Here is something that might be related to your issue, carefully inspect fuse box under dash, driver side. See if it is wet/moist with oily liquid on fuse side and wire side behind. If it is, its brake fluid from the brake master pressure switch that has failed causing brake fluid to be pushed thru the wiring all the way to the fuse box , shorting out the electrical system. The repair would require replacing the brake master pressure switch with an updated pigtail (supplied with new switch), and replacing the complete fuse box assembly, and I would recommend cutting and splicing new wiring from the brake pressure switch to the fuse box.

I have a 91 ford f150 and the brake lights wont work and the rear right blinker is dim. Can you help me?

Check System Fuse - A fuse is used to protect the brake light circuit from amperage overload. If the fuse has failed it will not allow the electrical current to continue to the brake lights. To check the fuse, first locate the brake light system fuse in the fuse panel which is either under the dash or under the hood in the power distribution center. Connect the test light to a ground like an engine or dash bracket and turn the ignition key to the "on" position. Using the test light probe both sides of the fuse. If the test light illuminates on both sides the fuse is okay continue onto the next step. If one side of the fuse illuminates the fuse has failed and needs to be replaced. If the fuse fails as soon as it is replaced or when you apply the brake pedal the brake light electrical circuit is shorted to ground. Rarely a system short can occur, a car repair manual is needed to find the wiring schematic for the brake light circuit. Once the brake light wiring has been located inspect and repair as needed.

Check Brake Light Bulbs - All cars have three brake light bulbs that create the brake light illumination affect. If all of these brake light bulbs fail no brake light operation will occur. I know what you're thinking, you might say all three brake lights at once? But in reality one brake light went out at a time and you did not notice. People only tend to notice something when they almost run into the back of your car to help persuade them to inform you the brake lights aren't working. Remove any of the brake light bulbs to confirm the bulb is okay or burned. After the bulb has been removed inspect the filament and replace if failed. If the brake light bulbs are okay continue to the next step.

Checking the Brake Light Switch - A control switch is used to connect the brake light electrical circuit. This switch is located near the brake pedal lever. Basic switches have just two wires, power in and power out to the turn signal switch. Use a test light that is grounded and with the key in the "on" position test for power at one side (wire) of the switch, then press the brake pedal while testing the opposite side (wire). It should illuminate the test light, if electrical power is connected through the switch go to the next step. If no power is detected through the switch the brake light switch has failed and replacement is required. If your car is equipped with more than two wires integrated into the brake light switch a car repair manual is needed to locate the proper brake light circuit wiring.

My brake lights are staying on and drained my battery!!!! could it be a fuse??

the fact that you have lights means your fuse is good-lights all the time means your brake switch (located above the brake petal) is hung up or stuck. You need to get down low enough to see it, under the dash and immediately above the brake petal-as you push the petal with your hand, you will see it attached to the brake linkage-for some reason, it is always 'closed' which causes the lights to stay on, even with the key off (safety reasons, this circuit is always hot). you should be able to 'unstick' it by manipulating it, or you can spray a light coating of wd40 on the assembly to sree it up. Worst case, you will need to replace it, the usually run under $20.

The shifter will not release from park, is it the cable, electrical or what


Check to make that the brake lights are working - shift interlock is in the same circuit - could be a bad fuse.

You can try turning the key (with engine off) o

to the first position (Unlock) shift to neutral to start vehicle and then shift to "Drive or Reverse"

Brake lights won't come on changed switch and checked fuses under dash are there more fuses

Remove the brakelight bulb holder, If you pop out the entire assembly it will save your knucles some skin. Then you want to take some fine sandpaper and clean the contacts "on the housing" well, and coat the with a thin film of dielctric grease or vaseline. I'm sure this will resolve your problem. I've had to do this to numerous Volvo vehicles over the years. Also once you're finished, the dash indicator may "not" go out unless you purchase the bulbs from Hella because of their candlepower exclusivity.

Take a look at the wiring to the brake lights. It is quite possible that over the years one of the wires has rubbed against another enough to short out, causing the blown fuses.
