A single click usually means a bad starter (unless the engine is stuck and can't turn over.) Rapid clicking almost a buzz would indicate dead or discharged battery or poor electrical connection from battery to starter.
To be a little more sure, use a voltmeter to measure voltage while trying to crank. Below 9.5V indicates not enough electrical power available - battery issue. Higher voltage then 10.6V indicates plenty of juice, but the starter isn't working.
The blower motor resister for an Acura Legend drops the voltage to the blower motor. This is what allows the motor to run slower for the medium and low settings.
I used Valvoline VV155 MaxLife SAE 5w30 Motor Oil in my 1990 acura legend
To replace the starter in a 1989 Acura Legend you must first disconnect the negative cable on the battery. Disconnect the starter motor making sure you label each of the wires as they are removed. Remove the bolts which hold the starter to the engine and slide out the starter. Position the new starter to the engine. Torque the mounting bolts using 32 pounds of foot pressure per bolt. Connect the wires to the starter using the labels as a guide. Reconnect the battery cable and check the starter operation.
The manufacturer of the 1989 Acura Legend recommends 10W-30 motor oil. A heavier motor oil can be used in extreme climates.
The clicking noise you can hear is the starter solenoid clicking into place. If the starter motor does not turn the engine immediately, it is probably the best place to look. it sounds like the starter motor is faulty.
it's the blower motor
Yes , it is an interference engine
i had a 1990 acura legend my blower motor was located under the passenger side dash board
either clean and tighten cable connections or get battery tested. if not the battery, it is the solenoid or the starter If it is clicking and not starting at first, but starts after a few tries, its your starter taking a dump. Replace it.
Possibly the Blower Motor has stopped working. This was the case in my 1994 Acura Legend. I just replaced it, and now the heat works great again!
that test indicates that you need to replace the starter motor.if no clicking in this test , you would replace solenoid first. but clicking indicates solenoid works,so replace starter motor
dead battery bad starter solenoid bad starter loose or corroded battery or starter cables
