have just put my kenwood cd head unit in the willy and now my heater fan doesnt work???? it works every now and then??? i know the wires behind the head unit are quiet tight and compact behind the head unit, but it seems as tho i have a loose connection within the fan???? what normally happens the fan will come on if i leave it on and then when i switch the engine out it wont come on again??? anyone else had similar probs?????
