I am having a temperature problem. My car has only luke warm air. I have also noticed that the temp of the car normally runs at around 200 degrees and it is now only running at 150 degrees it does not fluctuate and the coolant is full. possibly a temp Gage stuck open? Any ideas? Thanks J

Hows the engine temperature? if its stable and not fluctuating, 195 degrees or so, suspect maybe a partially plugged heatercore. if so, maybe try having heater core flushed first to make sure it improved.

If you smell coolant , there is a leak. I'm leaning towards a leak in the heater core if no fluid is visable and you smell it.
Pull the blower motor off and look inside to see if it is wet.
Have you had any issues with the radiator in the recent past? Maybe tried to correct it with stop-leak and didn't open the heater to full on hot? (maybe clogged the heater core up?)

No heat blowing cold air.


Do you smell coolant inside of the vehicle. If so then chances are your heater core is going.

One of two things has happened. Either your coolant has gotten really low (easy enough to check) or you heater core is starting to plug up.

2004 CHEVY SUBURBAN FRONT A/C WORKS BUT THE REAR DOESN'T TURN ON


There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

Hi, the likely problem is a bubble forming in the system, possibly due to a head gasket failure.

Try stopping on a steep incline--does the heater stay warm? If yes, what you have is an air bubble that hangs at the heater hose until pressure from the water pump blows thru it as the engine speeds up. Park on an incline, open the radiator cap, run the engine until the thermostat is open, turn the heater on, crack open any/all bleed ports to release any trapped air, and fill the radiator to the neck. Wait until the level stops dropping and make sure bubbles don't continue to come up. If they do, you may have a blown head gasket that will keep forming these bubbles until you change the gasket.

2004 Dodge Intrepid heater problem


This sounds like your automatic climate control is starting to malfunction. Check to make sure your coolant is full, and temp is not fluctuating, and when your vehicle is warmed up, try using the low setting and feel for air temp. Is it warmer than if you turn it up? When at idle the vehicle is not producing heat the same as if you are driving, putting load on your engine and more air/fuel combustion means more heat, which is why you can feel heat while driving. Ideally you should feel heat as soon as the engine is warming up, getting hotter as it reaches peak temp of 190-210 degrees. You can try to make sure your water control valve is not blocked, and all electrical connections are secure. This will be located close to your firewall and connected to the coolant tubes that run into your firewall to your heater-core. Also use recirc (setting)to try to summon as much heat as possible, however ultimately, you may need to take you vehicle in for service. If it only warms when driving defrost will be an issue. Good luck.
