Hi all, Was donated a LHD )we are in France) Peugeot 806 which we love but the heater/blower/aircon or something is constantly squeaking. If you push the switch right over to full blast it sometimes eases off, but it's gradually getting worse. Can't work out exactly where the noises are coming from with the bonnet open so how do we access it all from inside please? So hoping a squirt of WD 40 will fix it, or are we likely to need a whole new unit? (We are on a very tight budget) Thanks.
