C240 not starting

There is no malfunction message. When I put the key in, and turn it, the radiator fan turns on high speed, but the car doesn't start. I don't hear the starter clicking or anything.

SOURCE: MY WILL NOT START THE CAR C240 MERCEDES BATTERY IS NOT DEAD

I am assuming that the engine won't even turn over. could be lots of different things. The simplist is to make sure the car in in PARK , won't start if not. Other things could be , Security imobilizer if you have one. Does your key have a electronic chip in it ? Try your other set of keys if you have one. Check if battery connections are clean and tight.

SOURCE: '02 C240 alarm

If you have noticed any strange electrical problems beside the alarm. Test a theory for me
before you start the car use the key in the drivers door lock lock then unlock the door hold the key in the unlock position till your cars window and sunroof open. Next Start the car close windows and roof turn on your AC high beam headlights fo lamps radio and wipers if your car runs little rough replace the battery and have the alternator tested. The alarm system is the clue happens when the alternator and or battery are not working properly PLEASE LET ME KNOW ON THIS

05 rendezvous, where is the fan sending unit located


Are you talking about the radiator cooling fans ? If so there is no fan sending unit as you call it ! The fans are controlled by the BCM/PCM !
The engine cooling fan system is controlled by the body control module (BCM) and the powertrain control module (PCM) or engine control module (ECM). The BCM performs the calculations as to how long, when and what speed the cooling fans should turn on. The BCM then sends a class 2 message to the PCM/ECM to engage the cooling fan relays. If there is a malfunction with the BCM, the PCM/ECM will control the engine cooling fans independently. The engine cooling system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the PCM/ECM to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood accessory wiring junction block. The ground path is provided at G100.
The BCM and PCM/ECM command Low Speed Fans on under the following conditions:
?€¢
Engine coolant temperature exceeds approximately 106?°C (223?°F).


?€¢
A/C refrigerant pressure exceeds 1 310 kPa (190 psi).


?€¢
After the vehicle is shut off if the engine coolant temperature at key-off is greater than 140?°C (284?°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes.

The BCM and PCM/ECM command High Speed Fans on under the following conditions:
?€¢
Engine coolant temperature reaches 110?°C (230?°F).


?€¢
A/C refrigerant pressure exceeds 1 655 kPa (240 psi).


?€¢
When certain DTCs set.

Where can I find the mercedes C240 radiator fan terminal


The fastest way to check a radiator fan is to turn on the a\c while idling , this should automatically turn on both fans at once, if they don't come on first check the fuses then the fan relay. If the motors are working when the a/c is on then your thermoswitch has gone bad (its located somewhere on the radiator, look for two wires coming out of it)

2002 isuzu rodeo 4 cyl twin electric radiator fans when cold turn igniton on fans run on high speed , it has a brand new battery and the alternater is checked ok it will not run hot and after it runs


Assuming the check engine light is not on, I would want to know what the engine temp sensor is doing.
A scanner would tell you what the temp sensor is showing - if it is unplugged or there is a problem with the wiring the fans will run as a default to prevent the engine from overheating. It could be a fan relay but I doubt it. A relay usually works or not.

Why does my 1997 mecedes benz e420 run hot when I turn on the air conditioner


Couple of reasons. You may need to have the Radiator backflushed to remove sediment. You also have an Electric cooling fan which may be malfunctioning. They (fans) often have more than 1 speed and high speed may be broken so it can not keep up with extreme heat.

Some fans use more than 1 relay to switch the fans and the second stage relay may be bad.

Overall, the A/C coil is placed in front of the Radiator and depends on airflow to function. This makes the air available to the Radiator much hotter so the Radiator is having a hard time cooling the engine. The Electric radiator fans kick up the airflow to help both systems out.

A dirty radiator, old antifreeze, etc. can affect performance.

I hope my solution is helpful. Radiator shops can service most Brands.

My 2005 chevy impala 3.8l is overheating. had a new thermostat put on it. noticed that only thedriver side fan come on could that be the problem


if you turn on the ac the other fan should come on, However I don't believe that will cure the problem your having since having the ac fan and the ac turned on pretty much cancel each other out, Putting a new thermostat on Just allows the thermostat to open and close at the set temp that's on the thermostat , Not really fixing the problem, ( unless the thermostat is stuck in the closed position would replacement of it help ) what I would suggest is to completely flush your cooling system, and add new antifreeze, antifreeze like oil breaks down, other heating problems can be caused from the car not tuned properly, check the timing , and components associated with the car running properly, ( plugs, rotor and cap, spark plug wires, )

Sould the second radiator fan along with the first?


I would presume you are meaning an electric fan that has two fans together. Both fans dont always run at the same time. One is a high speed fan and the other a low speed fan together in the same shroud. Engine temp determines if and when they turn on. *****CAUTION!!!!! Fans can turn on any time the key is in the on position even if the engine isnt running. Do not put your finger in the fan or handle them unless the Neg (-) battery terminal is disconnected.*****

I have never seen the radiator fan working for


Well the first thing I can tell you is that the radiator fan should kick on as soon as you turn on the a/c. That's because of the extra strain it puts on the engine. So, if you don't see or hear the fan go on with the a/c, it's probably dead. You could also unplug the fan and run a jumper wire off of the battery to see if it goes on.

Car is overheating even with new thermostat


these cars have relays for the fans, replace relays and the fuses. if still dnt work, replace the temperature sensor. make sure u check the wiring, it may just b a loose wire.
