Quite suddenly one day at the lake my 2000 F150 4x4 Lariat Supercab seems to have the abs pump still running after turning the key off. I'm thinking maybe the module or the relay. Can anyone tell me exactly where the relay would be located? And how do I single that particular relay out. Are they known for going out? For the mean time I've unplugged the abs. Any other suggestions or ideas would be appreciated
