One of the most popular advancements in automotive technology over the last 1years is the introduction of automotive air conditioning systems, both heating and cooling. Automotive engineers use blower motors to force heated or cooled air through the interior of the vehicle to adjust interior temperatures. I go over checking for voltage, how to check the capacitor, how to check each of the electrical windings individually with resistance, and checking for electrical shorts.
Keeping motors clean is an important step. The heater blower motor is located behind the glove compartment of your vehicle .
Disconnect the negative and positive power supply.
The black wire is usually the negative.
To check the purple wire for current, use your . How To Check And Replace fan motor and resistor. Note: the start winding is labeled incorrectly in the video. See comments below for more detail.
In this video we go over testing blower motor resistors found in Ford vehicles with manual climate control.
This video will explain you testing of Split Air conditioner blower motor in simple Hindi. An expert can measure current draw . Otherwise, normal old-age issues, such as bearing failure, cause seizing, which leads to massive electrical failure. A less common cause is insufficient voltage to the blower.
The first step in diagnosing blower motor failure is to check to see if there is demand for the blower. If there is, and the blower is not . I only works on high speed when the blower resistor circuit is bad. Blower motor resistor symptoms.
Air Conditioner doesnt blow any air - how to fix AC blower - HVAC control board replacement - Duration: 11:34. I cover Genteq ECM Fan Motors 2. You need to make sure that you are correct in your Troubleshooting because these are not generic motors. Each motor is programmed by the HVAC Equipment Manufacturer . The pressure switch measures the vacuum created by the blower and verifies the blower is operating at speed.
The control attempts to close the switch by.
If you have trouble with your HVAC blower motor , this tech article will show you how to test it. See just how to figure out if the resistor or the blower motor is at fault.
