98 Discovery I Headlight Issues
I have a 98 Discovery I with 190k miles on her and yesterday I started her up to drive home from work and the headlights would not come on high or low beam. I changed my bulbs about 6 months ago but unplugged them and sure enough they are not getting any power. Checked the under hood 30a fuse and it is good. Removed the switch and tested it and it is good. Running lights and tail lights still work so that is strange. Checked my grounds and they are good. Under dash fuse box has 4 fuses for the headlights and they are all good and get power when they should depending on if the highs or lows are on. In short the fuse box is getting power from the headlight switch BUT the power is not making it to the headlights. I searched RAVE over and over again and I do not see a relay or anything after the fuse box. I even went as far as to trace the headlight wires all the way from the headlights to the firewall and found no issues. Not sure if this has anything to do with it but a few days before I accidently left my headlights on and drained my battery and had to jump it. Headlights still worked then. Everything electrical on it still works other than the headlights. Could it be my fuse box? Is there a relay I am overlooking? I know it has several relays hidden under the dash but RAVE shows that I do not have a headlight relay. So confused and lost as what could be the problem. HELP

check the fuse for power in the engine compartment MF4 fuse 30 amp if it is good and have power verified by a meter continue by turning on the headlights then check the fuses f11 and f10 both are 10 amp fuses located in under dash these are the high beam you should have power when the high beam is selected and low beam fuses f4 and f5 are also 10 amp fuses they should have power when low beam is selected if no power is verified on either 4 fuses during it selected beam replace the headlight switch or it can also be the connector at the switch pin 2 for high beam or pin 5 for low beam. If power is verified at the 4 fuses when beam is selected then check connector C204 behind fuse box under dash fascia.

30A fuse in the under hood fuse box is good. The four fuses in the interior fuse box are good. With low beams on power is to the two low beam fuses. With the high beams on there is power to the high beam fuses. Dash lights come on. Tail light and side markers come on. High beam indicator on the cluster does not come on. No voltage at the headlight bulbs. I ripped my fuse box out and found the connector for the headlights to the fuse box has corrosion. Cleaned the connector and it is good but it didn't help. I got a steal on a brand new fuse box and that should be at my house tomorrow. I hope that is the issue because I don't see anything between the fuse box and the head light connectors. At the plugs and at the fuse box I find no shorts to ground.
