HI, related to my fan heater problem. The relay in the bonnet fuse box (K7) appears to have it's coil supplied by the EDC (Electronic Diesel Control Unit) its a blue 12V relay and works fine in the main beam socket.
However, when measuring the volts applied to the coil connections witht he ignition on I get 12V on one and about 5.5V on the other.
I would like to find the EDC to see if it is putting out 5.5v or whetehr me wiring fault on my fan blower is related to a bigger damaged loom issue, ie. -ve is picking up from another 12v powered circuit through damaged insulation....
First call is to find the EDC. Mines a 2.5TD.
Any help much appreciated. I'm bl**dy freexing...
Ta. JBW.
