    Default Mehran auto radiator fan problems

    I have recently noticed that my mehran's radiator fan is losing its speed. It is currently on auto. Switches on when the car reaches optimum temperature and then switches off. I had showed it to several electricians. All had convinced me that the wiring has weakened. There is nothing wrong with the motor. For my satisfaction they had also connected the fan directly to the battery and then the speed was remarkably better. Now they are suggesting to install a relay for improving the fan speed. But all of them have warned that the auto switch will not work. Once the relay is installed, the fan will work throughout even in cold engine. Expertz please help. Is it possible that the auto system works even after the relay is installed???

    in hot summer, the fan & heat related problems are very Common. so don't worry much.

    Well, i will never suggest to put fan in the direct mode in any case. 90% mechanics suggest to do so, but this is wrong. Experts like Xulfiqar bhai have repeatedly mentioned in his posts.

    Have you tried to replace the whole fan ?
    if it works, then have it replaced. Its not very expensive.

    Seems that fan motor has got weaker. so instead of replacing motor, its better to replace the whole fan (including motor). You can purchase it as new or in 2nd hand as well (if the condition is good).

    I'm taking summer school to repeat my Electricity and Magnetism course. Electrical systems are not exactly my forte .

    Just taking a guess here: the fan is not properly grounded, probably due to loose wires, or the wires have developed a high resistance.

    the fan is fine. its just the weak wiring that is slowing it down. I am asking that if i place a relay in the system, will the auto system work or will the fan be direct?????????? electricians say that relay and auto switch do not work together! I want my system to remain on auto even if the relay is installed
