How to Locate and Check Blower Control Switches, Heater Relay, and Blower Resistor on a Toyota MR2?

The heater blower switch is situated behind the left end of the heater control panel on the dashboard. To access it, the instrument cluster finish center panel must be removed, followed by the four mounting screws of the heater/air conditioner control panel. Once the panel is pulled out enough to disconnect the electrical connector from the back of the heater blower switch, the large locknut can be removed after taking off the knob, allowing for the removal of the switch itself. Continuity of the heater blower switch should be checked, and if it does not meet specifications, the switch needs to be replaced, with installation following the reverse order of removal. The heater relay is found under the right part of the dashboard, requiring the removal of the instrument panel under cover and the right kick panel to access it. Continuity between terminals 1 and 3 and between terminals 2 and 5 should be verified, while there should be no continuity between terminals 4 and 5; if these conditions are not met, the relay must be replaced. To test the relay operation, battery voltage should be applied across terminals 1 and 3, and continuity should be checked between terminals 4 and 5, ensuring no continuity between terminals 2 and 4; if the relay fails to operate as specified, it should be replaced. The heater blower resistor is located next to the heater relay, and continuity should be verified between terminals 1 and 2 and between terminals 1 and 3, with no continuity between terminals 1 and 4; if these conditions are not met, the heater blower resistor must be replaced.

Toyota MR2 Blower Control Switches

The Toyota MR2 Blower Control Switches help in adjusting the rate of the HVAC fan so that the occupants can control the airflow and temperature of the cabin. Found within the heating and air conditioning circuit, these Blower Control Switches turn a driver or passenger demand into a spinning blower motor at the desired speed and volume of air through the vents. Each of the Blower Control Switches works with relays and sensors that send temperature and humidity readings to the system, which directs warm or cool air as requested. When the switch is operational, it allows the fan speed to change and thus provides comfort to the driver or passenger. It also prevents a dash error code from showing up if the airflow is restricted. A malfunction in any one of the Blower Control Switches causes the fan to stop, run at the wrong speed, or turn on heating when cooling is selected or vice versa, affecting cabin effectiveness inside the Toyota MR2. Essentially, regular attention should be paid to Blower Control Switches to protect HVAC components that are present in every Toyota MR2. Furthermore, this will protect the Toyota driver's MR2 during varied weather.
