Technical cooling fans won't start

coolant is fine, lovely and pink and just under max, oil fine, car was fine until the motorway was closed and I hit standing traffic then I got check engine and coolant warning beeps, pulled over immediately and stopped it, give it 5 minutes, started it again, temp was three quarters of the way to red and fan didn't kick in so stopped it before it got hotter
 
anyone had this? tried searching the forum but no joy (on phone at side of motorway!) fuses and relays look fine, but the fan won't kick in and car keeps over heating

I had this issue. Check the sensor placed ON the radiator - it`s located on the right side, at the top, as you look at the engine.
 
I had this issue, took my car in for a cambelt, waterpump etc to be changed and was given the car back. The next day went on a 200 mile round trip and on the way back it overheated. Took it back and i was told it was a radiator relay of some sort, but its location sounds like its in the same place as where daniel said it was. Cost me £37 for a fiat only part plus labour. Hopefully yours doesnt break the bank (y)
 
MES/FES:
Try to command the fan to switch on...
If it doesn't switch on get out a multimeter and unplug the fan and check to see if you get power to it. If you get power to it you still need to do a voltage drop test.

If you do not get power to the fan then check at the relay; You need to figure out if it's a control problem or a power problem; check that you get power to the command side of the relay when you use MES to activate the cooling fan.
Check that you get power to the power side of the relay.

P.S. the cooling fan should have a big fuse .. i think it's a 40A one. This fuse should be before the relay .. so if you are not getting power to the power side of the relay check the fuse.
 
Check the relay fuse ? If that has packed in could be easy fix.
If not try check the senors one being the oxygen sensor it could be damaged, I suggest you dont drive the car anymore since you could cause more damage to the Ecu.

The oxygen sensor(aka lambda probe) has nothing to do with the cooling system.
I do agree that he should not drive the car in this condition, i think the OP realizes that continued use of the vehicle in this situation would lea to severe engine damage.
