At first the hight beam indicator came on even though the lights were working at low beam. Then the headlights stopped working completely and the hight beam indicator stayed on, then off later that day. This AM the high beam indicator is on again, but headlights dont work at low beam or high beam? Fuses blown? Relay bad? Wiring problem? Please advise, thanks so much.
Could be problem relays or light switch
SOURCE: I have a 1998 Isuzu Rodeo The head lights won't
The dimmer swich is suspect, Its mixed in with the turn signal switch wiper switch. sometimes it can be found watching the lights to push in and wiggle the turn signal switch if it comes on low at all doing this the switch is bad. It fails alot everyauto parts store should have it and take the covers off the collum to change it don't forget to check the plug that plugs into the switch for burnt connectors or backed out wires. find the wire that comes hot when you put power right on the low beam wire on the headlight ( lows will be on ) there'll be a wrre that came hot that wasn't with every thing hooked up, Unhook jumper and hook right at switch if it works from the switch the switch is bad. Change and ride saftly at nite. Some models have daytime running lights and the fuses for them are in their own fuse panel and have heir own relay this doesn't happen very often.

Always check your fuses and relays just switch your relays out to the other one so that way you know then if that's not it it's usually your ground
