Also Check the Switch it could be bad. Good Luck and Remember.
Change Your Mind, Not Your Oil.
Use the First In Synthetic Motor Oil's.
See My Bio For more information. Check fan motor and wires. If the fan is not running, then it is either a blown fuse, defective blower motor speed control switch, bad blower motor resistor pack, or a defective blower motor. If the fuse is good, the odds are the Resistor Pack is bad.
how to replace a heater core in a 1997 Chevy blazer
were is the heater relay on1996 jimmy?
Same as a 96 blazer go here.How_do_you_replace_the_blower_motor_on_a_1996_Chevy_blazer
Behind the dash assembly, big job for the faint at heart.
your heater core is going out, you need to replace it before it ruptures.
Thermostat stuck open, clogged heater core, heater flow valve not functioning, or low of coolant.
To many steps to list here, would recomend purchasing a shop manual if you intend on replacing that heater core yourself.
It can be that your coolant level is low, your thermostat is stuck, the actuators are sticking...
Check the thermostat, also there could be a heater core issue...
