turn signal relay

I have a 2002 Chevy Trailblazer. The other day I lost my turn signal lights and my hazard lights. The head lights, brakes all work fine. I checked the mini-fuses in the control box under the hood and under the rear seat and they all look good. None burnt out.

I suspect that it is a relay that has gone? Do you agree?

If so... where is this relay? In the manual none of the micro or solid relays says "Turn signal relay" Is there another word for it or is this located somewhere else?

Thanks.

There is a turn signal/hazard flasher module located behind the lower left side of the dash.

Here is a guide to help you test the wiring

The entire wiring diagram for the exterior lights is attached below. It shows the wire colors on the connector for the module, this will help you locate it
