2004 jeep grand cherokee, when I put the lights on and apply the brakes, all the lights on the driver's side rear go out except the blinker light will work. Brake light still works when lights are not on though.

will u have a few more switches and relays to check/change brake light switch and relay/and headlight switch

check for chauffed wiring under dash around steering column and brake pedal, as for your rear brake/side light you have probably put the bulb in the wrong position remove bulb and rotate and retry

Check brake light switch on the pedal . It may need an adjustment.

IT WAS THE TAIL LIGHT BULB

THANKS

I would suggest that you take a look here (I used this to correct brake-light issues on my '01):

Many Grand Cherokees have had this type of issue. The thread is lengthy, but does cover just about every type of issue known with the tail/brake lights.

Open up the hatch and look for the screws that hold the tail light assembly to the body. After removing them you can gently pull the whole tail light from the truck. You will seee the sockets that the bulbs are in and they twist like a bottle cap to get to the bulb. Just pull the bulb from the socket and reverse what you did to put it back together.

If you are sure it is not corrosion at the bulb sockets then it could be the back-up switch at the transmission.

First thing to do is chk. the fuse for break lights, if thats ok, than i would say its the break light switch. As far as the right taillight, that could be as simple as a bad bulb.

hmm interesting have you done any wiring to the lights at all?

rear lamp failure. did you check brake and taillight and try blinkers some of the bulbs are dual filament bulbs one filament could be bad. the console light prob could be a blown fuse.
