My heater blower on my 86 Defender 90 packed in the other day but pinpointing where the fault lies has so far eluded me. The story so far is as follows ;
Checked fuse but OK
Checked fuse holder but no power showing ( with switch and ignition on )
Checked both sets of wires going into blower and one showed 0 volts and the other showed 0.01 volt ( switch and ignition on )
Checked switch in on position for restance but OK
Put a test wires to heater blower direct from battery and hey presto blower now working.
So I'm now thinking it's a wiring fault but someone mentioned it could be a problem with the relay for the blower motor ( which would kind of would explain the strange reading of 0.01 volts showing on one set of wires ) the Haynes book makes no metion of a specific relay for the motor blower so now I'm a bit perplexed. Does my model use a relay for the blower motor and if so where could I find it?
Cheers.
