When I put the brakes on the right side break light goes off what could be the problem

Have you checked the fuses ? If you got power there, then begin checking wiring for damage, breaks or shorted.

Not real sure. If there's nothing wrong with your brakes or your emergency brake then I would probably say it something electrical.

you have an e-brake switch shorted to ground the only light that goes on is the brake light on the dash when you engage the e-brake. check for fryed wires near the e-brake pedel and lever assy.

Changed any bulbs in the back latley? if so I surspect so see that they are the correct type in the correct holder if you put a single base bulb in a double base holder.. Double base in holder one side is brake light the outher is the side lights, the single base shorts them together...so when you brake,the brake lights start supplying the side lights... So it lights your dash lights as well look in frount of the car while some one breakes for you and I bet the front side lights com on on their own!
and thats why!! VERY COMMERN MESTAKE!
O.K.?

The wire is white and starts at the switch on the break peddle and goes in the body harness on the driver side of the van and goes all the way to the back where it splits for the top break light and both break lights in the back.

If you are not getting any voltage in the back I would check right at the break peddle switch and go from there. Good luck

to do a complete job. you need to bleed all 4 wheels, starting from Right Rear. Right front. Left Rear. Left Front.

I had the same problem. They were on when the headlights were on, but turned off instead of brightening when I pressed the brake. I replaced the bulb and now it gets bright when I press the brake instead of turning off (like it should).

thereis three switches to check one is the muti function switch. the second is the headlight switch and third is the brake switch on the pedal.if not them check your ground and see if it is secured properly

hello zeeko1 , over here when that happens its because someone put a single element bulb where a double element bulb goes , now this bulb you take out to fix the problem , look at the bottom of the socket see if it has 1 contact point , then look into the hole where the bulb goes , i bet you see 2 contacts , this single contact bulb is shorting out into the other circuit back feeding voltage to other circuit . cheers mate !

Thanks for using FIX YA !

Make sure that your hazard switch is all the way OFF I have seen this problem. But here power comes in the brake light switch from the fuse, when you press on the brake it closes and powers the other wire that goes up into the steering column into the turn signal switch and then out to the brake lights I can send you a wiring diagram if you send me your email to [email protected]
