2 AND 4 WHEEL DRIVE WHEN STOPPED, IN NEUTRAL AND WITH THE PARKING BRAKE ON!!
The smaller gear shift should be to the left of the normal gearstick.
It should be in the fully forward position. This means it is in 2 wheel drive, high ratio, for normal road driving. (Rear wheels).
Pulling the stick back ONE notch engages 4 wheel drive, high ratio. Used for snowy, icy, slippery conditions as well as light off roading. (Keep the speed under 50mph).
Pushing down and back another notch engages neutral in the transfer box. This means ALL drive is DISCONNECTED even if you use the normal gearbox.
**Try to avoid this one**!!
Pulling the stick back the last notch engages 4 wheel drive, LOW ratio. This is for the more extreme off roading conditions such as VERY steep hills. Not usually used in normal day to day driving.
The two fully forward positions, (2High and 4High), will be the ones used the most.

Please be more specific. Most cars with automatic transmissions will roll forward in Drive or backwards in Reverse. If the car is on a slope, it can roll due to gravity, even backwards in a forward gear. If you mean the car is rolling when it's in Park, either the transmission is faulty or it's not fully engaging in Park. A third possibility is that you mean that, after stopping with the brakes, the car begins to roll with your foot still on the brake. That would be a brake problem. If you've had the car for a while and this is a noticeable change, take it to a mechanic and have it checked. Explain your concerns clearly.

Sounds like the shifter is stuck in reverse or drive since it will roll.
I would set the parking brake and have someone watch the shift lever on the transmission to see if it and the shifter inside is still connected.

put it in reverse and slowly go back wards to take the pressure off
the rear wheels if not its a call out to a gareg

Sometimes can take a hammer and jar the shoes loose by hitting the backing plate where the shoes ride and free up that way

Assuming this is a standard transmission, you always have it in 1st gear. Roll back is controlled by balancing the clutch with the gas pedal.

If an automatic transmission, then the vehicle should hold itself on the incline, unless it is a steep incline, to which you may use the gas pedal to hold the vehicle on the slope, and not the brake. And you would always have the transmission in the main drive gear position.

Not from up top inside the car if it's frozen.

Sounds like it's been engaged quiet tight. So start the vehicle try depressing the release button and lifting up firmly instead of trying to immediately push downward on it to release.

Do that while lightly easing the vehicle in reverse if parked downhill to take pressure of the brake or in drive if parked uphill.

2005 is relatively new and I don't presume the cable has frozen nor snapped in the engaged position.

It's common when the brake has been engaged on a steep incline and drifted forward or the wheels curbed quiet snugly to avert rolling.

The vehicle should start if you put the transmission into neutral. I would try to let the car roll just a hair, apply the brake pedal and put the car into park.

Hi their.Yes there is a place that's not to hard to adjust. Underneath the truck on drives side there is an adjustment there.Make sure nothing was broke in the slamming on the shifter..

Have her try putting it into drive, attempt to go foreward, plant her foot firmly on the brake, put it back into neutral, then try to release hand brake. Other than that, the only thing she can do is to try and warm up brake cables (shielded part near the backing plates) with a hair dryer.(in park, so it dosen't roll over her) This generally happens when water gets into cable shield and freezes Once free, spray some wd40 or other solvent into cable opening and on cables themselves.
