1996 Peugeot 405 1.9TD With Air con problem cooling fans on permanently

1996 Peugeot 405 1.9TD with A/C problem: cooling fans are permanently on when ignition switched on and the temperature gauge is off the scale at the cold end. There are 3 sensors fitted around the fuel filter housing.
1, Brown 2 pin connection I believe is the bitron sensor thermistor measuring 1.78 K ohms across both pins at ambient temp approx 20 deg c
2, Blue 1 pin connection measuring 2.23k ohms between pin connection and earth at approx 20 deg c
3, Green 1 pin connection measuring open circuit to earth.

Checked the Bitron sensor thermistor wiring to Bitron control unit below the nearside headlight wiring checks out ok.

Do you know what the resistance value should be for these sensors and what they are used for?

The Air bag light on the dash board is also on, found the slip ring on the steering column to be faulty , repaired slip ring but the light stays on how is this turned off?

    The 405 cooling fans are controled by Bitron sensor. Haynes manual said so, but it did not show where the bitron sensor is and how it work.
    I wonder what the 3 pins sensor at the coolant is used for.Does it connect to any Temp control unit?

    I have this problem... if I change the fuse (number 2) then the problem goes away until the fuse blows again.I associate the problem with a clicking sound behind the passenger glove box and the red led on the steering wheel flashing on & off, these two things stop when the fuse blows. Is it maybe a dodgy servo mounted behind the glove compartment?

    1996 405 1.9 TDLX Estate with aircon. Problems: Temp gauge not working, radiator cooling fans come on as soon as ignition is turned on, airbag warning light continuously illuminated on dashboard. Haynes manual flits around a bit.

Found a blown 5A fuse in the fusebox under the right side of the steering wheel (near driver-side door). Replaced this, and all symptoms appear to have gone... question is, what caused the fuse to blow in the first place?

    Fuse that had blown was in position marked "2".

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.

We have a 2002 Chevy Malibu.. And the fans want run to keep the motor cool.. When the motor get too hot the car will shut off.. So, what do I do about it??


First check fuses, there are two fans if fitted with air con. The air con. fan only comes on with the air con. The engine radiator cooling fan comes on at operation tem., it is controlled by a censer switch on the radiator .If there is power to the switch and the switch is OK the fan motor is at fault.

Fan will not turn off


which fan? Interior fan, or radiator cooling fan? Is it the radiator cooling fan, or the fan controlled by the air-conditioning?

Run the vehicle, turn on and off the air-conditioning to identify which of the fans in the engine bay is the one triggered by the air-con and which is the primary cooling fan.
If the primary cooling fan is permanently engaged, then first try replacing it's relay as it may have fused closed.

My peugeot 206 temp gage gos into the red and warning light comes on


they either did not put new fans on or they did not connect them correclty its all in the fans the fans cool the water for the engine when it cycles through the engine it cools off there at the radiator and it takes longer to heat up cause allways in any car when you turn on the ac it will turn high or secondary speed on fan so it cools the water even more so check fan if they replaced it motor might be bad or again check connections

Where is the air con relay located - 2000 Peugeot 206 1.6 petrol


if you mean the one thay controls the cooling fan then there is 2 of them located at the front of the car next to the cooling fan. these are probably behind a cover and are green in colour and have 5 pins and the wiring usually corrodes where it goes in to the plugs

if this was any help let me know

Air Con cuts in and out and so does cooling fan


I have a 2008.5 Mazda 3 GS Sport and when you turn the air flow selector to windows or windows/floor, the air condition will turn on automatically. (Can't turn it off.)
