It sound as though your fan temperature switch might be faulty making the computer thing the engine it hot even though it is not. This is where I would start, it might not end up being the problem, but it is not and expensive part to replace and it is fairly easy to change.

SOURCE: key stuck in ignition

Hi I am vortash I had this once and it was the same vehicle I cut a thin piece of plastic from an old credit card just slightly thinner than the key and applied some superglue to it onl a very tiny amount in the middle of the plastic I applied it with a pin so not to put too much on .. I then eased it into the keyhole next to the key waited 5 minutes for the glue to dry and managed to gently pull it out but if you dont fancy that idea I have also seen it done by drilling a vey small hole in the top of the broken Key with a Dremel and a fine drill bit and a small allen key with loctite on it pushed and tapped into the hole .. that worked also .. hope this helps Regards Vortash

SOURCE: when I turn off my ignition, my heater fan will keep running

I just started experiencing the same problem. Yes, typically after rainy days, I can never get the interior lights to go out after the ignition key has been removed. The car acts as if there is a door open. Now, my latest problem is with the heater fan. Of course, putting the control in the "off" position will turn it off but you can turn it on and off with no ignition key installed. I'm also having problems with my heater core too so it's been a pain in the but!!

I believe this problem has also caused my battery to die which is why I'm on this site in the first place!! I can't get into the car with the keys and the dead battery won't allow me to unlock the car!! When it rains it pours!!!

2005 Volvo S40 with key stuck in ignition. It turns off but key doesn't come, out of the steering wheel. Please advise needed, if lock change is required estimated cost of part and labour please.


Some ignition system locks will not release the key unless you push in towards the column while turning further off. It is a safety device to stop in advertent removal of the key while moving. Try that first.

Why does my fan keep running in my 2003 Volvo S 60 after the car is off?


It can be faulty fan relay.The relay is not turning the system off.Or its wire short issue.Even with ignition off ,the fan relay is getting power so its not letting the fan to turn off.Bypass the fan control relay and see if still the fan works with ignition off or not.

Radiator fan keeps running after engine is off


I think it is supposed to run for a while even after you leave the car. These keeps cooling the engine so it doesn't overheat as the engine sits still.

Volvo Radiator, Thermostat and Sensors Your cooling system's temperature controls include all coolant temperature sensors, Volvo thermostat, Volvo radiator or expansion tank cap, cooling fan(s) and fan clutch (if equipped). These cooling system parts function primarily independent of the engine but control the engine either through cooling or by sending control signals to your Volvo's electronic systems.
The Volvo thermostat is a spring-loaded valve that opens and closes based on the temperature of the coolant flowing through it. A high temperature reading followed by a drop to normal temperature (or a continuously low temperature) is a common first sign of a sticking Volvo thermostat. However, many other conditions may cause these symptoms, so you need to know how to eliminate each possibility.
The Volvo radiator or expansion tank cap is also a spring-loaded valve reacting to system pressure. It serves to maintain proper system coolant level at predetermined pressures. It must always be replaced with an exact replacement cap with the same pressure setting. Never use other caps except for short-term emergencies!
A belt-driven fan blade for pulling air through the Volvo radiator is usually on the Volvo water pump pulley and should have a fan clutch to control it. The fan clutch allows the fan to turn with the belt at low engine speed and "free-wheel" at higher speeds. A bad fan clutch either doesn't allow the fan to spin at low speed (overheating in traffic) or doesn't allow it to free-wheel at high speed (potential overheating on highway or reduced gas mileage).
An electric fan can be either by itself (usually front-wheel drive) or auxiliary (used with a mechanical fan). Both types are controlled via a temperature sensor - in the Volvo radiator or upper Volvo radiator hose or on the Volvo thermostat or Volvo water pump housing. This sensor is usually an on/off type switch with a fixed temperature setting. (Some vehicles may have 2-3 settings for multi-speed fans.) This sensor is commonly called an "auxilliary fan switch".
Other common temperature sensors are: 1) gauge sender (variable output); 2) warning light sender (on/off type); 3) lambda and/or fuel injection sensor(s) (variable to control fuel injection settings); 4) thermo-time switch (cold start valve control). Your Volvo may have other sensors as well.
Temperature control is critical to both performance and emission control. Unfortunately, this system is the most difficult to troubleshoot without proper equipment and diagrams. It's even more difficult with computers that adjust timing, idle speed, vacuum and fuel delivery automatically to make up for potentially faulty temperature sensor signals.
Maintenance of your cooling system sensors is virtually impossible since there's nothing really to "maintain". Keeping them clean both internally (coolant replacement) and externally (engine cleaning) is the best way to ensure trouble-free driving. Checking and replacing all parts at the factory-recommended time or mileage limits helps as well

I have ust serviced my 2001 volvo s40 and now the


did the sevice light come on before you serviced it? when you "serviced" it I assume you changed the oil and now need the service light reset.
I bought the 1998 S70. it got time to change the oil. Being how I am I changed the oil myself. I had to call dealership about resetting the service light.
they said $29.96.
I said 29.95?!!! how much if YOU would have changed my oil and reset the light?
they said $29.95.
so I learned you need to access the OBDII to reset the light.after service. hope this helps.
