    When engine is cold the temp gauge is low and fan is always running never stops. After engine is hot the gauge will go from normal operational range to low with the temp going from hot to luke warm. The inside temp slide is set to the maximum for hot heat. The fan never stops running.

    Everything is the same whether in the defrost mode or the heat.

    Fan never stop running while in the heat or defrost position. Also when I slide the temp lever to cold the inside cabin area goes cold just like the switch reads.

    Motor 1258, I checkedthe power distribution panel underhood for radiator fan relay. I found a/c Wot relay, Fuel pump relay and E E C Power relay. Removed all three one at a time. The fan blower did not stop. The rest were fuses listed as following EEC power,Fuse pnl, elec shift,fuse pnl, and 60 ign.

  • djb1sab Jan 24, 2009

    Yes, One reads EEC Test. The other one I unplugged and fan motor keep running.

  • djb1sab Jan 24, 2009

    Should I be checking that and if so what am I checking for.

    Check your rad fan operation, is it staying on all the time when engine running? How does it react with temp gauge, for example, does it come on before temperature says normal? Shut off only when it hits cool, or low on gauge?

    overheating. replaced thermostat. radiator and reservoir holding water and heater blows hot. running heat was keeping it in normal range but this morning it red lined with heater blowing full blast

Double checking, does fun shut off when switched to heat instead of defrost?

    Check power distribution panel under hood for rad fan relay. Give it a tap with handle of screwdriver when gauge reads cool, and see if rad fan shuts off, or remove it, and see if it goes off to confirm you have correct relay.

    Does yours by chance have any electrical connections on side or back of rad, ? I'll do some checking.

    Coolant temperature switch must control that. Front of engine near coolant outlet.

No heat 98 ford f150
verify heat is in normal range using dash gauge. if its normal then good. if it is below normal, you may have a sticking open thermostat not allowing heat to build up enough for "hot" heat. but usually luke warm heat will be this issue.

If everything is fine with gauge heat, check the hoses going to your heater core with your hands. they BOTH should be hot. If one is hot and another is warm then you have heater core issues. If both are HOT then you may want to check your temp controls. either temp control may not be working or the door that changes temp may be stuck in the cold position... there are many things, but checking the heater core hoses are most likely going to reveal bad heater core.

You will need wiring diagrams and volt meter to diagnose anything other than touching hoses and looking at gauge.

Heat goes in and out and the temp gauge goes up and down
Your temp sensor has nothing to do with your heater. The temp sensor needs coolant in order to work properly. So first check the coolant level because if it is low your heater will act the way you describe. Once the coolant gets low enough the heater will blow cold. Another possibility is the radiator cap. After the engine has warmed up it expands when it cools down it contracts. As it is contracting if the cap is weak air can be drawn into the system and cause air pockets to form and will cause the same problem

1993 ford escort heater blowing cool
heater core cloged, get car hot check heaterhose going into heatercore should be two inch thick hoses going into the heatercore, underhood against firewall pasenger side, after hot while running heater on, chech to see if both hoses r hot, if one is cold,that means there is a restriction in the heatercore, sometimes on older cars there is a external valve run by a vaccume hose, or cable, thats fixed in with the heater hoses , sometimes this valve jams and can be manually switched.

2003 dodge durango front heater will not blow heat. but when driving heat will slowly come throught the heater vents. what should i check?
Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.
