the heater core is located under the dash on the pasenger side behind the heater fan
The 1996 Geo Prizm heater core is located behind the kick plate on the passenger side of the passenger compartment. The kick plate will need to be removed in order to view the heater core.
You cannot fix or repair a heater core you must replace the complete unit with a new one...........
A good chance you have a faulty heater core
it should be below the radio in the heater box . must remove entire dash
Bad heater core?
Your heater core may have gone out. Or you could have build-up in the lines.
It's located right behind the tank for the headlight fluid.
Check the fuse first. If the fuse is good, check the wiring. If the wiring is good, my guess is that the fan has to be replaced.
Check coolant level? Bad thermostat? Heater core airbound? Temperature control cable not adjusted properly?
Yes.
Hey Rob==This is a pretty good job. Get a manual on your car from the parts store and it will have pictures and everything. Good luckJoe
