FLASHING SERVICE 4WD LIGHT

hi there!the 4wd for my 2000 blazer works perfectly.but sometimes, the service 4wd and all the 4 4wdlights on thedash flashes for a second or so.sometimes once a day,sometimes5-10 times!I have looked under the car and have seen oil dripping from the gearbox,well not dripping but the end of the gearbox was wet and dirty!and two days ago I was looking around the engine and found that one of the houses was off from the solenoid valve I have put the house back on.but the lights still flashing maybe not that often as withuot the huose.thanks for your opinions!!!

RE: FLASHING SERVICE 4WD LIGHT

it will flash to let you know to change your gear oil, or when it's getting low.
