1994 Camry that only has 1 headlight working Both high beams work but only 1 low beam I have replaced the light switch and the light dimmer relay and still no luck Is this a ground issue?

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.

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.
Why is one tail light dimmer than others and stops working when headlights are engaged?
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.
Why is one headlight not working on your Nissan 300zx?
Bulb Fuse There may be separate for each side in power dist. box Bad ground
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.
Where is the fuse for the headlights on a 1991 Corsica?
Check repair book but my 89 has circuit breaker in headlight switch. There is ground wire on body in front of battery. Bad ground will cause breaker to activate so unbolt ground and clean connection. Could have bad dimmer switch which is on column under dash and may be hard to remove without lowering column. I unplugged old switch, plugged in new dimmer switch, set it to dim, and wired new switch to column so now only have dim lights as old switch is connected to activator rod which goes to turn signal/dimmer handle.
Why won't heam beam headlights on 1974 vw beetle work when low beams do?
If low beam works but high beam doesn't then: It is unlikely that both headlights burnt out the high beam filaments at the same time. I'd check each headlight beam with another headlight beam you know is working on both high and low beam filaments. If this works the higb beam, then the beams are no good. Another check, to make sure that both filaments in each headlight are working, is done by connecting 12 volts of power across the three terminals at back of the beam (negative to ground terminal and positive to first the lowbeam terminal and then the highbeam terminal). If both filaments light, headlight beam(s) are good. Brightest light is highbeam. If in doubt as to which terminal is which, look at the connector, the white wire is Highbeam, the yellow wire is lowbeam, the third wire is ground. So, now you know the headlight beam are good, but if problem is still not fixed, check the fuse for high beam. See your owners manual for location, or just check all the fuses. If the high beam fuse is OK, check the dimmer switch. If looking at the dimmer switch, the middle wire (56 termainal) is white with black stripes, this is the power in to the dimmer switch from the headlight switch (dash). The left wire (56b terminal) is yellow and it is the low beam power from dimmer switch to fusebox, the right wire (56a terminal) is white and it is the High beam power to fusebox. If the low beam works as you say, a quck check of the system and the dimmer switch, is to exchange the yellow (low beam) wire and the white wire (high beam). If the high beam nowworks but the low beam doesn't, and the fuses are all good, then the dimmer switch is faulty. If the fuses are not OK, check all the wiring first. Check to make sure all the wires are connected from headlight switch to dimmer switch to fusebox to each headlight. Look for shorts (burnt wires) in the curcuits, since if the fuse(s) burnt out, it did so for a reason. Repair first any burnt wires. Replace the fuse with the same sized fuse. This should fix your problem.
99 Chevy s10 one headlight is much brighter than the other headlight to TS swapped headlights still the same problem im i missing a ground connection on the bad headlight?
Sounds correct-- clean all connections and perhaps run a ground wire from headlight body directly to ground for test
Why is your drivers side head lamp burning dimmer that the passenger side?
you have a bad ground
