About ready to use the sledge... Just got (2 weeks ago) a 2000 Blazer 4dr 4x4 for the wife. Everything seemed fine until she noticed a problem with the headlights... So here is what it does... The DRL turns on all 4 lights (hi and low). When you turn on the headlight switch, all 4 come on (with no highbeam indicator on inside.) When the lights are off and you flash the lights (with the multifunction switch) you get all 4 (and the highbeam indicator inside works.) Using the multifunction switch does nothing except when the lights are off. The Automatic lights turn on all 4. I noticed that a ground was replaced/installed on the pass. side connected to the lowbeam blue wire. (disconnecting this new gnd wire = no headlights at all) I thought maybe someone had installed some sort of Quad mod but I don't see any diodes b/t low & highbeams (found that info on one of the forums.) I've replaced: headlight relay DRL relay headlight switch multifunction (turn signal) switch I have another headlight harness (incase I missed something in the headlight wiring) coming from s10Warehouse. I kinda remember seeing somewhere, someone said that it might be a problem in the BCM. Does anyone buy that? Anyone have any ideas (besides taking it to the dealer.) Thanks AJ
