EGR valve - no vacuum on 1993 Ford Probe

At the smog test, I was told the EGR valve failed the visual because there was no vacuum (all the test #'s were good). I took it to my local small-town mechanic shop and they changed the EGR valve (for $500) and when I went back for the retest, he said he wouldn't charge me for the test because he said it had the same problem - no vacuum to the EGR valve. Now I am out $'s and don't know where to go from here. Help?

May be bad EGR vacuum solenoid or broken vacuum hose?
