coastline taxis Posted December 11, 2009 Posted December 11, 2009 Ok nice and simple the fuse for the heater fan keeps melting by that i mean the fuse continues to but the plastic that encases it melts any body got any ideas Quote
iannez Posted December 11, 2009 Posted December 11, 2009 sounds like the blower motor is not using up all the power going to it and a few volts are getting past it and going to earth. remove the fuse and wire a bulb across the fuse holder using 2 bits of wire and a couple of male spade connectors. if the bulb lights up you have a fault. do you know how to do a voltage drop test across 2 wires steve. use a multimeter on volts and and stick a probe on a good earth. now put the other probe on the earth wire of the blower motor and turn it on so the fan is running. you will probably get a reading of a few volts and these will be going straight to earth causing the fuse to slowly burn out. the fuse will only blow from a sudden belt of volts. the motor will probably be ok when you first turn it on and gradually start to build up resistance causing the voltage at the fuse to rise slowly and the fuse remain intact but get hot and melting the plastic.

Guest cfryve Posted January 9, 2010 Posted January 9, 2010 Sorry to hear about the lack of grit in South Tyneside coastline we've got plenty over the river. In the sub zero temp last night my heater fan stopped working, bit worrying. It's just the bog standard heater and not climate control and a sharp thump to the side of the dash got it going again. Is the heater fuse in the glove box fuse box so I can check for melt down?, and was it much of a job to change the blower motor assuming mine's on the way out and I can find one in a local scrap yard? Thanks Quote
coastline taxis Posted January 9, 2010 Author Posted January 9, 2010 The one we replaced was on a citroen relay and a dodle to do. Ive never done one on a c5 so youl get better advice of iannez. From what ive seen of them though i would think that the dash would have to come out. if you need a blower theres one on a scrappy weve got Quote
