Any thoughts on how to troubleshoot?
If they were installed using a relay kit (which is the correct way) then you should check the fuse. Look near the battery for a small fuse holder, should be easy to spot being its an aftermarket part. See below circled in red.

It could also be a stuck relay that needs to be replaced... start with the fuse and get back to us
