Since you have replaced the relay and fan switches, does the fan come on with high engine temperature? If not, this fan must run with engine temperature or the engine will overheat. If so then check the radiator for clogs, and the thermostat. Start the engine and run until normal temperature, feel the radiator carefully by hand, it should be hot at the top and generally get cooler as you feel toward the bottom, without any cold spots. If you find a cold spot then the radiator is plugged and needs to be cleaned or replaced. The thermostat is located at the left end of the cylinder head, underneath the ignition module on the 1.9L, it could be stuck closed, a good method of checking this it to feel the upper radiator hose while the engine is warming up, it should become very hot as the engine runs, so be careful not to burn your hands. If it stays cold until the engine is overheated then it is stuck closed. Also check the exhaust pipe, with antifreeze in the cooling system there should be no white smoke coming out while engine is running, if there is the cylinder head gasket may be blown, this will require more intense repair and should be taken to a shop. Hope this helps, let me know.

    I had this same problem with my escort, they have notoriously weak cooling fans that either only partly work or never work at all. I would start there.

SOURCE: Cooling fan wont work

The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.

SOURCE: 1992 corolla radiator fan won't come on

This is the only way to tell if the fan motor is good:
Locate the wiring connector that comes out of the cooling fan. Examine the wires going to the fan motor connector from the engine room harness. Look for the Black with a Red tracer wire going to the fan motor connector FROM the engine harness, before the fan connector. This is the "power in" wire...Remove some of the insulation on the Black/Red tracer wire to expose the copper. Using a suitable length piece of wire, connect one end to the Positive battery post. Being real careful, connect the other end of thie wire to the now exposed copper on the Black/Red trace wire. EXPECT to see a spark. If the fan runs, the fan is good. If the wire starts to smoke, or gets real hot, the fan is locked up, and no good. Please reply if you need further diagnosis info.

SOURCE: 1995 ford escort a/c works great, but car overheats while a/c on

The thing to do is to look in your main fuse box under the hood and check to see if the fuse for that is blown. Another solution is to direct wire the fan from the fan itself to the battery, that will help you to determine if its a relay or if your fan motor has gone bad.If its works when hooked direct you can run a wire to theinside of the car and attch it to a toggle switch.

SOURCE: engine overheating

Try to flush the system And inspect radiator. When moving the engine is also cooled by air. Make sure the water is circulating trough the manifold and the heater core. You can do this by atching a garden hose to each hose one at a time. You may also want to check the waterpump & thernostat..

Overheats when idling. relay was replace and still overheats. fan runs when the a/c is on

When the engine heats up the fan should come on at this time. It is must be the relay or switch. There should be different relays for the AC fav and the cooling fan, even if its the same fan. If you have to you can wire it up directly, so when the ignition is turned on the fan will always run.

Fans do not work, car gets hot and overheats. Checked the fans, the switches, replaced the water temp switch sensor. Still no fan movement.

Make sure the air is bled out of the cooling system,and check the fans to make sure they work,by putting 12 volts to them,check relays also.

You have to check the main relay fan fuse relay and disconnect the fan and try it directly to make sure the fan motor is fine if all this is well into the cavity where the thermostat is a thermal switch that sends it relay the signal to the fan you can disconnect and the fan has to start working if this works the problem is you have the thermal switch. Thanks

My scerity sys went off and I my car over heats I think it needs a new thermastat

maybe your security system monitors engine temp ... it doesnt have to be the thermastat thats bad .. it could be the radiator fan switch or relay bad .. you can tell which by the following.
1. if it overheats only when idling or in heavy traffic but does not overheat while on the road (moving) then your problem is more likely the radiator fan switch, relay or fan motor ..
2. if your car overheats all the time even while driving then it could be the thermostat ..

check belts, coolent level and radiator clogging ..

A/c not working think fan isn't coming on.

Yes with airflow it work (on the interstate) but with no airflow to get rid of the A/C heat causes engine to overheat. Let's look at two possible things...first the A/C condenser fan by the radiator & then the A/C water temp switch.

Check the 30amp CDS FAN fuse (replace if blown) if it is OK then replace the the Fan#3 RELAY (which turns on the A/C condenser fan)...Then if needed replace Fan#2 RELAY (which can also control the A/C fan speed).

The Fan#2 relay can wear out and cause the type of problem your having
