Question about 2005 Chevrolet Colorado

1 Answer

Blinkers, highbeams, autolights and other circuts

So I think I have a bad bcm or maybe its the multifunction switch but im leaning towards the first. I drive a 2005 chevy colorado standard shift. The blinkers work sometimes as with the hazards. the hazards always work if the engine is off... the electric ports seem to work sometimes but always when the engine is off. the lights behind the air conditioning controls light up dimmly when i shut off the engine until i open the door some amount of time. (but not at all when engine is running) the highbeams work when the engine is off or when the lever is pulled towards me. interestingly this also makes the blinkers work. the automatic headlights stopped working when i discovered this. i can also make the blinkers work by turning the lamp nob all the way to the left but this turns of my low beams. and no matter wich way i flick the lever after doing this it blinks left until i turn on the parking lights or low beams. also sometimes when i flick the lever so that the right blinker should come on the left one does instead. also (seemingly unrelated) im throwing codes for both o2 sensors.

YOU MIGHT WANT TO CHECK THE BULBS IN THE REAR LIGHTS THEY OFTEN STOP WORKING IF THERE IS A BURNT ONE . IF NOT THEN CHECK TO SEE IF YOU CAN HEAR THE CLICK WHEN YOU ENGAGE YOUR SIGNAL EACH WAY IT MIGHT BE IN THE STEERING COLOUM WHERE IT CONNECTS TO THE SIGNAL ARM

SOURCE: need wiring diagram for headligt on 2003 chevy impala with 3.8 cu engine

Sounds like a short or the relay is going bad to the headlamps. You may be able to google for the diagram but probably will need to get a repair manual from the nearby auto parts store for appx $25.00. I would start by checking continuity with the battery disconnected on that side from the positive wire to a ground. Also start with checking the relay, they are usually generic and you should be able to swap two as long as the numbers match and see if that fixes the issue.

Where is the blinker relay in my 2011 Chevy Equinox.


PCB Relays
This vehicle is equipped with the following printed circuit board PCB mounted relays.
• High beam
• Low beam
• DRL
• Fog lamp
• Park lamp
• Stop lamp
• Horn relay
They are directly soldered to the underhood fuseblock circuit board. A failure of one of these relays will require the whole under hood fuse block to be replaced.

Turn Signal/Hazard Lamps
The body control module (BCM) is responsible for controlling the turn signals and hazard lamps. When the turn signal switch is placed in either the left turn or right turn position, the BCM receives a signal from the turn signal switch. The BCM then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, the BCM receives a signal from the hazard switch. The BCM then will send an on-off voltage signal to all the turn signal lamps. All the turn signal lamps will flash including both IPC turn signal indicators.

Vehicles are just not the same as they use to be. Electronics !!!!!

Short in electrical system?


when the radio is OFF sound comes out of the rear speakers when the blinkers are used ! There isn't a turn signal flasher on your vehicle ,( like most all newer vehicles ) It's done electroniclly by a control module . In the case of your vehicle , the BCM - body control module . It doesn't matter if the radio is off . All the Audible warnings come out of the radio speakers . Headlamps left on , key in ignition etc... You have no idea of the complexity of your vehicle , it's a rolling computer , with a serial data network for the modules to talk to each other , share info.
When the turn signal switch is placed in either the left or right position, a ground signal is completed from the turn signal switch to the BCM. When the hazard flasher switch is activated, a ground signal is completed from the turn signal/hazard switch to the BCM. The BCM then sends an ON-OFF voltage signal through the fuses to the appropriate turn signal and side repeater (export only) lamps or to all of the turn signal fuses for hazard operation.
Really don't think you have electrical short . Computer glitch maybe , radio problem . How ever , these system's are not for the untrained to mess with . Your best bet , the GMC dealer !

Highbeams work, low beams do not. wipers only work when highbeams are on. highbeams work but only when you HOLD the turn signal lever towards the steering wheel. all other lights work. relay switch or...


The problem is most likely your cars multi function switch. That is the switch that controls your blinkers, dimmer, and everything else. If you change the switch that should solve your problem.

Headlights go out


If your Highbeam Switch is on your streering colum (turn signal lever) Thats where I would start too look! It could be the wires to the highbeam switch. I had that happen on my ford. But if the highbeam switch is on the floor, check for a bad circut connection and if that checks ok it might be your main headlight switch! Even though you may not loose your highbeams, your main headlight power still runs through that highbeam switch, and being on the colum thats why the would start to function when you move the shifter.

Turn signals don't work at all


Well if it isnt the fuse or the blinker relays then it is gonna be the multifunctional switch. This controls your headlights, blinkers, hazards, cruise control, and wipers. To find out if this is bad turn the if=gnition on and turn a blinker on then depress your hazard switch, if the start to flash then the switch is bad and needs replaced. About 150 at a parts store. And the blinker relays are located under the drivers side dash. One on either side of the steering column. Look for a little silver round relay that is about 2 inch in diameter...should day 552 on it. The hard to reach one is on the right side of the column and is towards the back tucked in a little.

I need the name of the actual switch on the wheel


You knew the name of it, it's in your question, highbeam switch! Ahhh... the good old days... the highbeam switch was foot operated, remove 2 screws, unplug wire, that was all there was to fixing it.
