Better to ask on a Peugeot forum as you say if it is a similar common fault to the Renault you might get a faster answer?

 

Yes OK, may do that or ask a local Peugeot / Citroen specialist. If anyone else on here knows about Peugeots even though this is a Renault forum what the fault may be please let me know.

If the rheostat goes then the fan won't work at all so if the fuses are OK and the motor tests Ok the rheostat is the prime suspect.The rheostat is in the outside air trunking going down to the motor,to access it open the bonnet,take the plastic scuttle panel trims away (you may need to remove the wiper arms,I haven't changed one in a very long time so you'll have to forgive the holes in my memory) and on the nearside there is an air intake,remove that and you should be able to look down into the fan and see the rheostat.You twist it through 90 degrees and it should come out,you will see an obvious problem with the wires in the unit usually,they tend to blow apart.:d

If you fit a new rheostat,make sure you have the ignition off as the fan will start instantly even if the control is set to off,it will only work at a low speed but will still make a nice job of taking the skin off your fingers!.

With aircon,I hope it's not a leaking pipe running down the side/back of the engine,they are a complete #### to fit......if your Aunt ever says to you that she wants the aircon to work and you have it regassed and either the high or low pressure pipes leak run away and hide.:rofl:

Hope that helps.

EDIT.Actually,thinking about we broke a 306 at work not so long ago and we have the complete dash out of it so if I remember I'll take some photos to show you where everything is and I'll also check the rheostat in it and see if it any good.If I don't get back to you before the weekend give me a shout.....

 

certainly on my old 106 there were a set of resistors on the heating nob control, and one failed and i went from 4 speeds to 3, replacing the resistor fixed it.
