Did you replace the hazard/flasher/blinker relays?- they are in the fuse block usually.

This is weird, but try this: Turn on your hazard lamps and turn your steering wheel all the way left and all the way right.
Then turn on your left blinker and hold the blinker on while you turn all the way left, then right. It will click and try to turn it off but keep it held down and turned on. Then do the right blinker the same way.
I have had this problem with every GM I've ever had, something about the detent-return and the blinker relays getting reset. I'm not sure why it works, but if your flasher relays are good and your fuses,bulbs and wires are good then this is probably what will fix ya. I've had this happen often enough that I always do this first. My GM vehicles were/are all 60s to 90s models- old school, but try this before you do anything else with it it's free and only takes about 15 seconds to do. Sometimes I have to do it more than once, but eventually the detents reset and they work. Viola!
Good luck and please rate this solution if it fixes ya!

It could be the combination switch (turn signal switch). It could be the turn signal flasher. When you turn on the turn signals does the green light on the dash light and not blink? Or the green lights on the dash do not light at all? If the green lights on the dash come on but do not blink it is most likely the turn signal flasher. If nothing lights then check power into and out of the switch. If you have power into and not out of the switch then the switch is bad. If no power into then check fuses and fuse links. Check the fuses under the dash and under the hood. Hope this helps. Good luck.

Need to locate the EBCM on a 1996 tahoe


Your brake light switch circuit also goes through the BLINKER SWITCH. Did you check that? (Most common culprit in GM vehicles.)

Turn signals not blinking


rule 1: check fuses first.
100% sure, , as it is 100% electrical, those lights and radio.
the combo switch is just that with an electric switch.
since the HAz works, that means the wiring and lamps are all good.
so must be a comb switch issue or just a simple loose fuse.
or in some cases the fuse is intermittent.

the FSM , shows the schematics and how to diagnose it.
using only a cheap $10 meter, like you see at walfart.

the auto cancel on most cars are mechanical.

simple or hard,? well who knows, with fate or entropy. but
the air bags need to be defeated working near dash.
the system is very simple, back when.

haz and turn (I'm looking at schematic now)
same blinker flasher, so not that.
same lamps, and wires to same.
but the blinker has its own fuse marked. TURN
the haz has its own switch and FUSE.
the blinker switch is seperate
so......................
so the TURn fuse bad, or loose. (some look good and are NOT)
or the turn combo switch (in hand) is bad. or wires to it loose.
just becareful fiddling near driver air bag, treat it like a shot gun shell.
most the yellow wires are air bags and dont touch them. dont even
flex them, the FSM covers defeating air bags for service.

i will quote toy now.
To avoid personal injury when working on vehicles equipped with an air bag, the negative battery cable must be disconnected and at least 90 seconds must elapse before working on the system. Failure to do so may result in deployment of the air bag. (unquote)

Steering wheel adjustment lever to raise or lower is broken and the turn signal lever on the steering is not working the turn signal lights wont light up so can these lever be replaced or do I replace...


yes they can be replaced , what you are looking for is called a combination switch . it maybe faster and as cheap to find a hole steering wheel at a auto salvage yard. keep in mind that then you would have to change key assembly and ether way use caution with air bag , if there is a chip in your key there is a fuse that has to be removed before disconnecting the battery.then under the dash there will be a yellow wire for the air bag that will have to be disconnected it will be labeled inflatable device caution or warning. if you should want any further help please feel free to ask . Thank you Have a grate day

Blinker issues


These are two seperate issues:

the light staying on solid green indicates a bulb blown at either the front or rear, this could also be a bad ground connection but usually is a bulb issue. If you replace the bulb, be sure to use bulb grease to seal our moisture.

As far as the signal arm returning to neutral and cancelling the signal, that is controlled by a part within the steering wheel itself, and could just be worn. It's a Plastic/Nylon piece that pushes the signal arm manually when you turn the steering wheel sufficiently. That would be a dealer part, or something purchased from a salvage vehicle.

good luck

I got into accident, airbags deployed, dont want new airbags, but front blinkers dont work, how do i fix?


If this was a reportable accident, your insurance company should take care of the air bag and consequencial damages. Bypassing safety devices as such creates greater risk of severe injury because the rest of the vehicle is designed with all systems functional. Ck w/ insurance co.
