Answer:
Both technicians are right
Explanation:
It is known that the vehicle's engine temperature gauge is reading higher than normal and the radiator fan does not operate.
The higher temperature readings suggests that the radiator fan is not working due to its motor not being operating. This is confirmed by the technician A since he checked the continuity of the fan motor and it was discontinued.
On the other hand, Technician B suggests that the fuse of the radiator fan might be open which may have caused the discontinuity of the fan motor.
Both problems point out towards the same result. Therefore, both technicians are right.
