1st check the coolant level to make sure it's ok, low level can result in insufficient heat. What is going on with the engine temp? Is it running on the 'cool' side or normal range, in the normal zone, or running hot? If it is on the low side of normal, you may need a new thermostat. If the thermostat sticks open, the engine won't reach operating temp, and you will have minimal heat.

The heater on my 98 ford expidition blows hot air at first and then blows only Luke's warm. If I shut heat off and turn back on it will blow hot and then turn Luke warm why


-Sounds like the system is clogged or the on off valve is not open
properly.
-Check the valve and flush the system. It should be good to go.

Good luck

98 grand cherokee little heat.heater hoses hot top rad warm bottom is cold collant barely luke warm


While it doesn't seem likely, if you've changed, or had the thermostat changed.... I'd say you got a faulty thermostat. I am curious as to what your temperature gauge says the temperature of the engine and coolant is.. If your gauge is showing hot, I can think of two more possibilities... the water pump isn't pumping right... and, if the water pump isn't working right, the problem can be a cracked head or block, which can cause an airlock in the coolant system. Check the coolant or radiator cap.

Check the return line on the heater core. If its not warm or hot, the core has a clog. Will have to be replaced.

Mercedes 190E heater blowing just luke warm air


there should be an electric water pump exclusively for the heater. on these 201 body cars it should be under the hood, on the passenger side,near the fender well. when the heater is engadged, this pymp should turn on pushing the hot water into the heater core. if these are not working, it will obstruct the water flow.

Fluctuating engine temp a/c sends out cold air intermittently


Here's the thing. The ECU will shut down AC if the engine temperature is too hot. If the coolant temperature sensor is malfunctioning (lying to the ECU) telling it that the temperature is hotter than it actually is, the computer will turn the AC OFF.
