the fuse is labled 'brake'
I would replace the fuse... and then have someone stand to the rear of the vehicle and watch the lights come on as I applied the brake... if the fuse blows again... note which tail light did NOT come on durring this test and replace the bulb.. it is grounding to itself and causing the short.
While not likely, it is possible that the light bulbs in both sides are have bad filaments. Turn on ignition key (but don't start engine). Then turn on parking lamps (first detent or "click" on headlamp switch). Walk around car and look for illumination on front parking lamps and rear tail lights. Turn on the right turn signal. Are those (right hand) lamps now changing brilliance? Try the left turn signal in the same manner. Are those (left hand) front and rear lights changing briiliance? Take note of any positions that did NOT change briliance when the turn signals were activated. If NONE changed briliance, you either have a bunch of bad bulbs (unlikely) or a bad flasher (more likely) or a bad turn signal switch (most likely) or perhaps wiring problems (possible if the car has been in a collision or has been "worked on" by some "non-expert" mechanic). Check the action of the emergency flasher control switch located on the steering column (facing up). Pushing it in (down) should result in the button going to two different heights alternately (low, high, low, high). You could just have bad flashers or corroded flasher contacts! Good luck!
The location of the flasher relay on a 1998 Dodge Truck is in the fuse panel which is located on the left side of the dash. It is accessable when the door is open. All you need to do is pull off the panel cover to expose the fuses, and the diagram on the fuse cover will show you which one is the falsh relay. The one on my truck is blue, and is about one inch square.
Hope that helps.
i would replace the brake light swtich first its more likly too go bad than the turn signal switch
Just found the answer on another site. Sure enough went out removed the 3 philips head screws in the steering column opened it up and walla a wire connection had pulled itself free. When my son uses my truck he always uses the tilt steering, when I get in I have to readjust it. because of this the wire connection pulled itself out. I simply pushed it back in an blinker and brake light are now working. My husband is now trying to figure a way to secure the wire connection so it doesn't pull itself out again. Hope this helps others, either by saving the cost of a dealership or machanic or from getting rear ended.
