Angie Reed: My 2005 chevy trailblazer makes a whistling noise when driving when ac is
on. There is no noise when vehicle is idle and none when heat is on. Any
clues? Thanks in advance
carpe diem: The heat does not blow out on the driver side of my 2008 trailblazer .
Passenger side if fine but not driver side.. Can you tell me what it might
be? One side works so it doesn't seem like it could be the blower
motor? You know best
Sharon Stribling: ok my blower isn't blowing cool air no more but it clicks on, what else
could have cause it to stop?
Dawn Jones: I have a 2003 trailblazer that the ac and heat work fine but when i turn
them on It makes a clicking sound on the passenger side vent? Is this the
blower going out or something else?
Keirria Mosby: I changed the motor wires r good but heat still doesn't blow I here
something when I change to vents an floor still no heat wat should I do
Steve Young: For the fan blower, Are you replacing the fan blower or the parts that
connect to it, because i am having that problem my air/heat dosent work and

problem? i have a chevy trailblazer 2005
521farmer: howdie why does my blower motor only blow cold air in the rear ?hot air up

Shellhouse58: can you replace this part without the rubber hose or is that a must have?

1A Auto Parts: You may want to check to see if the AC system needs to be charged. If it's
fine, usually when the blower motor resistor goes, you'll start to loose
some of the speed settings. We carry them on our website for all kinds of
vehicles. 1aauto.com 888-844-3339
1A Auto Parts: You may want to fix the wires and plug that had melted. Usually a bad
blower motor resistor will cause this to happen. 1aauto.com 888-844-3393
Sellemt: What is the troubleshooting procedure to determine whether or not to
replace the fan speed unit or the blower motor? 2005 trailblazer and can

vagrantus: Thanks for this.
Paul Kairouh: thank you for your reply have a nice day
Joe B: how do you change the sensors resisters i think are bad??thanks JOE
Stanley Ross: If my air blows hot on one side and cold on the other, could it be the
blower or something else?
jeb065: Thanks for your videos. You do an excellent job with your videos.
JAntrim: what is the yellow plug under the panel?
1A Auto Parts: There could be an issue with the blend door.
1A Auto Parts: They may have meant to change the cabin filter if your vehicle came
equipped with one. They dealer can run your VIN # for you and tell you if
it did, as well as it's location. Hope this helps you out. Have a great
day! 1aauto.com 888-844-3393
1A Auto Parts: It could be the blower motor resistor of the blower motor. If you started
loosing your speed settings and then finally lost the air coming through
the vents altogether, then it could be a bad blower motor resistor. We
carry them on our website 1aauto.com 888-844-3393
1A Auto Parts: It could be that, or you may even want to check for a loose wire that might
me causing it to turn off and on.
Paul Kairouh: Hello I have a trail blazer 2006 causing A/C smell after 10 minutes,someone
told me to replace the A/C filter,do you know where is located? could it be
a clogged drain pipe? also location of it please , appreciate it thanks Paul
Zain Bryant: My Ac or heater doesnt blow at all. Is it the blower motor that needs
Suhail Schaffer: Hi, I have an Envoy XL. My air works perfectly in the front but not in my
back seats. It blows air when it wants to and when it does I can't control
the temp of the air or the speed. I'm assuming its either the speed
controller or the fan blower resistor which I'm assuming is in the middle
console. But I have no idea how to access it.
1A Auto Parts: @litho1960 We currently do not have an auto repair video for that
particular repair. If you happen to have a Haynes or a Chiltons auto repair
manual it should be covered in those manuals. Hope this helps you out.
Michael Engle: this is great! I do have a few questions: 1. on that kick panel, do you
know what that yellow connector is? My truck has one side of that connector
but it's not connected to anything else. 2. My fan motor sounds ok and
blows ok but the connector to the blower resistor has slightly melted. Is
it at all possible that the fan is fault and has caused this? Thanks much!
1A Auto Parts: You may want to check the fuses first to see you have a blown fuse. Then
check to see if there's power to the blower motor (if the fuse is good),
with a test light or an ohm meter. Hope this helps you out. 1aauto.com
