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?
have the same problem?
