2000 TOYOTA CAMRY Blower motor control

101 BODY ELECTRICALÐAIR CONDITIONING
AIR CONDITIONING
 DESCRIPTION
1. General
The air conditioning system in the new Camry has the following features:
The rotary switch and lever type heater control panel is used.
As in the previous model, an air conditioning unit that incorporates a blower, heater and cooler unit, has been
adopted.
The duct size of the blower unit has been enlarged.
An aluminum heater core has been adopted on all models.
The defroster nozzle inner wall is modified into a radial configuration for smoother air flow.
A defroster±linked air conditioning start up control, which automatically engages the air conditioning when the
defroster mode has been selected, is provided.
The air conditioning amplifier which is integrated with the ECM has been adopted on the 5S±FE engine model.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.
