No heat in 97 blazer when the heat is turn on it leaks onthe passenger side and it steams up the window so bad


Hi without knowing the exact routing of the heater hoses, it seems quite obvious there is a leak in the cooling system to the heat exchanger (on the inside of the cabin). Generally you could find it behind the dash. Just an advice recheck the coolant level to avoid further damage before repairs are done.

Where is the heater core and heater control valve located at on a 1997 chevy blazer?


Excepting the Volvo, every heater core I have ever seen was in the heater box which has been behind the glovebox and above the passenger's feet. That is why when they leak the floorboard gets wet over there. Since the early 1990s they have been a *itch to get to, thanks to airbag technology and you are not going to be able to do this job without a repair manual, a good set of tools, and a free weekend. If you open your hood and find the heater hoses going back into the firewall, they are attached to the nipples on the heater core so the mystery is solved. While you are looking at the heater hoses, there could be a valve in one of them with a cable coming from it, that will be your valve.

Removel of heater core


If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

How do I take out replace the heater coil in my S-10 Chevy truck?


No you do not, I think you mean the heater core, because its leaking, first unhook heaters hoses under hood (there may be a clamp on the core tubes that has to come off), next go under dash on passengers side, take the one bolt to the far right under dash by the dome light, thats so you can pull the dash out just enought to get the cover off the front of the heater box, behind that cover is the heater core, now that cover is held on with about 6 1/4 inch screws give or take 1 or 2 when you get the cover off you will see 2 straps, one on each end that hold the core in place, there are 2 1/4 screws in each one, remove them and core will come out. Put back together in reverse order.
