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.
