I have a problem with my headlights. They will only turn on if turn my high beams on. Why is that?

Now for my second problem. When I pull the headlight **** to the on position the right blinker will come on also. During the day if I try to signal right it shows the green light constantly. it does not blink on the inside or outside. Earlier during the week I fixed my ignition lock cylinder so I probably messed something up. How would I fix that?

Thanks

 

Try checking all of the bulbs and fuses.

 

I checked all the fuses and they were good. I will probably replace all the headlights. But I am still puzled about the blinker???

 

GM's blinkers are wired so that if one of the bulbs burns out or shorts the indicator in the car stays on steady, alerting you to a problem with the lights.

 

OH really, thats odd. Now I have to take the guage cluster out. Thats a pain in the ***. Can you get pulled over or anything if the outside turn signal does not blink? Thanks for your help Morley

 

Why? I was talking about the outside lights, turn signals.

 

wait im confused. So let me get this straight...to fix my blinker problem I have to replace my outside turn signal bulb? Would I also have to replace the bulb for the turn signal in the guage cluster?

 

If it lights up I probably wouldn't replace it.

 

I tested all my blinker lights tonight and the side turn signal does not light up at all so that should be the problem. Would you guys happen to know the size of the bulb that goes in there? Thanks again for your help.

Thats exactly ehat I was talking about, if an outside turn signal or marker light goes out, the dash indicator will come on with lights on and will come on steady with lights off and turn signal selected left or right, it is a "tell tale" to let you know there is a problem on the outside lighting, which you wouldn't otherwise notice.

Same bulb as the interior lights, little press in bulb.

 

the side marker lights are 194 bulbs, and the rear and front lights are 1157 i think

 

If all this started after you worked on your steering column that is a good indication that it is some thing in you your reassembly. Might be a pinched wire for you turn singal switch that travels through the column. Does your 4 way flashers work? Runs off the same circuit and is good for a complete bulb check as well. And the fact that the singal stays on was not a built in check to show you you have a problem it is just how GM wired it. Asked one of my GM teachers that myself.

 

Well, yes they did build it that way, because they opted to wire the system this way. It wasn't an "accident" that it turned out like it did, the electrical engineers knew that by wiring the lighting system like they did it would have that effect. It is also in several GM troubleshooting guides that when a light behaves like his is doing it is most likely a fault with an outside light.

Because they teach a subject doesn't mean they know all.

 

Hey guys, my right side marker light bulb was out so I thought that was causing my problem. I replaced the bulb today but the blinker still does not flash, the light is just constant. When I turn the lights on the right side marker light is lighted up a little bit but when i signal right no light emits from the side marker?

Any help is appreciated.

i dont know if this was suggested but have u checked your flashers? they are in the convience center located under the drivers side lower dash panel

 

No I have not checked the convience center. Is the center easily recognized? How do I know what the flashers are? Sorry if these are dumb questions but I have never checked there before. Thanks.

Mike

 

it is right above the ALDL port on the drivers side lower trim panel, u have to remove that panel, which is i think 3 screw bolts
and when that is removed u are looking for cynlinder looking metal devices which when removed will have 2 prongs on the bottom of them

 

Well my flasher work because they flash inside when i turn the hazard lights on.

 

im not sure if this is right, but also check your grounds. I had a problem where if i turned my int. lights on, both my blinkers would illuminate slightly on the inside and would not flash when i turned them right or left. I simply attatched a ground that i forgot about and voila it worked! like i said i dont know if that is right but im just trying to help you rule out everything so u have a better chance of finding the problem. Hope u figure it out man!

 

There's two different flasher units...one for the hazards, and one for the turn signals. The one for the turn signals is seperate from the convenience center; the original one should be a light blue and will plug into a dark blue plug. It may even be clipped to the side of the metal frame for the convenience center. Just remove the hush panel, and you should see it above where your right leg would be if you were sitting in the seat.
You say the indicator in the cluster comes on with the headlights? Pull your headlights on, and turn the dash lights all the way down and see if the light goes out. Do your tach and oil pressure gauge act funny when the lights are on? If so, you have a bad ground to the cluster, or a break in one of the PC traces on the backside of the cluster.

Hey, Where would I find the ground for the blinkers? I have little knowledge about electronics thanks for the help, I appreciate it.

 

Ok, tommorow I will check the convenience center out. Its too dark right now. Yes, the right turn signal indicator comes on when the headlights are on. When I turn the dash lights all the way down the turn signal indicator is still on. My tach doesnt act funny and I cant tell if my oil pressure guage is because it is shot.

 

Hey, I am having the same problem with my right turn signal coming on with the lights. The car is 88 Iroc. It also makes my tach and oil pressure gaues act funny or quit working when the turn signal is in use. Could I run a new ground to the cluster and where would I connect it to. All my lights are working on front and back of the car. How could one find a bad ground connection on the gauge cluster? Thanks Cleve

 

It most likely is a broken trace on the back of the cluster. You'll need to pull the cluster out and check them over very closely - it could be difficult to spot. Here's some of my handiwork

 

Hey, I am still trying to track down the problem with my Blinker coming on with park lamps. I bought this car with a rod knocking so I didnt drive it untill the motor was rebuilt so I dont know if it was acting up before the rebuild. When the lights are on the guages act werid or quit working. I switched a different gauge cluster in the 88 IROC to one from my 86 IROC and still have the same problem. I also checked the circuit board on the back of the cluster and it looked great on both clusters.I just rebuilt the motor and reinstalled all of the ground straps on the engine. So were else could I look for a bad ground that would effect the cluster. Help I'm going crazy trying to trace this problem down.
