My indicators have stopped working also the heater

The motor has a diode pack of resistors built into it so either this is defective or the brushes in the motor are sticking ,the motor is under the passenger side dash on models with AC ,pull the cover down and with the engine running and the blower turned on thump it with your fist ,it often works .

Tired serpentine belt thrown. replace belt. The reason that the heater has stopped is the ECU has realised that there is no charge so shut down heavy load(s). Before replacing, do check that water pump and alternator turn freely along with the jockey wheels.

Have you checked the fuse first.

The fuse must be in the main fuse box. The position of the fuses is normally marked on the inside of the fuse box cover and also in the owner's handbook. If you don't come right with these, work your way through the fuses looking for a blown one. To ease your search the fan fuse it should be around 25 to 30 amps.

The blower is not in the engine bay proper. It is below the air inlet grille under the windscreen, Access may be through the heater/ventilator unit in front of the console.

thier is a resister situated on a card that plugs into the heater / blower assembly under the dash board these are prone to burning out, at best replace the card but beware the connecting plug sometimes burns out then you have to replace the wiring loom

hope this helps

check the earths on hte chassis behind the headlights

There is a 4" long Green ceramic resistor by the blower motor, prone to fail, I think Valeo does them on the aftermarket.

hi, had same problem twice with my 98 expert , first time it was heater control board(the slider sends a varying voltage thru the thin green wire at the motor plug, to a semi conductor encased in an ally heatsink when checking motor operation check thick red wire for 12v, and thin green for 1.5-4.5v, depnding on slider movement, and thick green for earth conn) , second fault was overheated conns both at motor conn and at relay(mine was bright green cased one behind glovebox), Terry

when checking fuses pull one and check the wire lead or flat metal lead going from side to side of the fuse if you dont see a burn or dark spot its ok replace it and continue this until you have found the bad ones of check your bulbs sometime a bad bulb will not let the others work properly.If these do not work chect your signal switch also known as a multifunction switch.I would not attempt to chang the blower if its not a fuse because they can be hazerdly.

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.

its all in one unit with the fan and its about 250€
