I recently purchased. The high beam indicator light always on. The high beam lights were disconnected at lights. Is the daytime sentinel bad? Where is it located?

Welcome to the forums James.
I do not have a wiring diagram for you car, possible one of our members may have it available.
I am not sure how the day time sentinel would effect the high beam light.
I believe the forward pull action of the switch at the turn signal stalk, is responsible for turning on & off the High beam indicator light.
Do the high beam lights click on & stay on and click off ok at the turn signal stock?

update It was the turn signal switch. Which was also high low light switch.
