The automatic climate control is a sophisticated computer-controlled device. It relies on signals from four sensors.

• The in-vehicle sensor, attached to the A/C control finisher.
• The ambient sensor, attached to the radiator core support.
• The sunload sensor, located on the right defroster grille.
• The intake sensor, located on the cooling unit housing.

This conversion is possible but costly and probably not worth the effort. To judge by past posts on this newsgroup, the automatic climate control is more failure-prone than the manual type and replacement parts are expensive.
