James Blackburn-Lynch: My 2001 SL2 blower motor works on low speed (1) and high speed (4) but not
on 2 or 3. I checked the resistor slot as you said in the video and found
12 volts there no matter what setting. I kinda thought the voltage would
change as it went through different resistance circuits. If the resistor
pack is fine, why are 2 and 3 not working? Weirdly, sometimes when the
blower motor is going at speed 1 (which it does as I move it from 1 to 2
and 2 to 3), sometimes it jumps to 4. Any further advice?
John Strauss: you are measuring Voltage not Current. Current is measured by putting your
multi meter on Amps not DC and connecting the meter in series within the
circuit you are measuring, which in car circuits is close to impossible.
just a friendly correction. not trying to be a jerk.
justmepat Jachimiec: HELP HELP NEED VIDEO REPAIR AC HEATER BLOWER SWITCH, I have told my
mechanic the blower control lever for low is now on high. I no longer have
different control levels. Can I buy the whole bottom AC heater control,
help where can I buy a new one. I live west suburbs Chicago, or maybe I
should go junk yard
maxie0789: When I test the voltage on the switch it jumps up to 18+. What could that
douglas tucker: great video ... had my dash all torn apart to replace resistor .. took my
trusty ole simpson 260 V.O.M. out to double check ... found bad wire @ the
motor plug in ... looks like the plug might have been HOT as it is slightly
melted & disfigured. Found the same wire harness @ junkyard for $2.00 and
spliced it in about 4" back from old plug .. works like a charm ... Plenty
of A/C & heat NOW !! Thanks !
Rob Brown: Hey Rich, when you are checking the ground of the blower motor electrical
connection, what ground in the cabin area are you touching the black
multimeter wire to?
MrScotty46: my blower switch works 'sometimes'
maxie0789: Hey. I'm getting a high voltage when I test the switch power. What could
Ray Keefer: My 97 sl1 saturn the blower works but not on high, what could it be.
labattsipa: heres a question. my blower is very weak at the third setting,,all the
others are normal. resistor has been changed. whats next?
Joseph Knight: I'm trying to fix the blower on a 01 Saturn SL1. The blower works when
hooked up to a 12v source. I have good ground and voltage at the blower
connector, but only when there is no load. As soon as I plug the blower in
or add test light I get no voltage at the purple wire. Any ideas? I tried
swapping the relay with the fuel pump relay with no success. When metering
the relay socket, I have good ground and voltage on all three bottom pins
(when the blower switch is on).
James Laskowski: Hammer tap restarted blower motor on 2000 xlt ford ranger
Altobellodobermans: My meter has two settings on my meter which are DCV and DCA which one do I
use? Also on the ground wire test I have nothing coming up on meter. So
does that mean it is my blower motor thats toast?
Michael Tesfaye: Can this same concept be used to diagnose other makes/models, or is it
specific to the Saturn S-series?
Tom Bender: Good job; right Around The Bases... (baseball )...
b: the resistor goes on the blower motor causing it to blow slowly and thats
the first thing that goes on toyota tacomas at least mine did and replacing
it will give you a brand new like high speed full speed blower motor once
again after you replace it . Usually the blower motor goes and it doesnt
even turn on but if its blowing slowly then its likely that you need a new
resitior for the blower motor and many times its right underneath or right
next to the blower motor.
richpin06a: The only difference on this year is that the high setting goes trough the
body control module on it way to the blower motor.There are only two fuse
boxes on the s-series.
farmerinchico: Very informative, thanks!
Bill Goodman: I am currently trouble shooting my sw1 blower motor as It stopped working
on me. I tested the connections at the motor and the ground was good, but I
was not receiving power to the motor. My fuse box is a little different
than yours, and it appears I don't have a blower motor relay... htt
p://i.imgur.com/2VwHfv7.jpeg I noticed the recirc fuse was blown and I
replaced that, but I am still not receiving voltage. Where else can I
richpin06a: Sounds like a bad ground or the motor is no good.
69RSZ: @69RSZ 14.7 at idle
richpin06a: Thank you for 411.
starcruise12345: Nice video. Got a question. I have a 1996 Opel Vectra. The ac blower only
worked if i turned the switch to highest speed ( 4 ). What could be the
cause ? appreciate your help.
INDUSTRIALIST1234: Great video. Please let me know the following. 1) What are the symptoms of
a faulty blower motor ? 2) Is it possible for it to affect both the a/c and
heating at the same time. Please let me know.
69RSZ: @richpin06a The dash is not working,but the battery reading is 14.71 at
ThePaulgregg: Richpin ROCKS!!!
richpin06a: You have a possible bad damper motor.Check out my video "Recirculation
Damper Motor Removal"
richpin06a: The lower fan speeds go through the blower motor resister before they go to
the motor.So i would start by looking at the blower motor resister.
