HEATING SYSTEM TROUBLESHOOTING MANUAL

Model All Mazda Models
Category U
Bulletin No. 93-04
Date September, 1993

DESCRIPTION

This Service Bulletin contains a new Heating System Troubleshooting
Manual that was developed by the Mazda Canada Quality Assurance
Section. The diagnostic procedures were developed and tested in
Canada during a Cold Weather Test that took place in February 1993.
The diagnostic procedures were tested on vehicles in which customers
had complained about a lack of heat for several winters. The
effectiveness of these procedures was confirmed.

SPECIAL NOTE

This same manual will also be used as a hand out for all forth coming
Training Courses on Climate Control Systems.

HEATER AND DEFROSTER TROUBLESHOOTING MANUAL

INTRODUCTION

An investigation was conducted using customer vehicles at dealer-ships
across North America over a two year period. The investigation was
conducted to determine if there were any concerns that were difficult
to repair using existing Mazda repair manuals.
The following list represents items most commonly left unrepaired or
undiagnosed by the dealer.

1. Air leakage between the blower unit and the cooler unit.

2. Missing or mis-installed sealing grommets in the firewall.

3. Incorrect operation of the thermostat.

4. Improper usage of the recirculation and fresh air mode of the
ventilation system.

In order to assist in the correct diagnosis and repair of Heating
System concerns the following troubleshooting manual was developed.
See Fig. 1. for a visual description of the Climate Control System.
