2003 Ford Taurus air condition switching to defrost at high rpm; speedometer, tachmeter, odometer quit.

Hi Bret, Most modern vehicles have an engine main relay. The relay in question turns off all auxiliary circuits for the starting operation, (when you turn the key to the start position) which consumes more power than any other operation. I would suspect a problem with the wiring to that relay. A loose or bad connection at the base or to the base. The relay in question will usually be a five pin normally open normally closed relay. It should be identified by the directory printed onto the plastic cover of the relay / fuse cover. Also check the secondary connections to the battery. Regards John
