you're right SYDDONNA if it's there it might as well work. I said that about my A/C all last summer but I suffered anyway because I couldn't afford the Robert Dinero to get it fixed. I do as much as I can myself, and someday I'll get around to the tach, maybe when I'm ready to part with the car. Best Wishes,
