Your Fan Control Module or FMC is the long black relay located underneath your coolant bulb, It is mounted onto a bracket on the drivers side shock tower, to test your fans you can take off the temp sensor located on the drivers side tank on your radiator, jump the terminals and the fan should come on in low speed, turn your ignition to the on position and jump them and it should turn onto high speed.
The best solution is to wire the fan to a 12v switched power source on high speed.

SOURCE: engine overheating

CHECK TO SEE IF THE FAN RELAY IS FUNCTIONING BY SWAPPING IT WITH ANOTHER LIKE THE WIPER RELAY IF THEY ARE THE SAME. IF THE WIPERS WORK WITH THE A/C RELAY IN IT'S PLACE, THEN TRY REPLACING THE FAN FUSE. IF NONE OF THESE METHODS MAKE THE FAN TURN ON THEN REPLACE THE COOLANT TEMP SENSOR LOCATED NEAR THE UPPER RADIATOR HOSE INLET TOWARDS THE FRONT OF THE ENGINE. HOPE THIS HELPS YOU FIND THE SOURCE OF THE PROBLEM. LET ME KNOW. GOOD LUCK AND THANKS FOR USING FIX-YA.

SOURCE: 2005 vw jetta radiator cooling fan wont shut off

Check for a switch at lower part of rad. Should see a wire harness & plug on a sensor at bottom of rad. This sensor/switch also operates fan on/off according to coolant temperature. You may need to disconnect battery to get at it safely.

SOURCE: Radiator fan stayed on and drained the battery, why?

I would venture to guess that, based on past experience, that the problem is more likely to be the thermo-switch in the radiator. Find what looks like a large plug in the lower part of the radiator it will have two electrical jacks. If you test this with a meter and there is continuity when cold, there lies the problem. If not then i would suspect a fused relay (pricier to buy). You would find it located just above the fuses... Hope this helps...;-)

SOURCE: need fuse box diagram for a 96' jetta to find out

Then it's not a relay you need to check but the series resistor pack inside blower housing. This controls the speed of the fan.

Radiator fans don`t work on town and country van causing engine to overheat


The radiator fan relay is located behind the grill on the driver's side of the vehicle. There is no relay in the distribution box. There is a 40 amp fusible link, however, in that box.
The relay (behind the grill) works in conjunction with the coolant temperature sensor, the A/C high pressure switch, the transmission temperature sender and the PCM. This relay will run the fans from 30% to 99% of full speed based on the signal coming from the PCM. This is all according to the official Chrysler shop manuals that I have for my 2005 Town and Country van.

It overheats when in traffic ior when it is idling


I have fixed my own 2002 Jeep Cherokee twice for the overheating issue. Overheating can be caused by a number of different problems, but one of the most notorious problems for the Jeep is the 'radiator fan relay switch'. When the temperature thermostat goes over 210, it tells the relay switch to turn on the radiator fan to cool down the engine. If that relay switch isn't working, the fan never turns on and thus your engine overheats. Here's a simple test to check if this is your overheating problem:
1. Start up your Jeep, open the hood, and let it run to the point where the temperature gauge on your dashboard creeps past 210.
2. Once it goes past 210, go over to the engine and see if the radiator fan kicked on. (the radiator fan is right behind the grill, circular with big plastic blades) If yes, then the relay switch is working. If no, then you probably need to replace the relay switch or the radiator fan motor is bad. But more than likely, it's the notorious relay switch.
3. Turn off the Jeep asap to avoid damaging the engine.

You can purchase a 'radiator fan relay switch' from most Jeep dealerships if they have a service dept. It should be around $75.
(I saved over $700 by not taking my Jeep to an auto shop to fix this) To change out the relay switch, you need to take off the passenger side front headlight. There's a black plastic guard behind the headlight and the relay switch is located under/behind that guard. If your Jeep ever experienced this problem before, you may see a cut-out where someone replaced this part before. If there's no cut-out, you can check out this link to see a picture of where to cut.

Once you switch out the part, you should be golden.

I need to locate the bleeder valve for a '96 pontiac sunfire, it appears to have air in the cooling system which is causing it to overheat.


Did you replace the thermostat? If not replace it. Is the cooling fan running? If not check the fuse & thermal relay. If it has a bleeder valve it will be located on the highest part of the cooling system. It may not have one. With the engine cold remove the radiator cap. Make sure the radiator is full. Set the heater control to Hot. Start the engine and watch for escaping air bubbles. Keep the radiator full until you see no more air escaping. If it continues to overheat repeat the process.

Dashboard overheat warning light blinks continuously after 5-mi


It is not the thermostat since it only overheat on stop n go situation. Most likely cause is a bad radiator fan. Turn on the AC and see if both the radiator, and the condenser fan works. They should both be working when the AC is turned on. Lets stick to this for now. Let me know what happened. I don't want to confuse you with too many possiblity.

Nissan Quest 96 Engine running hot


In the fuse/relay box under the hood in front of the battery are 3 fan relays. 1 for low speed, and 2 for high speed. 1 of high speed is back up. check the relays first.

  • Key OFF.
  • Check the 10A RELAYS fuse located in the interior fuse junction panel and the 65A RAD FAN fuse located in the main fuse junction panel. (engine compartment)
