These days cars, especially German cars, have a lot of brains inside a vehicle in the form of modules. They are generally called comfort modules or body control modules.

The electric system must be shut down and windows must be rolled down as these sprays are a fire hazard.

If the internal circuit of the car radio has an internal shot, then it can be repaired very easily.
