Volvo fan continues to run after not being able to start car

SOURCE: I have a volvo 940

Sounds as if you have set the immobiliser, does your car have the volvo guard alarm system fitted, (is the red light on the window frame?) I found that when reconnecting the battery if you just tap the connector on the terminal 4-5 times before connecting it it would reset the immobiliser and the car will start

This sounds like a gearbox issue. Take it to a garage with diagnostic equipment and get the fault codes read.

SOURCE: FAn keeps running when car

There will be a sensor switch that switches the fan on and off, either on the radiator or close by maybe on the thermostat housing. you should find it by following the wires from the fan. Disconnecting the plug will stop the fan running, but your engine will get hot so watch your temp (you could connect a switch between the two connections on the disconnected plug as a temporary measure but replacing the switch should sort it out. If by chance the fan keeps running when the wire is disconnected from the switch its a short in the wiring. Oh, the fan will run on for a while after the engine is switched off but it should stop after about minute (once it has cooled it down) Check coolant level.

This is normal. The fan will run even after the car is shut off until the engine gets below operating temperature. Most vehicles will do the same thing. Although I think thirty minutes is an excessive amount of time. Most could run up to fifteen to twenty minutes. If the car is retaining heat somehow this would cause it to run longer. Happy motoring!!!

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.
