96 GRAND MARQUE CLICKING NOISE IN DASH BOARD

1996 Mercury Marquis

I have a 1996 Mercury Grand Marque LS, w/ auto climate controle. When I change the temperature there used to be a loud clicking sound from inside the dash board. Now it always blowes hot air no matter what the temperature is set to, even with the A/C on. Could this be the controle unit, or is there a faulty vacuum valvle?

It's the srvo that attaches to the blend door, either the door or servo needs attention.
