Ok Guys, I need some help. My heater is not working at all. It blows air but it's cold. Top radiator hose gets hot and vent opens and closes. Is there anything else I need to test in order to diagnose this problem?

Disconnect and flush the heatercore, it is probably plugged up!! Use a garde hose.

Thanks. I finally got it finished. I flushed it and it works great. Any way to make it get warm faster?

No these old Jeeps take quite awhile to reach operating temperature but make sure you have the OE 195 degree thermostat installed other than that instead of sitting and idling drive it it will heat up much faster. Unless your in Alaska I would NOT block off the radiator as tempting as that might be.
