In drive or neutral they are on all the time. In park they work just fine. bulbs changed and brake switch changed with no effect. This is a real problem when I drive around and it loks like I am stepping on the brakes the whole time. this happens regardless of whether I have my headlight on or not.

Re: brake light on all the time.
Obviously their is a fault on the gear selector wiring but where ,because the stop light switch is used to control the gear selector.suggest dealers because some dealer fitter with product experiance will know exactly where fault lies

If the dash lights are on the same circuit as the park lights. Chances are if no dash lights... no park lights. Unless the dash light dimmer switch is on the low position. Check park light fuse. If no brake lights... which are on a different circuit and you are sure the bulbs are ok check brake light fuse. If fuse ok, unplug brake light switch at brake pedal and cross the terminals with a jumper. If brake lights work, the brake switch is faulty. If still no brake light operation suspect a wiring issue
forgoet auto whatever there only as good as the mechanic standing in front of you ,??? know what i mean ??? remove rear light clusters if reverse on both sides or one if only on one side then check the bulb holder as iam pretty sure its a bad earth or ground problem ,but then as stated the answer is only as good as the person in front of you and from this distance i cannot see a thing ,iam in spain .alicante to be precise
There is no adjustment. The park lights are on a different circuit than the brake lights.
Do you have a third brake light that works. Its also on a different circuit but works from the same switch. Do your turn signals work. They use the same filament as the brake lights.
Also, the brake light circuit goes through the multi function (turn signal) switch.
Since the brake lights and turn signal lights use the same filament in the bulbs, the brake light circuit will pass through the turn signal switch. When a turn signal is used it cancels out the brake light for that side.
Let me know if your third brake light and turn signals work in the rear.
Also, if youy have not already, check/change the bulbs. The type of sockets those lights are in also get burned so look at them well.
brake switch on the pedal bad.bad relay. do you have a second fuse box if so check it. look at the wiring see if it is frayed or chafed check the connections.check all the fuses not just the ones labeled brakes.switch the relay with one that you know is good like turn signal and see if the turn signal works then check brakes.use a 12 volt test light check the brake switch and probe the wires. hope this helped if not write back and i'll give you more ideas.
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.
