What are the reasons for the difficulty in pressing the Cadillac CT5 horn?

The reasons for the difficulty in pressing the Cadillac CT5 horn are as follows: Contact point erosion: If the horn is pressed for a long time, it can easily cause the horn contacts to erode and create impedance. This reduces the current flowing through the electromagnetic coil, decreasing the electromagnetic attraction force and preventing it from attracting the armature to drive the diaphragm to vibrate normally. This results in a hoarse sound or even no sound at all. However, when the horn is pressed continuously, if a strong instantaneous current passes through the impedance, it can still function normally, leading to intermittent performance. Poor sealing leading to moisture: Although the horn is internally sealed, if the sealing is not tight, moisture can enter during car washing or water vapor may be present in the internal air space. This moisture can easily cause the contacts to become damp and fail to work properly. Poor contact at the electromagnetic coil terminal: Some horns have aluminum metal rivet crimp connections for the enameled wire terminals of the internal electromagnetic coil, rather than secure soldered connections. If the insulation paint on the enameled wire ends is not completely removed or the rivet crimping is not secure, it can easily lead to a faulty connection, causing the horn to malfunction. This type of fault is due to the quality of the horn and cannot be repaired; only replacement with a new part is possible.
