My Suburban doesn't have bulbs...they are LED lights. Newer models have bulbs.
If your fuse inside the drivers' side panel is ok, your lights probably have to be
replaced if it's not in the wiring. I checked at the dealership today...a wonderful
258.00! So, to answer your question, mine doesn't have bulbs...
I would guess that both of your brake light bulbs are burned out, and only the high mount bulbs are still working.
There could be a separate fuse for the lower brake lights , or maybe both lower brake light bulbs are burned out
wrong bulbs or bad earth
first check brake light fuse second check light bulbs,they should be double element third check the brake light switch located on the brake pedal
the screws come off and you replace it
I assume you only need to change the bulbs. Go into the trunk and look up. You should see the wires leading to the mounting point for the third brake light, you candisconnect the connectors and then change the bulbs this way.
Remove the two screws that hold the lens on, remove the lens and change the bulbs.
I hate to ask , but did you check the bulbs ? The tail light portion may work fine , but the brake lights don't if both of the bulbs are bad .
I have an 87 Aero Coupe and my 3rd brake light bulb is in my truck. I think yours would be the same too.
If you have the 3rd light working, then you already have a brake signal going to the back of your van. This eliminates the fuse & switch. I would check the bulbs again. I've seen bad bulbs that looked good. make sure the bulbs are correct for the vehicle.. make sure they are installed correctly.
Your hazard/turn/cruise module in the steering column has failed. The third light still works because the third brake light switch is mechanical tied to the pedal.
No. If it was factory installed and still visible on your car, then the bulbs inside must light up.
