At night my headlights will run a consecutive twenty or so miles before the switch becomes extremely hot and the lights go out. I have replaced the switch twice and even switched out the wiring harness. When the lights have been on about 5 minutes the relay starts clicking really loud and fast, eventually leading to my lights going out. Relay is also brand new.
Make sure that your ground wires are not rusted off between your radiator support and your fender also the ground strap between your fender and the firewall

I have had the same problem with my 97 S10. I looked at the GM iring diagram and found that the headlight circuit runs directly through the main headlight switch with no fuse or relay at all. The high low beam switch cannot shut the circuit off completely and therefore make the clicking relay sound that is heard. The daytime running light module looks for a headlight on signal and therefore shuts off the running lights. So when the headlights cut on and off the clicking you hear is the day time running light relay, turning them on thinking you are shutting the headlight switch on and off. Inside the headlight switch itself is a thermal metallic circuit protector similar to whats inside a flasher switch. This is the only logical place for the headlight circuit to cut out since it is a directly wired circuit as explained before. Replace your headlight switch for less than 20 bucks from autozone.

saved me the job of answering ,which would have been the same
SOURCE: headlights flicker all the time
Hi, my name is ricky and im 24 yrs old and from Bronx, N.Y . I bought my 03 impala in 04 and i had the same problem in 2007 in which that clicking noise happens. The headlights flicker, and even the gauges inside the car would flicker at times. It has nothing to do with fuses or a relay, please dont spend money on that b.s. like i did..lol I will try my best to explain what i did so that you can save some money and time. READ EVERYTHING AND USE ADVICE AT YOUR OWN RISK.
1st of all - I went to a junk yard/auto salvage yard to find a USED part that i needed. Often there are good parts from cars that have been totalled.
2nd- What i asked for was a Body Control Module. This controls most of the electric issues you are having and costed me about 50 dollars compared to a new one that was over $200 and reached up to $500.
3rd- I went head first under the steering column and found where the BCM was located. Poke around to find it cause it is def. there, hidden well. It doesnt take special skill to remove it or find it.
4th-Replace the BCM, but be advised that after you do this, your car might not crank over.My car did crank over because i installed a automatic starter previously so i could have started it with the remote start.
5th- you MUST take the car to a chevy shop so they can Program your car to the body control module this costed me about $250.
All together this information has to help you in someway.
If you have further questions or would like to make a comment, then e-mail me at " [email protected] "
I hope this helps...im not saying it is a 100 percent guarantee for you, but i had this same problem recently and this was the answer to my problem. By the way, never buy a american car again or a GM product for that matter...Kudos
SOURCE: 2000 Chevy blazer this is the 2nd brand new fuel pump
Spark......EQUIPMENT NEEDED: 1) fuel pressure Gage....Advanced Auto = $45..... 2) needle nose pliers ( fuse pull )..
There is a fuel pressure access valve located on the fuel injector rail. The access port or "shraider" valve has a black or gray screw on cap. Remove the cap and you will see the valve. CAUTION: The fuel rail is under pressure....before installing the pressure gauge, relieve pressure by starting the engine and removing the fuel pump fuse from the under hood fuse box......
Once the engine quits, turn the key to the off position and safely install the pressure gauge. Put a rag around or under the access valve to catch any drizzling fuel. I always prefer to do this when the engine is cool.
Install the pressure gauge, start the engine, check for leaks and read pressure output at idle, record pressure reading.
Also, it should be checked under load but you will need another person to help.
Once you have shut the vehicle off watch the pressure gauge, it should remain steady and not leak down.
Let me know what the readings are.
Regards,

by looking at the manual for my 97 Camaro and if you say that the switch is good then that helps narrow it down a lot, because i found a circuit breaker... not a fuse!...located inside the headlamp switch itself. good luck and let me know if you find it... c.b's. are usually resetable please let me know if you fix it because i have the same car and it might go out on me someday..thanks man! also you can see if your getting voltage on the yellow wire when the switch is in the "head" position..if its not there, then its almost a guaranty that its the c.b.
