System Diagnosis - Air Delivery & Temperature Controls

^ Diagnosis for the Temperature Control portion of this system is based on malfunction codes stored in the Electronic A/C Control head. When a code has been set, the F° (or C°) indicator will flash. Refer then to HEATING AND AIR CONDITIONING (SEC 1C1) for code diagnosis.

^ If the air delivery appears incorrect, refer to "System Check" and perform the Vacuum Diagnosis.

^ If the temperature coming from the air ducts does not change when adjusting the temperature control button from 60°F to 90°F or from 90°F to 60°F, perform Chart #2. Chart 2 Air Flow Temperature Does Not Change
