Heater core? Inlet or outlet hose fitting at heater core?
Heater core leaking?
Most likely a failed blower resistor.
It's located under the dash in the pass. side floorpan. Remove the screws that hold up the trim plate, that will reveal the bottom of the motor, it is removed like a twist-lock, 1/4 turn and it should drop out.
you turn it to the west
i need to know how to replace the heater core on my 1992 s-10 pickup
under the left front tire
Under the dash on the passenger side.
no you don't have to its actually like just the hoses and the blower is under the dash
Start the car, turn the heater/blower on full, The hose that is the hottest is the Inlet. The coolest is the Outlet.
take it to a shop and have them do it If it's the same as a pickup, take out the glove box and the resistor should be on top of the heater box. Not much too it.
