My tail/brake lights won't turn off. What can I check before I bring it into a mechanic?
SOURCE: Problems with brake lights on my 2000 Jeep Grand Cherokee
YES -- process of elimination. Obviously there's a short circuit in the Brake/Headlight circuits - right? Blown fuse(s) is/are evident of this -- would you agree? Which fuse(s) is/are blowing? An analysis tells you that the only time a fuse blows is when the headlamps are turned on -- correct? Otherwise, brake lights work normally -- right? OK. Head lamps have relays which turn them on. Here's a wiring diagram of the 2000 Hyundai Sonata (NOT the Jeep Grand Cherokee)
It would appear the problem is with one or more bulbs or sockets or both. As you many notice, there are no connections between the headlamps and brake lamps except the parking lamps (which share the bulbs/sockets)
When the headlamps are turned on, so does the tail lamp relay. As you can see, these bulbs/sockets are 'DUAL' filament to ground (series-parallel circuit). Just a guess here - the short is in one of the lower rear brake/parking lamp bulbs/sockets.... just a guess.
SOURCE: no tail rnning lights-brake and backup works-wire
It may not be a fuse at all it sounds from the description (14a) it is a 14 gauge fusible link which is a wire that will burn out like a fuse, check for 12 volts with a multimeter or test light from the fuse box and then continue down the circuit until you cannot find power. Just before this point you should be able to see a part of the wire that looks different and that should be the fusible link.
SOURCE: brake lights don't work
This sounds like a bad brake light switch, this switch is located on the bracket that holds brake pedal,you can test for power at switch,also if you remove connector and jump terminals with a wire and see if lights lite, if lights light then switch is bad,
Turn signal tail lights and BRAKE LIGHTS NOT WORKING
It
can be faulty brake light switch causing the problem or its blown brake light bulb.
First check and confirm brake light lamp is working and that's not
the case.
For turn signal not working it can be faulty turn signal switch or its issue with wiring:----
