Question about 2002 Cadillac Escalade

Left rear running light works but right one doesn't

I just replaced the rear running light bulb on my 2002 Escalade but the right side still does not work. Now I know its not a bulb issue I'm wondering if it is a fuse or a harness issue. Are the 2 running lights not connected to the same fuse? If they are, then its definitely a harness issue right?

    Now get a volt/ohm meter and check for 12v in wiring. It also could be a bad ground (most probable cause.)

Left bleaker and break light not working. Turn signal works bleaks faster than right side.


Has the vehicle been in an accident on the left rear side. First check the bulb to be sure it is not defective, trade it out with the side that works properly to test. If the bulb works well then My thought are you may have a shorted wire. The turn signal flasher works by heat build up within the flasher the heat is caused by the load of the bulbs, the load heats the metal spring causing it to open the circuit then as quickly as it cools down the circuit closes again lighting the bulbs.
There is also a possibility of a defect in the turn signal mechanism on the steering column. The turn signal switch on many models does three different things on many models that use the same bulb element / or bulb for brake and turn on rear of vehicle. It controls the circuit for brake light by sending power both left and right side rear when turn signal is in neutral position then when turn signal is in left turn the switch cancels brake light power to left side rear and supplies flasher power to left side while maintaining brake light supply to the right side rear, and so on opposite when the right turn is chosen on turn signal switch. The turn signal indicators on the dash normally run off the same circuit as front turn signal bulb only which is also controlled by turn signal switch. Front has turn signals but no brake light.
I think there is an additional load on the left side rear turn circuit and it could be either a wire that is shorted or the turn signal switch if the same bulb element is used for both functions.
Often times if trailer lighting is connected the flasher will also blink a little faster because of the extra load of additional bulbs.

2002 dodge durango left turn signal works right turn signal does not


have you checked the bulbs front and back. to see if they work, bulb check. then it sounds like you might have a bad signal flasher that only works the left side and not the right side. or if a bulb at the front or the rear gets bright but not the opposite bulb on the same side then you may just have a bad bulb or socket or power to the socket when doing the bulb check.

2004 Honda Pilot, right rear brake light doesn`t work. I know it`s not the light bulb because it works for the turn signal and hazard lights.


Chances are that is the bulb. Its a dual filament bulb. The brake portion of it is burnt out. try swapping it with the left side and see if it works then. If it works, get a new bulb.

I have a 2002 pontiac aztek. My rear right signal/brake lamp does not work. When i signal left, the front and rear left lights flash normally. When i signal right, the front right light flashes normally...


as for the faster flashing thats as simple as a blown bulb, replace the bulb and see if that fixes the problem, it may fix the lot because the other symptoms you mention are a bad connection, if bulb is fine check the connection isnt loose or corroded over. if it is simply file it back to establish better connectivity,

One of my daytime running lights will no turn on. I replaced the bulb and it still does not work. I have an 2002 Escalade.


you have to make sure that you did not touch the tip of the new bulb with your bare skin the oils from your skin will blow the bulb out and it is also possible that you got a bad bulb make sure that all connections are are good as well as tight.

Why would the right rear running light(tail light) constantly burn out. 4 new bulbs in last 4 months, 2002 Jeep Grand Cherokee. No problems with left tail light. Automatic, Air, 4 wheel drive, 200300...


I have a 2002 JGC as well and its the driver side one with mine. I changed the bulb this last time and used bulb lube to cover all the metal. It worked for a mile then went out again but didnt burn out this time. I checked the contacts on the base and noticed there was some rust, scraped off with blade and used more bulb lube on those contacts too, working for now.
