my mum has a 1998 1.4 306 with air con and all the toys.she rang me to pick her up because smoke was pouring out from under the dash on the passanger side.i have had a good look and it had blowed 5 fuse's.i have also checked the wire's and there are two plugs by the heater motor,one is white one is grey.i have found that the grey wire that goes into the white connecter has all melted,does any body no what this wire is for because the manuel does not say thanks
