Electrical problems>>>Where do I start?

[jawsmon]

I have a problem with pass side front turn signal, drivers side head light and both front fog lights not working. I have checked all the fuses and didn't find the problem. The relays seemed a bit warm. 

I started up the truck before checking the fuses with a probe style test light. Several fuses didn't have power on either side. I thought this was a little strange since every GM vehicle I've ever owned has had power at every fuse once the engine was started. I don't think this is part of the problem with the lights, just strange to me.

I will be checking the ground strap next.

 

What are your thoughts on this problem?

 

2020 GMC Sierra 1500 Denali with 23K. It's lived in the NW all it's life. We hardly ever salt the roads.

Warranty?

It's still under warranty. Got an appt. for next week. Just curious if others have had a similar problem with the lights.

I will check the condition of the ground strap between the block and the firewall that's located below the battery today. I have heard of others having several problems that were resolved by replacing a corroded ground strap.
