Humidity sensor and wet rugs in the Fiat 500e

Humidity sensor and wet rugs in the Fiat 500e. Many people have problems with moisture in the interior of the Fiat 500e. Some have even wet passenger or driver rugs. Sometimes there is a musty smell inside the Fiat 500e.

Why is moisture control inside the Fiat 500e so important?

The reason is very simple and certain. Electric Fiat 500, like any electronic device, simply does not like water. Condensing moisture can literally flood the PCB with hundreds of drops of water. As you know, water is a great electrical conductor. It also promotes corrosion of connections on PCBs.
In my opinion, moisture is the beginning of the problems with the CTM module, responsible for the Fiat 500e Blue&Me.
But the most important reason is the flap hidden just under the rear seat, leading directly to the inside of the Fiat 500e HV Battery
