i have a 97 2 door blazer last night i was driving home and the head lights went out on me the driving lights still work fine. i heard a noise around the passenger side dash right before it happened i figured if it was the switch the driving lites wouldnt work and i have no idea what the sound was so please help

 

Have you checked all of your fuses and relays yet? If not, start there.

 

where are the relays located? and how do u check them? fuses look fine

 

There is a fuse panel inside the drivers side door, and also one under the hood which has the relays in it (drivers side...black box). Check all fuses and all relays (not just the ones marked headlights).

 

yup, just switch the relay with another relay of the same type and see if it fixes it, That's the best way to tell if a relay is bad.

 

hey guys i pulled thw switch back and the connector looks a lil burnt it has 11.40 volts to it tho so the relay must be ok so is it the switch it self? the parking lights still work tho, and i found a connector in there that i have no idea what it goes to if yall do it would be nice to know ok guys tell me what yall are thinkin thanks matt
