If it is anything like the s-10 you don't need to remove the dash. I just removed the plastic cover that surrounds the heater core and removed all the heating vents and things that got in the way. I also took the glove box out to get to some of the screws. The hardest part with leaving the dash in is removing the heater core plastic cover but it can be done.

Bagged1984S10,

are your experience based on replace of an 1984 heater core.

I found these pictures on the web.
Is this necessary to tear down the whole interior.

you will be much better off getting a haynes or chilton manual so you can have it with you in the truck while you are working on taking the dash out. There are a LOT of screws to remove and some are hidden quite well. there is also a lot of wires to disconnect that should be labeled before they are unplugged so you get everything back together correctly. Also if your blazer has air bags be very careful with all the sensors. you definetly do not want the airbag to go off while you're working on it.

J_Sin,

I am living in Germany, I cannot go to Auto Zone and buy this manual. I might be the only blazer driver in the area of 100 miles.

Maybe you can help with some procedures.

Hello is this the correct procedure for a 1997 blazer heater core change.

What are snap on vent

· first remove speaker panels top of dash, then remove screws underneath.

· remove snap on vent on top of dash remove those screws also.

· take off all plastic covers at floor under dash.

· there are two bolts one on each side under sides of dash, remove them.

· now the steering column bolts are I think 5/8 you will have to remove these there are two of these.

· now when you take these off the dash will lower.

· under the R/S and L/S of dash you will see where the dash sits on hangers lift off both sides

· and you should be able to get to the heater core cover,

· remove cover and you will see core, there will be two core holder clips over the core.

· remove these, make sure hoses under hood are off heater core pipes or the core cannot pull out.

I wish I could help you out but I cant get my printer/scanner to work with this computer. I will keep trying to get it to connect and if I can I will scan the pages out of my haynes manual and post the pictures for you to use.

that looks like a decent write up for doing the work. BUT if you have delco loc II on your stereo make sure you disable that, then disconnect the battery before you start taking the dash apart.
