HEATER CORE

1993 Ford Ranger

Heater problem
1993 Ford Ranger 4 cyl Two Wheel Drive Manual

we have no heat and was wondering where the heater core is located? Had it flushed about 1 yr ago and it was very corroded and it said online that if it went to the heater core it is malfunctioning. Had the thermostat replaced at the same time.

When you say no heat, do you mean you have air blowing but it's not warm, or you don't have air at all?

If you do have air coming out, make sure the heater core is the culprit for your no heat problem: with car at normal operating temperature and heat set on high, feel both inlet and outlet heater hoses under the hood. They should both feel hot. If one feels cold or much colder than the other, then your heater core is defective. But if they're both very hot, your heater core is probably fine.
Have you checked your level of coolant? Add some coolant if it's too low.
Also, can you hear the blend door moving inside your dash when you move the temp control?

Your heater core is located behind the glove box inside the plenum. Just drop the glove box, and unscrew the plenum cover, and your heater core should be right behind. Replacing the heater core on this year/model is an easy job.
