Parking lights my parking lights dont work. replaced all of the fuses in the car. they only work when i put my foot on the brake

Are the brake lights working, the safety lock on the gearshift is operated by the brake lights, if they don't work you can't get it out of park. Sequence is turn on ignition, put foot on foot brake (brake lights come on, park lock disengages). Check the brake light fuse.

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.

check your stop light fuse it could be blown out! you have to have foot on brake to remove from park. if no voltage to shifter, it will think no foot is on the brake. Check that the brake lights work, system requires brake light switch input to come out of park. if its not that. check the brake switch on top of brake pedal arm. good-day !

check for a bad brake light fuse! if not the fuse, the brake light switch operates brake lights and if bad you will not be able to shift it out of park, as well as the brake lights not coming on.! because you have to put foot on brake to do so. if bad switch, it wont let it out of park. it could be just out of adjustment also!! good-day !

The 2000 Mercedes models all utilize a Shift Interlock, which will only allow the vehicle to be shifted out of Park while the brake is applied. The way this works is that a lock pin holds the shift lever in the Park position until a solenoid is powered by the brake light circuit, pulling the lock pin away from the shift linkage. The wire to the solenoid may come loose, or the brake light switch may fail. If someone tried to remove the vehicle from Park without applying the brake, the end of the lock pin may have become jammed. Try two things: 1) Start the vehicle, put your foot on the brake, and attempt to move the shift lever from Park to Reverse. 2) If you cannot remove the vehicle from Park, are the brake lights coming on? If not, a) replace the 15A fuse for the brake light circuit, and b) try Step 1 again. 3) If you cannot remove the vehicle from Park and the brake lights are coming on normally, locate the interlock solenoid at the shift lever and make sure it is properly connected. When you put your foot on the brake, the solenoid should retract. If it does not, check for 12V at the solenoid when you put your foot on the brake. If you have voltage, replace the solenoid. If you do not have voltage, you have a broken wire between the brake light switch and the solenoid. If the solenoid retracts but you still cannot remove the vehicle from Park, your shift linkage may have become bent at the transmission linkage. Hope that's helpful! :)

Make sure you check switch in dash, when I move my switch very slowly the park lights work therefore replaced switch and everything is great.

thank you

Your brake light switch went out it also controls the shift lock mechanism.
Its located on the brake pedal and costs about 15.99

HAVE SOMEONE GO BEHIND THE CAR AND CHECK AND MAKE SURE THE BRAKE LIGHTS ARE ON, IF THEY DON'T WORK THEN THERE IS NO POWER TO THE BRAKE PARK INTER-LOCK SOLENOID AND YOU CAN NOT DIS-ENGAGE PARK. IF THEY DON'T WORK CHECK THE FUSE, IF IT IS OK REPLACE THE BRAKE LIGHT SWITCH.

If the brake light switch doesn't work then the solenoid that allows you to move the gear selector out of park is locked out, it is a safety feature required by law, jump the brake light switch with a paper clip ( verify the brake lights are on) and see if you can get it out of park, I am sure it will now come out, then either replace the brake light switch or the wiring to it, many times the wires to the connector of the brake light switch brake inside the plastic insulation, so the outside looks good but the connection is not there or comes and goes, I suspect this is the problem with your car. The solenoid I mentioned is on top of the steering column.

You have a bad switch at the brake pedal. Or a loose wire. Try light pulling on the wires on the switch at the brake pedal under the dash. They should be tight and secure. If tight and secure the switch could be bad.
