Vehicle overheating, cooling fans appear to be inop. no fuse for fans

Cooling fan relay could be bad . cooling fan fuse - C/FAN 40 amp. under hood fuse box , as are C/FAN lo & C/FAN HI relay's . Video's on youtube on testing relay's an power an control circuit's at the relay base .socket etc... Do you know what a wiring diagram is ? Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year , make , model an engine size. Under system click on engine , then under subsystem click on cooling system . Click the search button then the blue link . Looking at the diagram i see the ECM controls the cooling fans relay's . You mite want to take your vehicle to a qualified repair shop.

A switch is not going to cause engine overheating.
However, a low coolant level, bad thermostat, inoperative cooling fan,or bad head/intake gaskets will.
Do not continue to drive the vehicle with this problem, or you run the risk of ruining the engine and doing expensive damage.

There are lots of things that can cause enginr overheating. It could be anything from cooling system leaks to inoperative engine cooling fans, a clooged radiator, blown cylinder head gaskets, or a defective water pump. The problem needs to be properly diagnosed before anyone can help you with repair instructions.

If the fan not turning on when car engine getting hot,then car will notice overheating.Click this link below for troubleshooting:---http://technoanswers.blogspot.in/2012/02/car-running-hot.html--------To know how engine cooling system works ,click the link below :----Engine cooling components working?

Thanks.

A bad relay will not blow a fuse. The radiator cooling fan must run with the A/C on or the vehicle will overheat and the A/C will perform poorly. First I would check the draw on you cooling fan motor-it may be blowing the fuse, or you have a wire shorted to ground.

? the cooling fan inside the vehicle isnt the same fan that cools the radiator. The AC runs off a compressor pump and the blower motor(fan) distributes it through the vehicle, the blower motor also distributes the heat from the heater core when its set on that. If your motor is overheating and the cooling fan isnt starting the fan itself may be defective or the thermostat that controls it.

The inoperative cooling fan needs to be diagnosed,run the engine until it reaches 229degrees and seeif the fan gets power to turn on if so then replace the fan if not check the wiring and cooling fan relay and repair or replace as needed.

You may have one of several issues. Overheating at a stop indicates an inoperative radiator cooling fan, The no heat issue is more than likely being caused by an air pocket left in the cooling system from the overheating. I would suggst verifyuing the operation of the cooling fans, and then check for any air pockets in the cooling system.

Your tempature sensor was probably the reason why your vehicle overheated but as far as hooking the fan to fuse to the motor isnt a bad thing its the same as installing a after market electric fan it will just keep your engine cooler.

check out with your dealer as you might have a recall to fix this problem.
XT303-S932
X-TYPE
DATE 01/03
MODEL
2002-03 MY
X-TYPE
VIN
C00294-C91719
Overheating - Cooling Fans Inoperative - Replace Module Prior To Retailing - Service Action S932
This Service Action Applies to Vehicles That Have Not Been Retailed
Issue:
The cooling fan module on X-TYPE vehicles may fail under certain circumstances. There are various root causes but the design and quality of the printed circuit board within the cooling fan module are the most significant. The NAND gate used in the circuit is detective causing multiple failure modes, this can result in high engine temperature and overheating due to the cooling fans not operating.
A change has been implemented in production from VIN C91720. On these vehicles a 'Philips' printed circuit board has been used that has a modified voltage spike protection strategy.
Action:
To prevent customers from experiencing this issue, install the latest specification cooling fan module on 2002-03 MY X-TYPE vehicles within the above VIN range that have not been retailed.
PROCEDURE
1. Install new cooling fan module (see Workshop Manual, JTIS CD ROM, section: 303-03, SRO 26.25.38).
Parts Information
Warranty Information:
Warranty claims should be submitted quoting S932 in place of the warranty fault code together with SRO: 26.25.38 and the relevant part number. This will result in a labor time allowance of 0.8 hours to replace the cooling fan module and payment for the part used. Should the vehicle be brought back into the workshop for this action alone to be undertaken, an additional labor time allowance of 0.1 hours can be claimed quoting SRO: 10.10.10 for drive in/drive out.
Warranty claims should be submitted quoting the information found in the table. This will result in payment of the stated time and, where applicable, parts/miscellaneous expense codes.
The options that allow for drive in/drive out may only be claimed when the vehicle has been brought in to the workshop for this action alone to be undertaken.
The SROs and parts items listed above have been included for information only, there will be no requirement to enter the parts or SROs onto the claim.
NOTE: Always perform a DDW claim search first to determine whether this service action has been performed on this vehicle. The warranty selection under the vehicle inquiry will give a listing of all claims against the vehicle. If this service action number appears in the program code field, do not perform this service action.
