New information: In my previous request for help I said that my headlights are working; however, the passenger's side high beam is not working. When I start up the car the DRL light and headlight (on the dashboard) click and then flash. The headlight light then goes out but the DRL flashes on the dashboard while I am driving. The dimmers work fine.No daytime running lights and only one high beam, head light HELP???
Check your DRL relay that is located in the fuse box. Also check the connector under the battery box for corrosion. (Not a smart place to put a connector) GM really messed up with the wiring on the 98-00 cavaliers headlights.

On my 2007 Honda CR-V The DRL code appeared on the dash board. Additionally I had only one high beam (on the passenger side); both low beams were fine, but I did not have a Daytime Running Light on the drivers side. The DRL code was really misleading because the real problem was that the high beam element in the headlight bulb was burned out. Note that the daytime running light is not a seperate bulb -- it is the high beam element which is powered at a low voltage. Once I replaced the head light bulb everything worked fine and the DRL code on the dash board was gone. So if the DRL message appears what you really need to do is replace the headlight bulb (there are YouTube videos which show how to do this - but search for headlight replacement, not for DRL fix). Be careful not to touch the new bulb with you hands since premature burnout can occur from the grease off your skin. I got my bulb from Wal-Mart for $8.88 (it's a 9003/HB2 for the 2007 CR-V) -- that's a pretty cheap fix.
I’m inclined to believe you have a headlight switch problem and here’s why. There are 2 fuses one for each of the headlights on the vehicle. For the daytime running lights (DRL) to operate the fuse and wiring to the right head light has to be good, because it supplies the power for both headlights in the DRL mode. The fuse and wiring for the left headlight has to be good because the DRL relay needs power from that fuse to operate. The DRL relay in turn provides a path through the left headlight and wiring to ground. When you pull back on the dimmer switch, you are activating the flash to pass circuit of the headlight switch assembly. Because the flash to pass mode works you then know that the high beam wiring and headlight bulbs are in good condition. This also tells you that the ground circuit for the headlight switch is good. In many newer vehicles, the headlight switch doesn't provide power to the lights. The headlight switch has now become the path to ground to complete the circuit. The headlight switch and the high/low beam dimmer control are one assembly so when you replace one you get the other free. Such a deal! My coffee bet is on the headlight switch assembly.
First identify if your day running lights (DRL) are working. The DRL
and high beams will work on the same relay. If your DRL are working, but not your high beams, you may need to
replace your high beam relay which is found in the fuse panel under the
hood of the engine at the right back corner; near the firewall, and
passenger tire strut mount. If there is also a problem with your DRL
with the high beams, its likely the DRL relay which can be found tucked
under the dash.
There's usually a cover that says "relays", "fuses", etc. Lift the cover and look underneath, it should label the relays. If not, consult a manual or repair book. Try swapping similar relays from know working accessories if you don't have a new one handy.
Most DRL's are controlled by a relay. The relay malfunctions after a while. Need to go to the dealer and purchase a DRL relay. Once you see what it looks like open hood and match it to the bad one, then replace. If you can not locate it the library has mechanical books for you make and model to look up location of the drl relay.
I had the same problem with my daughters 1998 Cavalier and found that the salt used on the Michigan roads and corroded through a wire.The when the light are used for driving lights they are hooked up in series on the 12v line and the wire between the lights had corroded.It has been a while and don’t remember exactly the point where I found the problem but it was by the driver side head light.
Some time back I found some data on a similar website suggesting that the Day Light Running circuit board, just under the steering column, developed cracks in some of the soldered joints. Your high beams should also be affected with loss of day light running lights. Resoldering repaired the continuity of the circuits. Ours is now working quite reliably. Some of the defective areas developed slight brownish discoloration, that's how I was told to recognise the areas to be resoldered. Hope this will help you solve your problem.
