Check the wire to the brake light switch. it can look ok, and be broken inside.Take the connector off of the switch. Hold the wire with both hands, and one at a time, pull the wire to see if it streches. The insulation will break if the wire is broken inside

1999 ford escort, parking lights don't go to off, brake lights stopped operating

Could be caused by stuck contacts inside the park lamp relay . The brake light problem could be caused by a faulty brake light switch . This switch is on top of the brake pedal . Check for B+ voltage with a voltmeter before replacing the switch .
The park lamp relay is in the relay box Relay Box
Behind left side of I/P

1970 thunderbird... My electric windows wont go up. Where is the fuse box. Located at. and my interior lights dont. Go on.either i need help

Well the fuse box is under the dash near the brake pedal.
The power windows should get power from a circuit breaker that may not be in that box. The interior lights may get power from the cig lighter circuit. You can check for power for the lights at the door jamb switch, or the headlight switch.

My Brake lights won't work on a 1998 Volvo S70

There are several possible reasons. Obvious ones might be checking for fuses that are burned out. Second would be making sure you are getting good connections to your brake lamps (all 3). Third, check the brake light switch at the pedal. And last, Volvo Part Number 9442303 is a brake lamp failure relay that can go bad. It's not inexpensive, but probably more than likely the issue. One way to check is to find out if your cruise control works. If it does not, it is likely the relay. It is grey and flat on all sides. Earlier model Volvos had round red ones. Check the location in the service manual.

Let's find out before i get rear ended @ 70mph

Does the CHMSL ( Center High Mount Stop Lamp ) work ?

If this does not work, check the BPP ( Brake Pedal Position ) Switch, mounted on the brake pedal lever. There should be 4 wires to it, 2 are for the shift interlock, the other 2 are the brake lamp switch.

The brake lamp switch feeds direct the CHMSL and the MFS for the Stop/Turn combo lamps.

Without a CHMSL, I would suspect the BPP switch.

The wire colors on the F-150 are Light Green & Light Green w/ Red stripe for the stop lamp circuit. If you have this color combo, unplug the connector, and try jumpering the 2 together, to see if you have brake lamps.

Assuming the mechanic already checked the fuse for the BPP

Can't shift into reverse.

There is a brake lamp switch located on the brake pedal itself, this also works as the shift lock release.

Brake lights don't work on 1988 Ford Thunderbird

Check the brake light switch located under the dash, connected at the junction where the master cylinder rod connects to the brake pedal. Remove the connector and with a short piece of wire, paper clip works fine, insert into the two terminals on the connector. Check to see if your brake lights are on. If they are, your switch is bad.

1988 ford thunderbird brake lights and turn signals not working

When this happens the problem is most likely the multi-funtion switch aka turn signal switch. Check to see if the 3rd brakelight comes on when the brake pedal is pushed. If so replace the MFS. The 3rd brakelight in late 80's fords bypasses the turnsignal switch.

1987 ford thunderbird brake lights not working

Yes therse a brake light switch activated by the movement of the brake pedal Follow the brake pedal arm up under dash and you will see a small switch.Move pedal in and out to see if the switch is being activated and no wires have fallen off.Yes all three could be burnt out but inlikely,This fault is usualy associated with corroded or poor chassis earth at the bulb holders and if the circuit board type they too will need to be checked Usualy checked with test light/probe to determine if the power is flowing with no resistance and wether the chassis earth is intact and working.Good luck
