Check engine light stays on. on 2002 Chrysler Town & Country

Does anyone know how to bleed the vacuum modulator? And where is it on a '02 Chrysler Town and Country. I was told this would reset the check engine light. I have tried just about everything else including replacing the gas cap.

unfortunately, you were told wrong.
Vacuum modulator??
you need a real shop to do a real diag to give you the failure and a bid for repair.
