My fog lights are acting foggy, Like fog, my fog lights don't come on until they get warm. ??? Options

Anybody have this issue or know how to correct it?

My fog lights do come on. However, I have to drive for about 5-10 minutes before they come on. It's like something has to heat up the connection before they will come on.

I thought there may be a bad wire connection. But if that were the case, they would come on intermittently and at random (when I first start the car, maybe go off at some point, etc.). But they always do come on and stay on, just after the car warms up.

Any idea why this is happening?

The first line simply states that relays do not develop a time delay. Those who think they do are just mistaken. Relays are a simple electro magnetic device that changes a set of contacts from open to closed or closed to open. When the relay fails, it will not operate now or later. Having worked in the electrical/electronics field since 1966, I have never seen a relay develop a time delay. If power is applied and it does not work, it is defective and needs replacing.
If yours is coming on later, that is telling me that there is a bad connection somewhere in that circuit that is keeping the power from the relay until you drive the car for a while. I had one similar and when driving and hitting a bump the wipers and associated electrical devices would quit working. Drove me to drink trying to find out what was wrong. J-13, the fresh air blower relay, was intermittent due to weak contact in the socket for that relay. Cleaning the sockets and the relay prong, and spreading the prongs slightly cured that problem.
The thread I put together was in response to a member who had a melting socket issue and it was being caused by heat build-up due to resistive( bad ) contact of the relay prongs in the socket. Heat is the enemy of electrical circuits. After replacing the socket all worked OK.
Clean and tight electrical connections are a must for good performance.
If you don't have a working knowledge of electricity, I can't explain it to you any better than that.
Hope this explains things a bit better.

But along the lines of a bad connection/ground that eventually "awakens" while driving, you could also suspect that the relay itself is sticking. Eventually going over a bump just right causes it to unstick.

The cure is the same though, clean all connections, sockets, etc first. If the problem still persists, try swapping relays, right Tom?

The thing is, even if I don't hit any bumps, just smooth driving, it will come on eventually. I've even experimented at a stop light. I look at my lights in the reflection of the car in front of me. My fogs will not be on. I'll turn them on and off and maybe they will come on while sitting there. Or a couple of times I've turned my lights off all the way (headlights) then back on with the fogs and they'll come on. It always seems to be a common factor of how long I'm driving the car.

A couple times I'll let it run in the garage. Fog switch is on but no light. Then after a while, turning the switch on and off (or just leaving it on), they will come on just sitting there idling. So there's no bump to make a physical change in the connection. Very odd.

Anyway, if all these black round relays are the same, I'll just swap on known good working one with the fog one to see if that makes a difference. I'll also clean the connections with some 0000 steel wool and alcohol too.

This may be a similar problem....
My right blinker is also acting up (gauge light, not external). If I turn my left blinker on, the light in the gauge works fine. If I turn my right blinker on, the light will blink twice then go off (actual turn signals still blink, I'm just talking about the light in the gauge). Sometimes, it will come on again at random and blink once then go off. But regularly, it will blink twice when I first turn it on then stop blinking.

I think Carol Anne's in my electrical system. (IMG:style_emoticons/default/blink.gif)
