No heat in '99 XLT

[dannymack]

Hey All,

I am stationed in North Dakota and I have no heat in my '99 XLT! I replaced the thermostat thinking that would fix it, but to no avail. If anyone has any suggestions as to why I am still freezing that would be great. The engine is a V8 302 5.0L. Thanks in advance.

Is your cooling system working properly?

It could be the bypass valve, air in the system, or a clogged heater core.
