97 blazer flickering headlights

[darrell a johnson]

When I drive at night, after about 15 mins my headlights flicker from low to high like I'm flashing my brights. I also here a clicking in the glove box. I think I found relays. Could this be the problem? HELP! ( the fuses are o.k.)

Could be a bad headlamp switch (has a circuit breaker built in).

Is it difficult to replace the head lamp switch?. I've already replaced relays in glove box and problem still exists. Thanks for your reply.
