Flickering Headlights

Started with only high beams now lows are doing it also after an hour or so. With light switch on lights flicker on and off and you can here the relay in the glove box click with the flickering. I replaced relay which did not fix problem. If I pull the left relay out while this is happening it stops and lights remain on.

Which of those three relays do what and what else might be the trouble here? Thanks for any help.

It might not be the relay. I just recently had a similar problem. Your headlight switch (where you turn them on) is short circuiting causing the switch to heat up and then turn off and on. It is an easy replacement. Even for a novice it takes about 10 minutes. You can find a replacement at Autozone for about $13.00. If that does not work (which I highly doubt) you might want to check your relays
