Hi,

My 89 IROC has been sitting in the garage for about 7 months now, I start it up every once in a while just to keep its juices flowing, but recently I noticed the right high beam light is out when toggled. I tried jiggling the wires/connectors behind with no avail. Before I start tearing into stuff I wanted to see if anyone had any ideas? Low beams, and fog lights work fine both sides.

Thanks in advance!

 

so the left side is working fine? probably just burned out, you can get a test light and check the connector to it to see if it is getting power and if it isn't you'll have to trace it back and see why. Check the grounds also.
