Motor only runs on low speed, even if voltage is applied to the high speed terminal. I diconnected all wires from motro terminal block. I measured resistance between high and low speed terminals. No resistance, just pre continuity.

The resistance would be low, or almost zero even if it were working right. Check wiring very closely at the terminal block inside the motor for anything touching. The only other explanation is that the high and low wires have shorted inside at the windings and only the low is making a circuit. It is possible to tap the 'end bell' off the motor and possibly find the shorted wire. Be sure to scribe the end bell and the case with a mark so you get the two lined back up going back together.
I really think it might be fight at the terminal block, look very close for the two wires making contact there.

Replacing a heaters blower motor

The indoor blower motor is powered by 115 volts or 230 volts, either way it wires the same.
Every motor be it a single speed or multiple speed will get the 2 legs or power,
Line 1 and Line 2 or L1 and L2 to make it easy.
Common always gets a leg all to itself, you cannot run both legs of power to the speeds as the speeds are on the Run winding, that is a direct short, and you cant run a leg to Start or it will turn backwards! This is how we unlock compressor's that get stuck!
1 leg or power ALWAYS goes to Common.
The remaining leg of power, say it is L2, it goes to the speed desired or if a single speed motor, it can go to the terminal on the Run capacitor that is wired to the Run winding, A Run capacitors terminals are Run and Start.
Note the capacitors leads coming from the motor are both brown, 1 has a white stripe
the capacitors leads are obvious in that respect as well as being the only 2 leads that have female type ends that are for sliding over the run capacitors terminals, it does not matter which lead goes to what terminal as long as both get their own.
The remaining leg of power we are calling L2 will be going to the speeds desired,
Cool uses High while Heat uses Low speed, High speed is controlled by a fan relay or fan board on the high speed terminal or cool.
While the low speed is controlled via temperature delay, time delay or a fan board on the low speed terminal or heat.
There is no need to get an exact replacement motor, as long as the shaft diameter, frame size, rotation, voltage & HP rating equal or better,
(you can go bigger HP, never smaller) you will be ok.
Some universal or trip saver motors have bushings for various shaft sizes, and an ability to reverse rotation by inverting a plugged set of leads. Belly bands are used for most applications so even if your OEM motor has built in motor mounts there is a belly band that can be used to replace that motor perhaps cheaper if not faster, some OEM motors can be days away from being available

The heater fan in my 2001 cavalier is blowingat really low speeds. Still different ans speeds at each setting but maybe onl at 10% of what they should be. Any ideaof the cause?

Even in high speed it's not what it should be? I would measure the voltage at the motor wire itself while going through all the settings. I would also check the voltage coming into the resistor block.

Fuse number for winderwiper

Hi Maddie, I'm glad to help! Below, I have posted a diagnostic procedure to see why the wipers are not working on your Dakota. Hope this helps and have an awesome day Maddie!


The following are wiper motor system problems,
tests to be performed to locate the faulty part, and
the proper action to be taken. If the malfunction involves
only the delay mode, switch, or wiring, see the
diagnosis for Intermittent Wipe Module and Wiper/
Washer Switch.
Motor will not run in any wiper/washer
switch position.

(1) Check fuse 10 in the fuseblock module. If OK,
go to step 3. If not OK, replace fuse and go to next
(2) Check motor operation in all wiper/washer
switch positions. If not OK and fuse blows, go to step
5. If not OK and fuse is OK, go to next step.
(3) Place wiper/washer switch in LOW position and
listen to motor. If you cannot hear it running, go to
next step. If motor is running, check motor output
shaft. If output shaft is not turning, replace motor
assembly. If it is turning, drive link to output shaft
or linkage is not properly connected. Replace worn
parts and/or properly connect drive link to the motor
output shaft.
(4) Connect a voltmeter between motor terminal L
and ground strap (Fig. 1). If there is little or no voltage
(less than 1 volt), move negative test lead from
the ground strap to battery negative terminal. If an
increase in voltage is noticed, the problem is a bad
ground circuit. Make sure the motor mounting is free
of paint and that mounting fasteners are tight. If
there is still no indication of voltage, the problem is
an open in wiring or faulty wiper/washer switch. If a
small increase (greater than 3 volts) in voltage is observed,
the problem is a faulty motor assembly.
(5) Disconnect motor wiring connector and replace
fuse. If fuse does not blow, motor is defective. If fuse
blows, wiper/washer switch or wiring is at fault.
Motor runs slowly at all speeds.

