I wanted to add that even though the heater core's small tubes will get clogged there's still bypass where the coolant can go around, but this wont allow much heat to actually get pulled off the heater core for the heating system of the heep. So a flush might seem like the heater core is in good...

I did come to a conclusion.. well though it'd be a good idea to still do the flush and Tstat, a jeep guru in my neck of the woods confirmed that most likely it's the heater core. He explained that they are not like you're average GM or Ford heater core, they actually have very small tubes inside...

The heat sucks right now, never would have to turn it down.. The passengers always blows cold when on vent.. its not that no air's coming out, it just freakin cold.. ughhh

Well, the heat's now luke warm again not hot like it was the other night. Although it could be due to the temps being -1*F here. Still the mix hot and cold situation with the vents. Its not a dropped duct since the vents are still blowing air through, it just is a temp problem. It gets to...

So, I just pulled someone out of a 6ft deep center median ditch and I think I realized something. at some point in the midst of things I was head on up the hill at about a 45* angle. After pulling out the Grand Prix I stopped at the gas station since I needed gas and to fill the washer fluid and...

Im not 100% sold that the blend door is broken since I do have control over heat and I can watch the actuator motor on the bottom doing the sweep.. It does change the temp at the vent, just not super warm. Also I dont see how the blend door would explain the split vent heat (drivers side warm...

Blaine, that seems like a stupid coincidence since the thermostat only regulates the engine getting up to temp and helps it stay in the correct range.. So you're saying that after going to a jeep thermostat your heat was good?

Blaine, it doesnt seem to matter.. When I bought my jeep, the previous owner told me that he did the waterpump/thermostat. I could tell he had since there was blue rtv everywhere.. After noticing no heat and it sucking, I decided why not buy a 195* thermostat and change it just to make sure it...

The electric motor for the blend door you speak of is on the bottom of the heater box closest to the radio on the passengers foot well area. I am also having the same issue.. It gets luke warm in the jeep, but Im also having a warm on drivers side/cold on passengers side issue as well.. I love...

EPA actually now says that its fine to dispose of coolant as long as its diluted a certain amt. Im not sure how much though..

So my '99 4.0 NP231 doesnt show up on the dash when its in 4wd.. is this normal? I know the shifting into 4wd and such works fine since its snowing out here and I can see that it works.. but no lights.. is it just a sensor Im thinking?

anyone else with ideas?

snap on makes some really nice pics quite small should be enough to get in there and pull that bastard out.. Hope she felt really bad and paid you back (without money)

As I stated.. The problem isn't it getting hot enough. I disconnected the vac connection and they seem to be doing their jobs as well. Thanks for the idea
