Is there a relay for the High beam indicator in dashboard 1990 Dodge van?

It's highly unlikely a 1990 Dodge van uses a relay specifically for the high beam indicator light on the dashboard. The indicator light is typically a very low-current circuit directly controlled by a switch in the headlight switch assembly. The high-beam indicator light is illuminated when the high-beam circuit is activated, directly from the switch itself, not through a separate relay. The relay is used for the *high beam headlights* themselves (because of the high current draw), not the small indicator bulb.

If your high beam indicator light isn't working, the problem is far more likely to be:

* A blown bulb: The simplest and most common cause.

* A faulty headlight switch: The switch itself might be malfunctioning.

* Wiring issue: A break or short in the wiring between the headlight switch and the indicator lamp.

* A bad ground: A poor ground connection can prevent the light from illuminating.

Before assuming a relay is the culprit, check the bulb and wiring first. A wiring diagram specific to your van's year and model would be helpful in troubleshooting. You can often find these online through sites specializing in automotive repair information.
