2002 JEEP GRAND CHEROKEE LIMITED H.O.
If the head lights are off and I step on the brakes, the brake lights come
on... But the left light is dimmer than the right. When the head lights are
on and I step on th brakes the brake lights come on accept for the left one
goes completely out.
Anyone. Please help.
Thanks, Harold

That usually means the bulb has gone bad. When the brake light filament
goes bad, the parts can fail in a way that hitting the brakes lights up
the running light instead.
Or the fixture has lost it's ground which is usually through one or more
of the fixture bolts, but I am not sure on the GC, and the brake light
is stealing ground through the running light's harness ground.
Going all the way out when the headlights are on implies the bad bulb
though.

Re: 2002 JEEP GRAND CHEROKEE LIMITED H.O.
Hi Mike,
Thanks for your response.
First thing I did was change the bulb.
The issue is that when the headlights are on the running lights work... But
then when I press the brakes all the lights work accept the whole left side
goes out, including the running light.
Im not sure but I think it all started after a recent car wash, although the
fixture itself was dry inside when I changed the bulb.

Re: 2002 JEEP GRAND CHEROKEE LIMITED H.O.
That would imply the ground then.
The brake light grounds through the fixture or it can backfeed through
the running light filament to ground on it's harness connection if the
ground gets lost. This lights up the running light on one side and the
brake light on the other with the headlights off. With the headlights
on, the power then tries to go the other way or the brake light shorts
out the running light so they go off.
I do not know where the brake light ground tag is on the GC. It might
be a copper strap coming from the fixture to sandwich between it and
the/a bolt that mounts the light.
I test this by running a booster cable from the battery negative to the
rear and then jumping a wire to the side case of the bulb to see if it
starts working. If so I clean the ground.

The brake light grounds through the fixture or it can backfeed through
the running light filament to ground on it's harness connection if the
ground gets lost. This lights up the running light on one side and the
brake light on the other with the headlights off. With the headlights
on, the power then tries to go the other way or the brake light shorts
out the running light so they go off.
I do not know where the brake light ground tag is on the GC. It might
be a copper strap coming from the fixture to sandwich between it and
the/a bolt that mounts the light.
I test this by running a booster cable from the battery negative to the
rear and then jumping a wire to the side case of the bulb to see if it
starts working. If so I clean the ground.

That would imply the ground then.
The brake light grounds through the fixture or it can backfeed through
the running light filament to ground on it's harness connection if the
ground gets lost. This lights up the running light on one side and the
brake light on the other with the headlights off. With the headlights
on, the power then tries to go the other way or the brake light shorts
out the running light so they go off.
I do not know where the brake light ground tag is on the GC. It might
be a copper strap coming from the fixture to sandwich between it and
