I just bought my heater core for my 1997 Ford Explorer 4x4 Sport for $60.00(Plus Tax) but I was Surfing the web and found that you can order it in line with SPI or STANT from $29.00 to 32.00 plus shipping. Good Luck
Very time consuming job. It takes what it takes.
I was just quoted $700 from a mechanic who does work on the side.
It should be the same as my 1995 - at the firewall the heater hose nearest the drivers side is the inlet hose to the heater core
Depending on the size of the heater you can purchase them from $10-150 at your local store.
Replace Heater Core
Try looking under the dash just below the heater core box on the right hand side. The switch should be mounted below the heater case. I have a 91 Ford Explorer but the 91 - 94 Explorer's are the same.
Yes, replacing the heater core should slove the problem.
Regulators are usually not repairable. You should replace it.
$800
