    I'm not too sure. It's my grandmother's car and she has taken it to this mechanic at least 5 times. I was messing with it last night and it seems like there is a short connected to the brake. I kept tapping the brake pedal and eventually the lights went off. Where is the brake light switch? Is it easy to replace? I can try and do it myself. Thanks for the insight!

    It is on the bracket right above the pedal. It should have a white wire and a orange wire going to it. I'm sure of the white wire but I think the other one is orange on this model. Unplug the switch and see if the lights go out.

Don't listen to it could be combination switch , you could replace that an still not have the lights work . Do the center high mount brake lights work or none of the brake lights ?

My brake light and battery lights came on and stay on.

Oops!There seems to be an electrical problem... Ask someone to check it for you (engineer, mechanic, whoever knows how to do it...). Do not leave it as it is! It can be dangerous!

Brake light not working on one side only

A mechanic would check the socket for power on each circuit and the ground with a test light or meter.

Running lights work but no rear turn signals or brake lights

All three circuits go thru the turn signal switch.
A mechanic would check for voltage there next.

Code 48 appears with the 93 Allante. It says EBTCM modular problem or a Brake pressure modulator, Information center on car says Traction disabled, abs disabled and low brake fluid The red brake light...

Before replacing any expensive parts replace the brake fluid sensor. disconnect the electrical connector. squeeze the two tabs together and push it out slide the new one in and connect the electrical connector, then road test it. This sensor is on the bottom of the brake fluid reservior, you DO NOT have to drain the fluid out
