no tail lights or tail lights

Hi all, was trying to fix break light on my 97 malibu now I have no head lights, break lights or drive lights. I have checked fuses but I was wondering what else might cause this. Thank you for your replies.

check out the post about no dashboard lights
there is a 15 amp fuse in the fusebox (engine compartment)
but you got to make sure the tail lights will work before changing the fuse
it's all to do with the DRL (daytime running lights ) circuit and ALC ( automatic light control) circuit
there is also a relay for this which can be tested by changing for one of the identical relays side by side in the fusebox itself, like the one for the horn ;)
but nore than likely it's the 15 amp fuse right beside them bud
twas the problem for me and that topic fixed me right up

good luck