(1) Disconnect wiring harness connector at motor.
Remove wiper arms and blades. Connect an ammeter
between battery and terminal L on motor (Fig. 2). If
motor runs and average ammeter reading is more
than 6 amps, continue to next step. If motor runs
and average ammeter reading is less than 6 amps, go
to step 3.
(2) Check wiper linkage or pivots for binding or obstruction.
Disconnect drive link from motor. If motor
now runs and draws less than 3 amps, repair linkage
system. If motor continues to draw more than 3
amps, replace motor assembly.
(3) Check motor wiring harness for short between
high and low speed circuits. Connect a voltmeter or
test lamp to motor ground strap. Set wiper/washer
switch to LOW position. Connect other lead of voltmeter
(test lamp) to terminal H of the wiring harness.
If voltage is present, there is a short in the
wiring or wiper/washer switch. If no voltage is
present, go to next step.
(4) Set wiper/washer switch to HIGH position.
Move voltmeter (test lamp) lead from terminal H to
terminal L of the wiring harness. If voltage is
present, there is a short in the wiring or wiper/
washer switch.
Motor will run at high speed, but not at low

Motor will run at low speed, but not at high speed.

Yes, it will handle the voltage...

It is odd indeed as a normal AOSmith two-speed motor will have quick-connect AND screw posts for line connection terminals. If you are certain there are only two screws yet the motor is a two-speed then the answer to the first question is yes; you'll need a female quick-connect terminal for your second line connection to the A terminal.

Replaced Single Speed Pool Pump Motor with 2-Speed Motor

You will need a two speed time clock to really take advantage of real energy efficiency savings. Intermatic makes one that fits in place of the original t104 time clock. You will need to run an additional wire to the pump as well. You will have the ground. Then one common wire that is always hot whether or not you are on high speed or low speed. You could make this a white wire. Then a black wire for your high speed that is energized in high speed and a red wire for the low speed. It is important that the high and low speeds not be energized at the same time, otherwise you will hear a very unpleasant sound coming from the motor, and failure and shortened life of the motor will be realized.

You are correct. Appaently you have a short in the winding connection and that is not a do-it-yourslef type of repair. Unfortunately, the cost to fix something like that is high since it is labor intensive and you may want to look into a new motor since the chances of additional or near future failures is likely. If you would like a quote on a new motor, contact us thru and be sure to include the voltage you are connecting to as a 1.5 HP is available in both 115 and 230VAC.

Driving and speedolight

The driving light and all the 'dashboard' lights are supposed to be ON when the key is turned to RUN--even if engine is not running. (blame federal regulators for this dumb idea. Driving light should be wired to come on when engine is running--a simple wiring connection change.)

the comment 'and light increases in strength' is a key clue. It describes low battery voltage. Either the battery is not properly charged, or it is faulty. First try 'jumping' the cycle with a good car battery. If the started works--proves the problem is low battery voltage.

The alternator is working--but is the voltage regulator controlling the voltage? Try measuring the battery voltage (not driving) but in neutral at various increasing engine speeds. The voltage across the battery terminals, everything off, should measure about 13.2 volts. With engine running, it should quickly rise to 13.5 V at or just above idle, and not rise much/any more as engine speed increases. If it keeps rising to above 14 V , the voltage regulator is not working and will quickly overcharge and destroy your new battery.

3 speed switch wiring schmatic

On a 3 speed switch you usually have 4 terminals, and they are marked L1, 1, 2 and 3.
L1 which is line voltage from the electrical cord or wall plug, #1 low speed usually a red wire from motor, #2 medium speed usually a blue wire from the motor and #3 high speed usually a black wire from the motor. That is if the fan is low,medium and high, if it says high, medium and low then reverse #1, #2 and #3
