Hi Grant ...... I've swapped the complete loom and fuse block from a 1 / 78 car ( ex Jarred Viper Green ) and by looking at the fuse block it had the problem in that car so I've just tranfered the problem from one car to another. I've changed the fuse block for one with the same B desingation and I still have the problem.
Think I'll have to do some serious circut tracing. It's in the Autocross car we're putting together so for now I've just disconnect the heated rear window so it's not drawing lots of amps through that circut. Send me a PM about the electric window stuff. No need for photos. Cheers ..... Geoff