Phil Ash: Hi, I have an issue with my heater/ defroster/ AC. When I turn it on
nothing happens. It doesn't work on low medium or high. I have rear defrost
but that is separate from the other controls and uses those lines on the
window when I press a button. Any guesses? I would hate to buy a blower
motor when it could be something else.
dlphoto: Here's a question. I have a 2007 Dodge Durango. I made it to the early
stage of this video where you check for ground. I didn't find continuity so
figured there's no ground. Any idea, where the ground should come from? I
put a jumper into that side of the plug and took it to ground and the fan
works. I wasn't sure if I could just permanently wire something in like
this or if there is an easy place to look to see why I've lost the ground.
richpin06a: It could be the motor is drawing to much.
Buick Mackane: Can anyone help with a 96 Saturn SL2 problem? Started my car today and
turned on the heater fan and the fan blows fine but I hear a clicking sound
from under the glove box area. I found that if I push in the "re-circ"
button with the fan switch on the clicking sound under the glove box will
stop. If i turn the fan switch on for ventilation, heat or for normal AC
the clicking under the dash comes back. Now I must drive with the
re-circulation button pushed in to get max AC with no clicking. Why?
dLimboStick: You need to change the title of the vid. You didn't even test the blower
motor. You disconnected the motor and tested the blower control circuit.
foxdmulder: thanks for your great videos.
Buick Mackane: Thank you Rich, I will check out your damper motor video and let you know
what I find when I start working on the car.
MrWill1985: @richpin06a What was your blower motor doing? My 2009 Ford Focus blower
motor works properly when I first turn the blower on but after 20-30
seconds later it stops working. My father checked it the same way you did
and informed me the blower motor went up. So I got one on order right now.
Do you think it is the motor? One source says it may be the switch. So I
hope I didnt spend $97 for nothing.
Rob Grode: I still cant figure it out. I have voltage at the blower motor, but it
seems low, like 10 volts, the switch seams to work(turning it up and down
makes the voltage at the fan go up and down, but never above 10 or so
volts. The fan motor is new, the relay is new, the switch is used but new
to me, and i'm down to the last thing the resister. My question is: If I
have LOW voltage at the blower motor, does that mean the resister bad?
Also, is there any way to test the resister before i go buy one?
1bygoneby2: On your video you keep saying check your current when actually you were
measuring voltage with your multimeter set to the DC range at all those
Tom Bonnema: I forgot to sign the above post Tom Bonnema
69RSZ: @69RSZ 14.7 at idle,dash was not working.
Steve Rose: really just need to replace current with the word voltage,not that big of a
deal. thanks for your help. I'm not getting a good ground and the voltage
shows up regardless whether heater is on or off. there is no air flow. what
does this mean? bad ground or bad resistor?
richpin06a: @MrWill1985 Sounds like you have a bad blower motor i have seen them do
what yours is doing.
ricflair0124876: i have a 2004 mercury grand marquis gs and my blower motor only works on
low speed when u first turn it on could it possibly be a bad switch or
could the blower motor resistor be bad and also my radiator fan is not
working the car ran hot and the fan never kicked on at any time could the
sensor be out in the radiator fan the fan is a 2010 if so is it better to
replace the sensor and fan altogether and if so can u do a video of a
replacement on how to do it thanks
richpin06a: No i did not see any insulation.
richpin06a: I would start by testing the blower switch.We can rule out the radiator fan
motor if it comes on when you turn on your A/C.I do not foresee a grand
marquis video in the near future.
AzureHoBo: Hey thanks for making this video, the other day my dash started to shake
when I turned the blower on. Looked at the fan and it was clogged with
insulation material. Did you notice any of that insulation above the blower
when you took yours out in your other video?
richpin06a: A bad motor can blow fuses melt electrical connections and make abnormal
bhavi45: Hi Richmond. Your videos are amazing. Iam an entry level technician would
love to watch all your videos. Great work highly appreciated.
dahoss65: I have 94 bonneville that I keep on high defrost. Recently, the blower
would be working & if I turned the car off & back on after a few mins, the
blower wouldnt work. Then all of a sudden it would kick back on. It done
the same thing today when I went to lunch. I started up the car (high
defrost was already set), to warm up the car. I turned car off & had lunch.
After 20 mins, i went to warm interior again(due to it's cold here), and
the blower wasnt working. It kicked on again later. Any ideas?
ricflair0124876: the radiator fan doesn't come on when the ac is turned on like it is
supposed to do
