Fan turns on but turn off right away? Help?
so I just recently flushed my coolant and changed my thermostat thinkin that would fix it but i recently found out that the fan doesn't really work. It would turn on for a few seconds when the car starts to overheat and it will turn off. So im 100% sure that the fan is the only problem... anyone have had this problem and fixed it? i would appreciate it if someone helped me... THANKS!

If the 1.6 sensor has been transplanted to the 1.8 motor, it is probably still driving the fan relay. The relay could be faulty or one of the connections could be loose. When the car is up to temperature high enough to activate the fans, the unit on the thermostat should short to ground. Take the connector off and short the wire to ground. If the fans stay on, it is a bad sensor. If the fans react the same way, check the relay and connections.

so earlier today i was checking the connector and wired it to ground and nothing happened.. i know the fan still works because i turned on the ac and both fans turn on.. what could be the problem? what to do from here. just to make sure im suppose to wire it to ground right?
