SOURCE: how do i change the heater matrix on a peugeot 405


On paper the procedure for this does indeed involve removing the entire dashboard and it really is a nightmare of a job to do. Having worked on this model before I can however give you this tip.

On the 405 the heater matrix can be disconnected from the engine side as it is connected to the coolant system at the bulkhead. If you then take out the glovebox assembly on the passenger side you will find enough room to work the matrix out towards you.

The only problem is that it is very slightly obstructed by the dash itself when you go to slide it out. If you want to avoid a day and a half of labour all you have to do is take a slight nick - no more than one inch out of the dash which is way down by the passengers feet and really not something you are going to notice a great deal.

The whole heater matrix will then slide out. The matrix can be changed by this method in around an hour. For the sake of an inch of plastic which you are really not going to notice this is the method I would advise.

The alternative is complete removal of the dash assembly for which you will need a service manual and at least a day and a half of your time not to mention the potential problems that occur from removing a dash - upsetting electrics - heater controls etc ........

Hope you find this useful. Please remember to rate my answer. Many Thanks.

SOURCE: Removing_Dash 106

Hello, this is a French Peugeot, you might have to remove the dash. A lot of auto/trucks the heading and air conditioner units are just one component. Remove the hose from the engine fire wall under hood that is if your car engine is located in the front of the car. On the fire wall you'l see some studs sticking out with nuts of them around the internial heading/AC unit. Dis count the hoses (water) I don't now how the air condition line are connected, some are slip joint, some are spring loaded and the use nuts/ferals.

Just take you time and make mental and some diagrams where all these part go.
If you auto is using R12 freon then it will have to be recovered. If it is R134A or 410 just expell it to the atmosphere.
I wish you luck, GB...stewbison

Where is pollen filter on peugeot 607 2005

To replace the cabin filter it is straight forward, open the bonnet, carefully unlatch the plastic cover near the windscreen, with the key in the off position move the windscreen wiper stalk this would cause the wipers to move and park in a vertical position allowing the removal of the plastic cover, Note how it fits under the windscreen, the filter can then be removed and replaced, all in all 10 minutes!

Have a Peugeot 406 1.8 petrol LX on a 52 plate. Smell of coolant in the cab, no visible leak, top radiator hose hot, both hoses to heater matrix hot, bottom radiator hose cold. Air con works fine.

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

@car overheating..loosing coolant but coolant fluid seems to be going into the air cooling system peugeot 607 2.2 hdi 2005, 170bhp auto

There is a leak in the heater core or the hoses to it. The two hoses go into the cabin to the heater and they can get a hole or have bad clamps. The heater core is a small radiator and helps to cool the system.

1998 peugeot306 blocked heater matrix how to unblock

You can take the cold inlet pipe off at the bulkhead and attach a hose pipe to blow it through, make sure the water has somewhere to come out, If this does not work then most likely you will have to replace the matrix.
