Hello, i broke the emergency light switch off on my 1996 chevy s10 and now the emergency lights will not turn off. how do i fix the switch?

You will need to take the steering column apart to replace the switches. You will need specific tools to do it also.

bad multi-function switch

Hello: There are two things that could be dausing this: One is the board that holds the bulbs in the tail light assembly, it could be shorted internally. The other thing is on the rear right fender on the inside there is a electrical distribution box for the rear lights it also could be internally shorted, also the connectors to that box could be corroded and causing your problem. Hope this helps.

Your emergency break has a cable. I would say the cable is broke, in the lock position. I don't know the specifics, but the cable is probably broke.

check voltage from brake switch to signal light switch, signal goes from brake pedal to signal switch then to taillights, i suspect the problem is in that area

you need to check the "combination turn signal/hazard flasher/daytime running lights module"
it is located in the junction block,the junction block is adjacent to and left of the steering column,you need to remove the lower dash panel below the steering column,then remove the steel knee brace.

It is either your hand brakes have gone bad or the brake system has gone faulty.

have a thorough check at these.

Cheers

Try checking the headlight switch it may have broken contacts in it. Easy fix go to a salvage yard find same make and model truck, swap headlight switches.

If the problem is that the brake lights will not turn off, the problem is most likely the CHMSL relay. An easy check is to take the cover off the fuse block mounted on the driver's side fender well and swap the fog lamp relay with the CHMSL relay. If that fixes it, just get a new relay for the fog lamps and you're good to go. Note, my 2002 s10 does not have fog lamps, but it still had the relay populated in the fuse block.
