This is probably not a ground issue because if the ground were open then neither high or low beam would work on that particular light and if it were shorted then you would blow the fuse when you attempted to use the high beam.
OK, first off for the obvious, have you tried replacing the light bulb?
If replacing the light bulb doesn't fix it then chances are this is an open circuit in the + side to the high beam that doesn't work. You will need to use a voltage meter or testing light and find the location where the open is in the wire and repair it. These usually occur at connectors or splices but not always.
What else can I help you with?
Why is my new passenger-side halogen headlight dimmer then my new driver's-side halogen headlight even after I switched to check it is always the passenger's side that is significantly dimmer?
Dim lights are almost always a bad ground connection on the dim light, just loosen and retighten the ground wire to restore the connection.
How do you fix headlights that dimmer than they should be?
Usually the ground wire that comes out of the headlight that is fastened to the car body is the culprit. You will usually find the wire terminal from the headlight plug attaching to the car body or chassis ground not too far from the headlight. Fairly common problem.

sounds like a poor ground.
1989 Chevrolet silveradothe parking lights and dash lights went outbut the head lights still workthe fuses are goodcould this be the dimmer light switch?
It is probably either the switch or a bad ground somewhere. Try the switch first. On my truck the switch itself is going bad. most of the time if you just keep turning the switch on and off then it will come on. If not you'll have to replace the switch. Logic tells us that IF the headlights [high and low beams] are WORKING, then the dedicated HEADLIGHT dimmer switch is OK, as the headlights are the only thing that dimmer switch controls. The HEADLIGHT dimmer switch is ONLY in the headlight circuit, not the other related circuits such as instrument panel and parking lights. On the other hand, there is a SEPERATE DIMMER switch, usually in the MAIN light switch, for controling the brightness of the instrument panel lights, and as answers 1 and 2 suggest, the problem is more likely in the main switch which controls the instrument and parking light circuits, but again, not in the switch dedicated to controlling high and low beam headlights.j3h.

Turn the power back on and test the dimmer switch to ensure it is working properly.
What could cause a headlight to be too dim?
Run a ground wire to that headlight. If it gets brighter, there is a problem with the ground in the wiring harness.
Why is one headlight on my 1983 Toyota pickup suddenly much dimmer than the other?
Ground circuit. 25 Year old ground is telling you that it is getting corroded. Clean the male on the light and the female on the connecter. If no change, work backwards in the circuit, cleaning all grounds, until brightness is restored
93 Chevy Corsica headlights wont come on?
Be sure headlight switch is ok. On my 89 there is ground wire on body in front of battery and dirty connection will activate circuit breaker in headlight switch. Could be dimmer switch on column under dash which may be hard to remove without lowering column. I unplugged old dimmer switch, plugged in new switch, set it to dim, and wired it to column so now only have dim lights( but can drive at night) as old switch still connected to activator rod which goes up to turn signal/dimmer handle.
