I don't know if problems are related? With the turn signals, check for voltage at the turn fuse, when problem is ongoing. I realize intermittent issues are a pain. With GM, Any thing that gets ignition feed, as the turn signal fuse does, I check voltage at the fuse first.
Any applicable trouble codes? Some of the national brand autostores used to check codes for free.
