The fan stopped working abruptly and the next morning when we went to start te care the battery had gone dead due to what seems to be a fan that was stating on after the ignitionwas turned off. Please advise on this .. -
Answer 1
Possibly a faulty relay.Stuck-on killing the battery then failed because it over-heated the contacts 'til the battery went dead.Check for power at the blower motor and work backwards .OR consult a manual and work forward. -
