Hi:
Yes it sounds lilke a vacuum leak to me too. Start at the switch (keep in mind the switch could be bad too). Most likely you have a break near where the line goes through the firewall to the engine. Disconnect the supply line from the switch and see if is seems strong.

Let me know what you find.
