Brake light bulb socket on 2006 Ford Escape was shorting fuses due to moisture...try some bulb grease. Worked for awhile but then started again. Going to try replacing the sockets next. If it is the socket, there should be some discoloration around the edges due to the shorting.

Ok..........take a really good look at the connection point of your bulb socket. There must be a short in the wiring at or near that point. You can further brak down the location by having someone step on the break and you check to see if there is actually current going to the bulb socket ( without the bulb in of course) Really give it a good going over , shorts are difficult to find some times. Good luck, RC

When the body control module (BCM) receives a signal requesting to illuminate the backup lamps, battery voltage is sent directly from the BCM through the backup lamp supply voltage circuit to the backup lamps.
Voltage for the backup lamp supply voltage circuit as well as the courtesy lamp supply voltage circuit is from the left instrument panel fuse block TBC 2B 15-amp fuse directly through the BCM to these circuits.

Brack lights wont light up on my 1988 ford ranger we keep blowing fuse and put in new brake switch


If you keep blowing the brake fuse than you have a short in the system. Unplug the brake switch. Install a new fuse. If it did not blow than the problem is after the brake switch. Next unplug the turn signal switch, then plug the stop light switch back in and press the brake pedal. Did the fuse blow. If not than the wiring is good in between the two switches. With the turn signal switch disconnected use a jumper wire in between the light green wire (power from the brake switch) and the orange with light blue wire (power to the right brake lamp). If the fuse blows than there is a short in the right side brake circuit between the plug in and the rear socket assembly. If the fuse does not blow than jump from the light green wire to the Light green with orange wire (power to the left brake lamp). If the fuse blows than the problem is in the left hand brake wiring circuit.

Is there a fuse or relay or micro relay for the CHMSL on 98 sts


check the lt blue wire at upper lamp,(under trunk lid trim panel) for 12 volts when brake is applied. if no voltage,check same color wire at brake lamp switch for voltage.(by brake pedal).if no voltage replace stop lamp switch asm. if voltage is detected at rear by lamp then replace CHMSL asm.(center high mount stop lamp). this lamp is made of many LED's,if some work and some don't you will need to replace lamp asm. can be repaired by a trained GM tech, possibly. there is no seperate fuse or relay for this lamp,only a stop lamp fuse.

Fuse problems on hyundia lantra 1999


are the rear lights combined? ie sidelamp and brake lamp in one bulb .if so, there is a possibility that the bulb is not sitting correctly in the holder , causing both the side & brake lamp fuses to blow . if they are seperate bulbs you probably have ashort in the sidelamp system somewhere but the brakes could be a switch problem [easy check, find switch ,disconnect wires short across using wire or paperclip switch on ignition and check lights ] if they work the switch is the problem , [check fuse first] if they don't
