I have got a peugeot 406 1.9 gldt on an n plate

The front and rear license plate mounting brackets work nicely for strapping on a small child...but seriously refer to the instructional video in the link to mount a child safety seat in a car with or without LATCH points. The Peugeot 406 was required to have LATCH mounting connectors effective in 1999 in the US and Canada. The location of the mounting connectors should be detailed in your owners manual.

You have one or more defective glow plugs.

try changing the switch or check wiring behind it go for cheapest elimination option first.

have heating in my peugeot 406 hdi when car is ticking over but when i drive for few mins the heater goes cold

it could be a slight leak from the heater matrix (check for damp in the passanger foot well) its self or the thermostat may be sticking this may cause the bottom hose to stay cold. you could try removing the thermostat and running it without it and then putting a rad weld in the coolant system to seal the matrix.


let me know if this helps


cheers big mike

near the bottom of the page click link "Peugeot Owners / Peugeot fuses"
next screen click on the model, (406)
then look for your VIN or DAM number

406 is prone to damaged internal contacts in the ignition key barrel, one of the cables there supplies power to the heater blowers. What happens is there is a large supporting clip that takes the weight of the bundle of cables from the ignition barrel, this becomes loose or fails and allows the weight of the bundle to hang on the back of the barrel, the end result is loss of supply to various systems as well as damage to the key barrel itself. Drop the under steering kick pannel and try a wiggle of the bundle while you have everything switched on and the engine running, if you get intermittant blowers running you have found the fault!

switch has broke inside itself

This seems very very common... I managed to frig one recently by joining two wires at the switch end together.. Without looking I can't tell you which, but it was simple logic to work it out.. Desparation made me try, but it took 10 mins. From (my sometimes lame) memory I think one of the grounds was missing, one of the pins will have no voltage on it relative to either ground or 12v, it'll be that one!
The car was wrote off about two weeks later, poor pug..

u changed the bulbs? blower, when not working try and tap it, i think it will work as i think your car is high milleage and brushes are worn in the blower, it is under glove box.
