SOURCE: volvo v70 air con fault

This is probably a clutch problem on the compressor, either buy a new clutch or get a second hand compressor and swap the clutch over.

SOURCE: cooling fan not working

The fans only run when the engine reaches approxminatly 235 degrees F. on the guage that is near the end of scale just before guage show "HOT" I don't think you have a problem, allot of folks out there don't know about this.

SOURCE: OVER HEATING

In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan.  Swap the relay with another relay, replace the fuze.  The other fan should come on when the a/c is turned on.  If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET.  ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM?  DO YOU SMELL EXHAUST IN THE COOLANT?

I have a 1999 cadillac deville. My cooling fan is not turning on. My car is over heating. Is there a connection?


There is nothing really in the water-related part of the system that has anything to do with the fan. The hoses, thermostat, heater core, etc. are simply a conduit to move the water through the engine to provide cooling. The fan is the crucial element to avoiding overheating. While the car is in motion, air flows through the radiator, cooling the coolant down and removing the excess heat. Once you stop, however, or get in a stop-and-go environment, there is limited airflow through the radiator to provide this heat reduction. That is where the fan comes into play. What makes the fan work depends upon what you are asking the vehicle to do. Testing the fan circuitry is rather simple if you understand a few things. The fan only needs to run to cool the engine if the engine coolant gets above a certain temperature (usually about 220F). The fan will be ordered on and run until the coolant drops to about 180-190 (thermostat temp). The confusion is that the thermostat has something to do with turning the fan on. The thermostat only controls the flow of water through the system. It stays closed until the water temp reaches it setpoint (usually 180-190F), then open to allow water to flow through the engine. There is a coolant temperature sensor, usually installed near the point where the thermostat is, and it sends coolant temperature information to the ECM. The ECM uses this information to control fuel-air mixture and to control the cooling fan to operate when needed. The fan and the fan relay can be tested very easily by simply turning on the car's A/C. Even if your A/C unit isn't working, simply putting the dash controls to an A/C position, will automatically power up the cooling fans, since the A/C requires CONSTANT airflow thru the font of the engine to maintain cooling. If the fans don't work in the A/C position, then the problem is not likely to be the coolant temperature sensor. It is more likely to be a fan relay or the fan itself.

Cooling fan relay location for a 1992 corvet


the air con fan comes on with the air con switch. the engine cooling fan comes on when the engine temp. censer reaches operation temp. most times the air through the radiator when driving is enough to keep the censer cool and the fan not working if you stop at lights for any length of time it will come on.

89 cadillac eldorado, engine cooling fan and interior heater fans intermittently do not turn on when they should, they will reach 107Celius over heat light does not come on and coolant is circulating as it...


hi,
some vehicles have a synchronised twin electric fan system that operates only when the AC is turned on, can you manually turn off the AC and see if that changes what you have just described.
If not then the climate air ( AC ) sensor may be faulty.

1989 ford f 150 i been driving and the engine stop fuel have don't start


could be fuel pump,check for fuel see if fuel pump supplying fuel and you are getting spark.make sure ignition timing is correct and the idle speed setting correct check the under hood emissions information label.also check engine make sure engine not over heating check cooling fan clutch see if cooling fan clutch is okay by turning it by hand if engine is hot cooling fan should have resistance if engine is hot, if cooling fan feel loose no resistance the fan clutch is bad.

usually when the fan stays on is for a certain amount of time to allow cooling off the engine but if it goes on and not going off there has to be some kind of a short or another wire allowing that to happen without shutting off
