Question about 2003 Isuzu Ascender

2 Answers

Rear Brake lights and rear parking lights are not working. 3rd brake light is ok. I checked the mini fuses and all are good. What else do I look at?

When I step on brakes just the 3rd brake light comes on. I turn on the parking lights or the head lights and still no lights in the rear. Turn signals are good. So far I checked the mini fuses for the rear lights and they are good. Any solutions ? Thank you.

When cling fuses are you using a test light? If so you could be getting feedback on one leg of the fuse pull the suspect fuses and visually look at fuses or ohm the fuse legs ck for power and ground at the taillight socket or a faulty relay if equipped good luck

SOURCE: brake lights go out when head lights are on

Most likely a bad earth to the light's. Re-earth the tail lights should sort the problem.

No brake lights


Look under the dash, on the brake pedal arm. There are one or two switches that activate brake lights and/or shift unlock. Check for loose mounting nut or a missing rubber nubber. Is the brake pedal coming all the way back up? Look on the floor for something not usually found there. These switches are adjustable and it may be as simple as adjusting them. Have a helper look for brake lights on and shift lever unlocked while you push and release the switches with your finger. Depress the brake pedal to get it out of the way. Remember to set the park brake first. Could just be a bad switch or loose connector. Check fuses and the bulbs. Is shifter fully in Park? Also try jiggling the turn signal lever.

The power flow for the brake lights goes like this: Fuse ->Brake switch -> Turn signal switch -> Rear lights. The only difference is, if you have a 3rd brake light in your rear window, that gets its power directly from the brake switch. It does not go thru the signal switch first. So, if you are having a brake light problem, and your fuses are good, check the 3rd light in the rear window, if it lights up (assuming the bulbs are good, no one ever changes them), then the problem is most likely in the turn signal switch, hope this helps!

My additional brake light is not working i have tested the brake unit and that works is there a seperate fuse for this or is it all on one fuse for all the brake lights


The third or High Mounted Brake Light runs straight off the brake light switch on the brake pedal arm. You say you tested the "brake unit"? I assume you mean the third brake light assembly, and if you get power there when someone steps on the brake pedal, then the bulbs are bad.

All this stuff runs thru the multi-function stalk. (the turn signal lever) It could be worn out.

My 2003 Pontiac Vibe tail lights do not work. The brake lights work. I checked the tail fuse. Turn signals work also. Why no tail lights?


Your turn signal lights and brake lights are the same lights . Question : do the front parking lights work ? The front and rear running lights or parking lights are all on the same circuit and fuse . If the front lights work , and the rear lights don't , make sure the bulbs are good first . If OK , I would suspect the problem is either a bad ground in the rear taillight wiring harness or a bad connection in the rear taillight connector Itself .

No brake lights but 3rd light works all fuses are good


Sounds like a broken wire somewhere.
Since the middle brake light works I would suspect it is somewhere in the trunk or close to the back seat.
Buy or make a tester. A 12v light with a clip on one wire that you clip to a good ground on the car the other wire with a sharp point. Turn the turn signals on then poke wire to rear lights until tester lights. When tester lights you know the break is somewhere inbetween the tester and the brake lights.

Hope this helps.

Brake lights wnt wrk when pushing dwn brake, but park lights do


As cadman mention to check the fuse, and if there ok check your brake light switch along the brake peddle arm. Before you doany of that, turn your hazard light on to make sure that all your light's are not burnt out. Good luck

Left rear brake light stopped working but bulb and fuses are OK.


These are Dual Function Bulbs. They control the Parking Lights and the Brake Lights. This Bulb is Burnt out on the Brake Coil inside the Bulb. I have actually seen Bulbs that were Bad But you could not Tell by jast looking at them. It should be fine with a New Bulb. Please Rate My Response! Thanks!
