Where is the turn signal relay for a 2000 Chevy Tahoe located?

The turn signal relay location on a 2000 Chevy Tahoe isn't a single, easily accessible location like a fuse box. It's integrated into other modules, most likely the Body Control Module (BCM). Therefore, there's no standalone relay you can easily replace.

If your turn signals aren't working, the problem is much more likely to be a faulty BCM, a wiring issue, a bad switch, or even a burned-out bulb. You should take your Tahoe to a qualified mechanic or dealership for diagnosis and repair. Trying to find and replace a non-existent standalone relay will be fruitless and potentially damaging.
