On mine, it's the fourth relay from the inside out. In case they are in a different order, it should be the relay with two large wires and two small wires coming into it. One of the large wires is power and the other goes to the fan. One of the big wires should be purple with a black stripe. Spray WD-40 into the socket before plugging back in. This has been a BIG problem spot for GM. The wiring, not the relay, is what causes the problem. the contacts get hot and lose contact, then get hotter and quit working completely. I your connector looks burned, it may still work if you use the WD-40. The relay may still be good, too. This cost GM a lot of head gasket repairs due to stupid engineering and overheating. Typical GM.
Low coolant? Bad thermostat? Heater core air bound, restricted, or plugged? Water pump not circulating coolant? Temperature control switch not working?
No/low coolant, bad thermostat, dirty/plugged radiator (inside and/or outside of it), air pocket in coolant, electric fan relay, temp switch for fans, bad fans.
There is a sensor that is in the overflow bottle that may be bad causing the "low coolant light" to illuminate. The coolant level switch is located on the bottom side of the coolant tank. The switch contains a reed switch and a magnetic float. When the coolant level is normal, the float rests away from the reed switch, causing the switch to be open. When the coolant level decreases in the coolant recovery tank below a specified level, the float rests on the reed switch and the switch closes, illuminating the LOW COOLANT light. The coolant level switch is a part of the coolant tank. If the switch needs to be replaced, the coolant tank must be replaced.
It is located on the left side of the engine between the 6th and 8th cylinder on the block.
It is on the driver side head, back by the last spark plug #5 cylinder.
The switch is just across from the battery located in the rad reservor, to remove it and clean the sensor probe, you have to remove the battery.
Not plugged in.
No, if nothing is plugged in pulling current then you are using no electricity by leaving the switch in the on position.
Low coolant? Thermostat not closing allowing engine temperature to rise? Plugged heater core? Air bound heater core? Water pump not circulating coolant? Heater control cable not adjusted properly? Bad selector switch?
Check coolant level Test and/or replace thermostat Make sure heater core is not plugged restricted, or air bound Make sure coolant is being circulated by water pump Check heater control switch and /or cable
brake switch out of adjustment, master cylinder comp port plugged, rear brake hose collaspsed or ebrake cables seized
The computer uses the coolant temperature sensor to decide when to run the fans. It is below the radiator cap on the cylinder head.
Remove the retaining ring at the top of your 1991 Acura Legend ignition switch. The ignition switch cylinder will slide out. Remove the wiring harness from the end of the ignition cylinder. Reverse the process to install your new ignition switch cylinder.
There is no such thing as a: temperature switch, on your Ford focus, the coolant temperature sensor is located on the front of the engine.
radiator coolant switch, pcm coolant switch, relay , pcm , related circuitry or fuse.
its called your heater core No it is called your heater control valve
Could be,low on coolant, add coolant and look for leak, plugged up rear heater core, try flushing heater cores, stuck open thermostat, replace stat,

where is the location of the fuel selector switch on a 2110 4 cylinder ford escape? or fuel selector switch circuit.
Called an Engine Coolant Temperature Sensor, Located on drivers side of engine under the EGR with a 2-wire connector. 13mm deep dish socket is needed for removal
Replace ignition switch for 1993 buick century?
Where is the backup light switch on a 2002 buick century?
A unidirectional current controller device is a type of electrical on/off switch. In order for an item to work that is plugged into a particular outlet, the switch must be in the on position. It is like having lamps plugged into outlets that are controlled by only one switch.
switch itself or key cylinder?
