Mini-Drive & Taskem-Tools FAQ

  • Q: Who are these HVAC actuator tools best suited for?

    A: Primarily for Individuals who work in the Automotive HVAC Industry who can use one or both Mini-Drivers, are:

    • Sales Representatives who work in the Automotive HVAC Industry who travel to customers to show them how their blend door motor, temp door actuator, heater blend door actuator, air door actuator or any HVAC doors work.
    • Also, electrical and mechanical engineers that produce and design HVAC Modules for the Automotive Industry and test it using a HVAC actuator palm driver.
    • Lastly, technicians in that same field that perform functional testing of an HVAC Module or dealership technicians as well as the Mini-Drivers are a handy inclusion to your automotive HVAC tools.
  • Q: How do I test a blend door actuator & how does the Mini-Driver make it easier for me?

    HVAC RECIRC Door Testing

    A: In answer to the first part ‘how do I test a blend door actuator’. Well there are many examples on the internet on how to do this, look at this one on YouTube for example However if in that video they were using my Tri-State Driver (Mini-Driver), All they would  have to do is plug directly into the actuator in the car and position the shaft to meet up with the damper door and just drop the actuator onto the screw mounts. They show just moving it once and done, but that's really not true to life. It is a inefficient way to handle the job, and not the safest way to handle a brand new actuator that cost you money.

    Open motor pins are often susceptible to electrostatic discharges or ESD that roll off our fingertips at a whim. The man in the video probably had rubber soled shoes on but wasn't grounded to the bench he was working at, meaning that when he added the 9V battery to the motor pins, the battery will absorb a voltage spike much like a capacitor, but the Tri-State Driver pins can't handle that type of a voltage spike.

    That's just enough over voltage to slam the internal IC and cause future damage issues to pop up later. The one they were showing had a smart driver IC internal to the actuator itself. Tri-State Actuators are special, they need to be handled with care. The proper way to drive one in only to attach the wires the way he did, and then using a switch apply power to the connected pins.

    That video got the job done, but it is always risky to handle electrical devices with general avoidance of caution.

  • Q: How will the Mini-Drivers (HVAC Tools) help me test the following: blend door actuators, door actuator, mode door actuator, HVAC actuator, heater blend door actuator, temp door actuator, air door actuator, AC actuator, actuator motor or recirculation door actuator?

    A: To get a better understanding of how our Mini-Drivers work please visit the Media Page and watch the Demonstration & Feedback Testing Videos.
  • Q: There are 5 ways to drive actuators that can prematurely damage it internally as well as stress a doors drive shaft.

    A: These are the ways generally used by manufacturers of HVAC Modules:

    1. Power supply Directly connect to motor pins.
    2. Direct Battery to motor pins.
    3. Power supply, DPDT Switch & button to motor pins.
    4. Power Supply, Relay and button to motor pins.
    5. Power Supply, Solid State Relay using PLC to control direction.

    This is performed in end of line testers.

  • Q: The best and safest way to drive an HVAC modules actuators and doors is:

    A: 1. Using the vehicles HVAC Control Module - which has a D/A Drive IC to control maximum voltage and current to the actuator. This drive method prevents actuators from receiving excessive stall currents. Control heads are programmed to limit excessive driving time into end stops.

    2. The Mini-Driver from Taskem-Tools Also Mimics the HVAC Module Control head. It has an internal D/A Drive IC which when activated, will internally limit the user from over driving the actuator/door just as the HVAC Control Module would. It’s not our intention to break doors, but to drive them safely so when the module is installed in customer vehicles they aren’t already pre-conditioned to fail.
