The VCM/PCM very seldom goes bad.

A good repair shop or dealer can run a test with a scanner check on the computer will tell you if most of the stuff is working right in it.
Has the check engine light been on or blinking?

As 16th hippy says we need more info.
Give him some good info.
What is it doing or not doing?
