I am doing this right now, and this is exactly what you need to do, but
there are 2 screws behind the inner passenger side wheel well. I had a
broken vent flapper door too. I think that is the reason i didn’t have any
air to the floor. I also replaced all the tubing under the dash and a bad
actuator. I have been working on this all week should hopefully be done
today. New radiator new water pump new heater core new hoses also. I am
not going to put those inner wheel wells back rusty so i cleaned em up an
painted em . I was going to do the timing chain and sprockets as they
recommend that on a new water pump. This is a good instructional video
which i wasn’t able to really find any on here. It really is a pretty good
size job but i will be glad when its all over and the heater is working
great….
Hi my car is a blazer 98 and the problem is not blowing hot air i ready
change the termostate ,blower motor resistence and the heather control what
go inside and nothing change can you told if is necesary change the heather
core? Or just any sensor thanks for you help
Thanks for the Help!
i just changed the heater core in my 95 s10 4.3 z vin, it was a bitch.
ended up not completely removing entire dash assembly, just removed the
bottom sections, lowered the steering column, pulled the upper dash off its
hinge points, all used the steering column on one side to hold up the
dash, and a jack stand on the passenger side floor to hold it up on that
side, reached up around the dash to remove heater assembly cover, and the
core is rite there. just pulled the hoses off the outside, took off those
lil brackets and there ya go. a lot easier then disconnecting even more
wires. fortunately mine didn’t have the security bs to deal with since I
changed out my factory head unit. total deal took about 4 hours. just be
careful to reconnect everything u take apart, and if you don’t tighten the
screw in your main wiring harness under the driver side dash bored..
nothing will work.. I found that out the hard way and about shit a brick.
also be sure to disconnect the battery before doin any of this.
thanks most you tube vids are a joke you must know what your doing
Just switched my interior from tan to charcoal, could have done the dash
without this!!!!! Thanks man!
How did yu get your blazer off “security mode” because I kno it had to lock
the engine when taking off the security wires?? I need to kno
.

There is a couple more screws on the 2002 Chevy blazer s10 under hood on
the back fire wall. There is a a bracket with one on each side and the one
to the drivers side i took a 10 mm wrench and broke in half to get out with
open end. It is a pain but The whole job is a pain. The video did help a
lot though
Hi my name is Joe What is your question,at 2 min 14 second, I will glad to
answer
Thanks alot!!! It helped me replace mine.. I wouldn’t of been able to
replace mine without this video
Did you ever run into a problem where the heater blows nice hot air just
not on your feet? my S10 will not allow me to blow air to the floor it
gives it a try and then diverts to defrosting the windshield any help out
there?
Hey you good man!! Thanks for the help !!
I’m 100 percent agree with you on everything you said. If you do not like
the music, simply lower the volume or mute the video. ☺
Appreciate the video! The hardest part was putting everything back!!!!
Antifreeze odor inside that fog the windshield
Thanks so much for posting this video. I was able to replace my heater core.
Thank you for the video is this the same process for my 96 s10?
How long does the whole process take..From start to finish..Great vid…
@EricTheCarGuy I just completed a replacement and the whole job took 10
hours. I am glad it’s done. I drilled the hole in the black box like you
showed and that was a great tip. Thanks again and if anyone is
contemplating this, you need not remove the dash completely as it pivots
down far enough and you can leave the heat/air box in as well and remove
the core pretty easily. I sold this truck and the core started leaking, so
this was a freebie for the buyer. Core was $43 bucks on ebay
It’s amazing what you have to go through for such a small part sometimes.
Thanks for posting this I thought it was really good.
@Izzyman49 You are right and make sure that you don’t miss any connector or
screw
well say … Lol
I hope this video has helped you, that’s what counts Thank You for comment
This video helped out a lot
Great Video. I just finished doing my truck with the help of your video. It
only took about 5 hours too! Great reference tool. I came back to it a few
times during my work. Thanks!
Took me 8 hour but I take my time….. Thank you for your question
enough said
what were the symptoms? i am afraid ill have to do this with my eclipse
Hi Joe. Sorry to take so long to thank you. Getting ready for Christmas,
y’know. Did the job on 12/8. Took us 10 hours-5 hrs to remove dash, 10.5
seconds to swap cores, 5 hours to put it back together. Your and others’
videos made it much simpler than going into it blind. Thanks so much for
taking the time to post your experience and tips. Could have done it
without you but it would have been a bear and total misery without your
help! Thanks & Merry Christmas to you & yours!!
The job by himself is difficult and try to change the heater core without
pull out the dash make it more difficult, that why you see at 3:02 the dash
out. I hope this video helped you, (☺‼ Thanks ‼☺)
