1) Replaced thermostat
2) Replaced fan switch
3) Changed the relay (swopped with another) and checked fuse.
4) Ran the fan directly from the battery and it works
But the fine just does not kick in at all whne engine is hot. Please help !!
i have a 95 civic and have replaced the radiator fan motor, the thermostat, and the relay switch, the issue keeps going on the fan wont turn on but i did notice when i replcaed the relay switch the fan powerd on no hassles and now doesnt any longer.. i havent checked the fuse inside yet but i will and might check if the relay switch still works..
Hi. Check the bottom of the radiator or on the side, as you also have a temperature-sending switch. The switch must reach a certain temperature before sending a signal on to the fan relay.
The switch just screws into the radiator.
If you would like to contact me again about this or other problems, feel free to do so.

Javier23, I see you replaced the fan switch, I believe you need to replace the 'cooling fan control'. This reads the coolant temp and passes info to the engine control computer, which signals the cooling fan switch to cycle on and off. It seems to be the only missing piece of the puzzle. Let me know how u make out.
If your heater is not heating your vehicle adequately, it could be the result of a few different things:
1) Your thermostat could be stuck in an open position. This will result in your vehicle being underheated. Typically, a thermostat opens only when an engine reaches a certain operating temperature. If a thermostat is stuck in the open position, radiator coolant flows into an engine before it reaches normal operating temperature. This prevents adequate engine warming and results in engine underheating. DIY repair costs: $5-$10
2) Your radiator could be low on coolant. If this is found to be the cause, then you will have to inspect your coolant system for leaks. Depending upon what type of leak your vehicle has (if this is found to be the case), I would have this repair done by a shop unless it is something reasonable simple to fix like a water pump leaking. A replacment water pump will run you $70-$100.
3) It could also be a defective switch.
Good Luck!
