1-your thermostate is stuck open half way. thermostate is a simple device that made of enlarging metals when heat is applied. it suposed to be in close position to allow engine heat up, when specified temp reached it opens and let it flow and radiator tries to keep coolant cool.when it is broken it stucks or it acts slow or it wont acts at all. in your situation it is stuck open half way. it allows enough water to be heated but flow is limited to heat cabin heater.
2-if there are cabin heater selenoid/selenoids for two different temperature for cabin left and right, on some instance those selenoid valves to adjust cabin heater stuck open or closed like thermostate acts on first case. so heat is not enough to heat up cabin heater.
Ihave a 2000 Dodge Durango i have put a new radiator and the gaskets came back good um i replaced the coolen fan also the thermostate and tested it it it came back good when i run it its fine but when i am in line its hot when i drive it cools down........
Sounds like it could be the thermostate, or the water pump? Or the radiator stopped up. Can you see water working and moving around in the radiator with the cap off and motor running? You can check thermostat by placing it in water on stove and turn heat on high. It should open up right before the water starts to boil. but it is only ten fifteen dollarsl. May as well change it anyway.
The water pump has what's called a 'weeping hole' built into it. If the pump is bad You'll se water coming out of the hole. When was the last time you flushed the radiator? It may be your radiator cap is bad, they should be changed once a year & the radiator flushed. You can also test ur thermostate. take out ur thermostate & put it in a pot of water so that the water covers the thermostate. Then put a cooking thermometer in the pot to & heat the water til it says 195. u should see the car thermostate begin to open. if it don't it's bad & needs replacing.
checked for loss of water? and check oil for tan color
indicating a water /oil mix .
any white smoke at the tailpipe?
and last maybe thermostat sensor is connected with no shorts.
CHECK WATER LEVEL CHECK OIL LEVEL IF NO WATER FILL UP AND IF WATER DISSAPERS OR TURNS MILKY YOU HAVE A HEAD GASKET PROB CHECK WHILE RUNNING BUT DONT GET TOO HOT
ONe of two things,your thermostate has gone bad or the water pump is bad. Regardless if your are going to change your water pump, it's a goos thing to change your thermostate too. Good luck. The water isn't that hard to change on the 3.4 but the thermostate can be a pain.
