Some 2008-2009 F-Super Duty vehicles with a build date before 11/06/08, and equipped with DATC (Dual Automatic Temperature Control) may exhibit a side-to-side temperature difference greater than 15 degrees Fahrenheit (8.3 degrees Celsius). A temperature difference of less than 15 degrees Fahrenheit (8.3 degrees Celsius) would be considered normal and no repair attempt should be made. Also, it is not necessary to replace the EATC control head or the HVAC. If equipped with manual climate control, vehicles may exhibit periods where the cabin temperature cannot be maintained with the control knob. Some customers may also complain the heat cannot be reduced without rotating the control knob well into the Cool/Blue range. ACTION Follow the Service Procedure steps to correct the condition. SERVICE PROCEDURE Check Actuator Activity: DATC systems may be monitored with the IDS PID ($9910 and $9911 ). Manual A/C systems may be observed through the right side of the instrument panel with the glove compartment door positioned downward. Erratic PID activity or an actuator that appears to be erratically hunting for correct position during the condition should be replaced. Refer to Workshop Manual, Section 412-01, for removal and installation details. The ignition key must be off when replacing the actuator, energizing the actuator before installation on the HVAC case will cause the part to become mis-positioned and correct orientation will be lost. Incorrect actuator operation may result.

2004 – 2006 MAZDA3 DESCRIPTION There have been a variety of electrical problems reported where the root cause may be a poorly secured connector, unsecured wire, or bent terminal or pin to the PJB. Many of these problems have occurred after the PJB was removed and reinstalled, as is done for the HVAC diffuser plate or in-cabin filter installation. Examples of these problems include the following: While performing diagnostics, there is no communication with the PJB Door Ajar Light remains on with all of the doors closed Dome light remains on with doors closed or it is inoperative Fog Lights are inoperative A/C not cooling and compressor is inoperative Power door locks are inoperative Turn signals or hazards are inoperative Brake or ABS light remains on with no system problems found Dimmer switch is inoperative Keyless entry is inoperative (with ignition key reminder NOT on with key removed from the ignition). If a vehicle is presenting electrical problems and during diagnosis there are symptoms present that lead you to suspect a poor connection between a wiring harness connector and the PJB, inspect each harness connector and mating terminal on the PJB to determine if they have a proper connection by performing the inspection procedure below. INSPECTION PROCEDURE 1. Record all DTC(s) if any are present. 2. Record all preset radio stations.NOTE: Perform steps 4 and 5 for each of the connectors to the PJB (J-01 – J-06), one at a time, before moving onto step 6.
