The fan works but not normal. Just like the other day, I tried to switch-on the aircon and the fan did not start right away. I tried to tap fan frame with the handle of a screw driver several times until it slowly turns. I kept on tapping the frame until it runs at normal speed. Is the function of the relay is just to switch on and off the fan motor when the engine temperature rises at certain level that is set to activate? If the relay function is just to switch it ON and OFF, the rotation should be immediately at full speed upon start up. However, I observed occurrence of slow and won't start immediately. Can we conclude its the fan motor that is defective or the relay?
