I have a problem with my brake lights, they dont go on when i brake, today I changed the 2 lights and now the light wont go on when i brake and it wont go on when i turn on my lights. Headlights still work but back lights wont turn on. Blinker and reverse lights still work.

thank you for your help

 

Check the brake light switch which is attached to the brake pedal at the connection to the brake rod going to the vacuum booster.

 

I checked the brake light switch under the dash next to the brake pedal and i found a little box with prob 6 connections and 2 of them are unplugged a red cable and a blue cable dont know which one goes where but any help in this wouild be appreciated.

 

I am having problems still with my 93 cherokee, now the tail lights do not work and the dashboard light wont go on. My headlights are working fine. Please help.

thank you

 

The brake light switch has four prongs sticking off of it. two are for the brake lights and two are for the cruise control. It makes no diference which two go where. when you touch the brake pedal it moves the switch and the switch makes contact to turn the brake lights on. Check that there is continuity across the prongs of the switch when you touch the pedal.(use a multimeter here) If you have continuity the swich is good and you have to trace for a broken wire.
