Replace turn signal switch 1998 chevy lumina

See if bulbs have burnt out in the left brake light and rear turn signal (one bulb if combined) and also rear center high mount brake light.

If the left turn signal has a slower speed than the right turn signal, this is a symptom of a bulb or bulbs burnt out.

Usually, the wiring is not a problem, but I would not rule wiring (or sockets) as a problem out.

Good luck on this repair.

Check the turn signal switch. especially if the center brake is the only brake light that comes on when you step on the brake pedal. Sometimes wiggling the switch will get the brake lights to work momentarily.

In a Lumina if the brake lights quit working but the upper one in the rear window still works or your tun signals flash weakly or a different speeds the turn signal switch needs replaced. I will cure the problem. Not to hard a job, but does require removing the steering wheel and air bag assembly.

The brake light in the rear window and the main brake lights are on a different circuit. After the signal leaves the activating switch on the brake pedal arm, it splits. One circuit goes straight to the high mount brake light, the other goes into the turn signal switch. If the rear turn signals work but the brake lights don't, suspect the turn signal switch, not the bulbs and wires. Better to check this before removing and checking bulbs, wires and fuses. It is a common problem with the W-body cars like Lumina, Monte Carlo, Buick Regal, Olds Cutlass and Pontiac Grand Prix. (Approx 94-99 models). Part number is GM 190005031 (w/o radio accessory control) or 19005032 (with radio controls)

have you tried the brake light switch? it is mounted on the brake pedal and when you press the pedal down it makes contact to power brake lights and turn signal switch

why not just replace the turn signal switch must faster and safer . buy one from your local parts house then you can see its not that easy to install but you can do it with a little help

Had the same issue in the spring. Replace the turn signal switch. A general weakness in the switch in these years. Replacement solved the problem in my 97 Lumina.

this would be a multifunction switch which turn signal switch wipers ect. run through located on steering column under plastic cover.assuming the brake light switch is good see if third brake light works when you press the pedal if so it is deffintly the multi switch.

This is a classic example of turn signal switch failure. On GM vehicles with a multi-function turn signal switch and combination stop/turn/tail lights (all rear lights are behind red colored lenses except for back-up lights) The brake light power is routed through the turn signal switch. This makes it possible for the right rear light to function as a stop light while the left rear turn signal flashes, and vice-versa. When the contacts fail to remain constant the brake lights, and turn signals can become intermittent. The proof that the brake light switch is functioning correctly is that the high center (cyclops) brake light functions properly. Wiring integrity is verified if you can prove that turn signals operate, but that can still be intermittent with this complaint, BUT if you use your hazard switch to turn on all the signals at once, you can verify wiring integrity. This is because the turn signal, and the brake light use the same circuit, and bulb filament in the rear lighting assembly. If any Hazard lights fail to function, check bulbs first, then retest. If all Hazrd light flash correctly and reliably, bulbs, sockets, and wiring have proven integrity, and the turn signal switch is the remaining component in the system which needs to be tested. Unfortunately, this switch requires disassembly of the steering column for service, testing or replacement. If you have never disassembled, and successfully reassembled a GM tilt steering column, I would reccommend professional assistance.

i would check the bulbs first. then continue to the brake switch
