Flickering dashboard lights can be a clear indicator of a potential electrical short circuit. When there is a short circuit within the vehicle's electrical system, it often leads to irregularities in voltage supply. Dashboard lights are sensitive to changes in voltage; therefore, if the electrical circuit supplying them is compromised due to a short, it can cause the lights to flicker or dim unexpectedly. This effect may also be accompanied by other electrical malfunctions in the vehicle, emphasizing the need for a thorough inspection.

Inconsistent engine temperature, delayed braking response, and weak air conditioning output do not directly point to a short circuit in the electrical system. While these issues may indicate other problems within the vehicle, they are not specific symptoms associated with an electrical short.
