I've got a question. On my 85 IROC, my fog lights only operate with the low beams. Others have said that theirs will come on with the parking lamps, but mine will not. Was mine modified (My harness looks fine) or did GM change the operation at some point? My GTA's fogs will come on with the parking lamps, and I'd like my IROC to do that as well.

My factory foglamps (on my '86) come on with either the parking lamps or the low beams. They shut off when I hit the high beams. As the original owner, I know that this is the way they came.

Jim,

Your fog lamps are designed to operate with either the park or low beams on. Disconnect the fog lamp relay and probe for 12 volts at the brown wire that connects to terminal 5 on the relay. It should be marked on the relay. You should see 12 volts when the parking lamps are turned on, as well as the headlamps. This step will help in diagnosing if your wiring has been altered.

Thanks guys. Guess I've got another project on the (very long) to-do list.

Hey Jim, The fog lights on my 85 only operate with the low beams too. Seeing as the car is still new at 2,480 original miles, I doubt there's anything wrong with it. Yeah, I know there can be problems on a car of any age or condition but I doubt that it's anything but how GM intended them to work...for 1985 at least.

Cool.

That makes me feel better.

My buddy has a 87 Iroc-z and his fog lights come on with either the low beams or parking lights.

As an original owner of an 85, I can tell you that mine only work with the low beams, also.

There you have it. Another fact about '85's that I did not know. I owned an '86 (bought it new) and the fog lamps work with both parking and low beams.

Jim, if you want to change the way it works, it's simple to do. Let me know if you do.

Thanks for the responses guys. This is pretty much exactly what I wanted to hear.

Willie, I'll let you know if I do decide to change it. I'm going to look at my Helm manual to see what the schematic looks like. I doubt that I'll be fortunate enough to just be able to draw the switch feed from a different wire in the dash. I suspect the fog light switch just feeds a relay that's powered by something from the headlight circuit. I'll find out when I troll the electrical schematics.

Jim,

It's simple to make the change. All you need to do is cut the wire that leads to the #5 connector on the relay. This wire supplies 12 volts with the headlamps on. (The relay is located) on the driver's side inner fenderwell just in front of the fender itself.) Splice into any wire that leads to any of the parking lamps and substitute this wire into the #5 connector. I hesitate to state what color it is for fear that I'll be wrong again!! On my '87, it is brown. This will allow the relay to energize with the parking and headlamps.

Thanks willie!

I've got that warm fuzzy feeling from knowing that we both learned a little bit from my experience.

must be 85's only. my friend has an '85 iroc clone --- but it was done to look 100% legit, and it does, except the insurance company has it listed as a SC. and his fogs are headlight only, whereas my '86 iroc is parking and foglights.

My 86 IROC fog lamps operate even with park lights off. Done it before just to see how much light those weak XXX things put out, not enough to drive by (unless you're doing 5 mph). There may be something wrong with them (poor ground, loose wire, ??) but since I don't need them I haven't spent time on it yet. Sorry, I should have paid more attention. The park lamps must have been on, but due to the fog they didn't appear to be. Tried it this mornin'. No park lights, no fog lights.

My 85 is a sho-nuff real IROC-Z and my insurance company (Travelers) has it listed as a V8 SC. They told me the only listings for 85 Camaros they had were for a V6 or V8 sport coupe, no Z28 at all.

My insurance company didn't even ask me about any of that crap. I told them I had a red 85 Chevrolet and that was it.

My GTA on the other hand, was a totally different fiasco. They wanted to know everything about that car.

my insurance company doesn't care what model of motor, all they care is that it's a Chevrolet Camaro, and they charge up the butt for my car to be insured. so it would be good if I was insuring a IROC rather than my SC. they charge you a ton no matter what.

My '86 Z has the foglights come on with both the parking lights and low beams, off with high beams...

another interesting bit of info, I've noticed some car's lowbeams go off when you turn on the highbeams, others stay on...WTF???My friends '89 is like that...

SlowCamaro88SC

that means their lowbeam lamps high filament is burnt out. on newer cars they are made that way, for the older sealed beam lights, they are made that way.

Hey Jim

My 85 Iroc ,before I change them to after market fog lights would come on with parking lights only, or low beams, or high beams.

I guess I'm different.
