No Heat

[Sabre]

Hi
My friends 02 Jeep Liberty has almost no heat. When her air conditioner is unplugged she can get a little, but for only a few minutes. Any ideas on what's wrong with it? Any help would be awesome.

Check the coolant level. If it's low, top it off with HOAT (i.e. Zerex GO5, no universal stuff!) and then figure out where it went.

I had to flush my heater core to get our heat back. There is a good you tube video if you search. If I did it again I would cover the fuel rail and spark plugs on the passengers side with a trash bag. I was able to do it without pulling the hoses off the radiator overflow tank. I just moved it out of the way.
