95 Chevy lumina car turn signals and break lights keep comming on

The security light is a visual indication that something in the car's antitheft system is failing. In most
GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you
put your key in the ignition, there begins a constant line of communication between your key's security
chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module).
These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending
signals to each other. The security light illuminates when that signal gets broken, even just for a second.
When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode.
The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key.
This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

Hi wodermom26,

Your Lumina APV is a clone of the Pontiac Transport and Oldsmobile APV's which all have identical Heater & A/C controls. The Heater & A/C controls usually wear out mechanically causing no control of temperature. This is a difficult repair and is best made by a dealers ASE Certified Technician. A/C may require re-charging and or possible replacement of the hoses which carry the refrigerant as they become porous and leak. Additionally, the Compressor and its Clutch may possibly require replacement.

The High beams are controlled by pushing the Turn Signal switch forward toward the Instrument panel and have a momentary "Flash to Pass" function by pulling the Turn Signal Lever upward toward the steering wheel and return to Low Beam upon release of the turn signal Lever. If neither function of the Beam selector lights the High Beams it is pssible that the Headlamp bulbs are burned out or open connections in the wiring harnesses. Do you have an owners manual for your Lumina? If so it has information regarding the Multi-Functions of the Turn Signal Lever.

on your brake pedal there is a switch that controls your brake lights over time it comes to lose just enough for the switch won't come in contact with the pedal

All you need is a new brake light switch which is mounted by the brake pedal

Make sure both of the bulbs are good first. But the common problem with these body style lumina is the turn signal switch goes open and does not allow power for the lower break lights to work. The 3rd break light does not get power through the turn signal switch. You can by pass the switch and jump the two wires together and make sure they work before replacing the turn switch. There is a big bulk head connector at the bottom of the steering colume. There are lots of wires in there but you are looking for a white wire and an organ wire that are beside each other. I don't have a schmatic at home to give you the pin locations. But they will be on one of the outside connectors. There are 3 sets of wires coming together into this bulk head.
Hope some of that make since?

make sure you replaced the correct directional light relay, and not the hazard relay. Check all fuses. check grounds at rear lights. If all of the following are good, your lumina would have a faulty multifunction switch.

hello......this sounds like a flasher for sure! it is cheap and easy too replace.....FLASHER is located under driver's side dash.......round shape, with 2-3 wires connected at 90 degree angle to flasher, good luck

does it have a coded key?

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