Brake light issues

[badclutch2]

Hello new member here. I am working on an 02 Tahoe that came to me with no break lights. Checked every fuse under the hood and behind panel on driver's side of dash, all good. Have power at break light switch, in and out. All tail light bulbs have been replaced or checked, all are good. Distribution block on rear of truck, I can get power when main is unplugged from the block, the light blue wire has 12v but only 0.135 milliamps of current. Which isn't good, lol. My question is do the brake lights run through the turn signal switch or another junction after the brake switch? I've tried Google but I get a different answer every time I check, and I haven't been able to find a body wiring harness diagram. Thanks for any help you can offer.

The brake (not "break") lights do run through the turn signal switch.
