Re: 96 blazer heating problems
After the engine has warmed up, touch the two heater core hoses going into the firewall. If one is hotter than the other, then the heater core is clogged and needs to be flushed.

Re: 96 blazer heating problems
Check/feel the heater hoses at the heater core.
If both are cold remove them from heater core and hook a water hose or low pressure air hos to the heater core and see if it is stopped up. I have had the clog up but if you can back flush them or get any water going threw it switch the heater hoses for a few days and see if that helps clean it out. If not you will need a heater core.
