To replace the heater core in that model truck you will need to remove the whole dash, steering colum. Then discharge the A/C and remove the heater/a/c case. It is a time consuming job and difficult without the proper tools and info. If you are going to attempt this then be sure to disable the air bag system by disconnecting the battery for at least 10 min. before you start working. Good Luck

The heater core on this truck is buried under the passenger side of the dash and is a very complicated thing to replace. It must be done or the coolant will run out and the truck will overheat. Use a reputable shop and plan on being without the truck for 1 to 2 days.

To replace, you must raise vehicle, detach both hoses running to heater core by firewall. Than on inside, you must remove bottom console, than remove plastic heater core cover without breaking, remove metal strap, remove heater core.

Heater blower went out?


Either the blower went bad or the heater relay went bad. This does not sound like a heater core problem unless you where smelling a SWEET smell when it was running.

Not sure how to get to Heater Core in 01 Chevy Blazer


Their is nothing either quick or easy to changeing a heater core. Most have to have all of the duct work from the AC and heater under the dash removed. The two hoses for the outside of the cowling to the core have to be removed. Some even have to have the floor board matts removed to have enough clearance  to take out the heater core. A really rough job.
