turn signal flasher

where is turn signal flasher and emergency flasher module 2003 chvy express ? trying to trbl shoot , I have no turn sigs or emerg flshers .

I found my turn signal relay under the dash, right of steering wheel, left of radio. It is clipped to the underside of the dash. I had to get on my back and reach up to pull it out. Part is about 2" sq. x 1" wide. My left turn signal isn't working. Tried to clean the contacts in the relay but still no luck. I will need to replace the module but havn't found a supplier on line yet. Still looking.
Part #25746427 TURN/HZD/BRL/DRL

Good luck.

**update**

"Turns" out all I needed to replace is a burned out bulb. The relay module flashes rapidly to alert you of the condition. Yeah!
