The horn does not sound when the engine gets hot

Friends have peugeot 307 hdi 1.6. The horn does not work when the car's temperature reaches 90 degrees. It sounds like a click, from the horns. When the temperature drops, it starts working again. What could be the problem?

In case it does not work, it can be measured whether there is current in the horn. I think there is a sase problem. You should also check the ground connection.

what an interesting problem is strange.

Problem found friends. They say there is a master, there is a master. I showed it to the master, everyone kept saying brain and brain. No, there is no cost so much trouble. The solution was very simple, interesting, but the horns were broken. Horns changed, the problem is over. The cost is 60 TL. But how?

You got it done cheaply again, there is a problem with me for 2 weeks. I haven't shown it to anybody yet. & nbsp;
