Is the TNS relay in the fuse box under the hood a 'turn signal relay' and if so could that be the reason the turn signals and emergency flashers will not work on a 1999 Mazda 626?

The TNS relay in my '99 626 is blown, causing the dash lights, front & back parking lights, and taillights to not work. Turn signals and hazard lights still work. Quick test: The A/C relay is exactly the same part. You can swap relays to check the TNS relay. Be warned that swapping relays can result in more damage if a short caused the first one to blow. Doc
