If the heater hoses are not hot, it could be a blockage in the system or the thermostat may not be closing when it is cold. The block and components are probably rusting from the inside out.

SOURCE: 2004 chevy subarban blows cold air on one side hot air on other side

i was a GM mechanic for many years, the problem you are having is one of your mode door actuators has gone bad, most of the time it is the actuator on the drivers side that causes the problems, i have seen this many times, sometimes you can take it to the dealer and they can hook the computer up to it and recalibrate it but most times it has to be replaced , it is located under the dash in the area above your gas pedal.

SOURCE: heating doesnt work - no hot air in chrysler grand voyager

(check water/ antifreeze level first, make sure it's full, low water can cause it not to heat properly) it could possibly be either the thermostat- fairly cheap and easy to fix, great for DIY's- if that doesn't fix it, it could be heater core.

REMOVAL & INSTALLATION


See Figure 1



0996b43f8020d980.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 1: Plenum door vacuum motors

  1. Disconnect the vacuum hose at the motor.
  2. Remove the 2 motor attaching screws.
  3. Rotate the assembly so that the slot in the bracket is parallel to the tee-shaped end of the door crank arm, and pull the motor and bracket off the crank arm.
  4. Installation is the reverse of removal.
--- Search for other vacuum motors under the dash to see if the vacuum hoses have somehow deteriorated or become detached. --- Try to look up your vehicle on autozone.com for other vacuum motors under the 'heater' section of the 'chassis electrical' section of the 'repair guide' after selecting your 1996 Ford f250 crew cab vehicle. http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?pageId=0996b43f8038ebd8

Ok,I have a 2002Firebird 3.8 seriesII, V6 coolant/water is coming up from radiator with cap off.


When you change antifreeze an air pocket is created in engine behind thermostat. You must let it run until the thermostat opens. Until then, liquid will boil backfkowing through bottom of radiator.
As for milky look, blown headgasket would cause white foam that if left alone wouldclear up. Otherwise it could be an additive in the fluid such as rust preventative.

is the engine fan coming on? , when the heads were removed ,were they pressure tested. u may need to use a carbon block test from the coolant tank. the liquid will turn a different color if exhaust gas is present in the coolant,which would be a internal problem

Cabin Heat is Intermittent / Fluctuates / Cycles


You may have air trapped in the lines to or from the heater core.
If you (still) have a real radiator cap on the radiator, remove it with a cold engine, start and run the engine allowing it to warm up while watching the water/coolant level. Make sure the heater control is set to its highest heat setting while doing this. If it is trapped air, you may see it 'belch' after the engine is warm and the engine thermostat is open. Refill as needed if this is the case.
It's more difficult without direct radiator access and may require several cycles of hot/cold to allow refilling through the overflow.

Will varying temperatures affect the rate in which metal rusts when submerged in different liquids?


yes rust or iron oxide is formed when iron (Fe) reacts with the oxygen (O2) in the air and in water. the more oxygen the faster it will rust and since cold air is denser than hot air it could be said that metal will rust in the cold much faster. however once freezing point is reached the o2 in water cannot react with the iron and therefore is a nonreactant. only the o2 in the air would react so below freezing the process is slowed considerably. the liquid would affect the rate at which rust forms because of the water content in the liquid. if you submerge a screw in oil you could leave it indefinitely and it would not rust because there is no O2 whatsoever in it. whereas if you left it in apple juice the water in the mixture would eventually cause it to rust.

if your looking to keep somthing from rusting a coat of oil or wd40 then wrapped in plastic wrap is your best bet

My 02 town & country blows cold air and run hot


Check the coolant level and thermostate. Also check if the water pump is running. Also check/replace the radiator cap (ask for recommended one). Also check the coolant color (ENGINE SHOULD BE NOT RUNNING AND COLD, NOT HOT). If you see it has rust pieces in it (not orange as the usual color of DexCool used for GM vehicles) you might need to do the radiator and/or cooling system flush.
Good Luck

No heat in my 1999 ford taurus


Those cars were also notorious for the turbines rusting off the back of the water pump causing poor water flow. When the car has been running check the upper and lower hoses to make sure the are both warm. If the cooling system was in very poor condition before this work you may also have a plugged up radiator. Keep track of your coolant level for blown head gasket. Also check your oil regularly for milky color. This is a sign of coolant getting in to oil.

Heat (or lack there of)


The heat source for the fan is probably comes from the liquid coolant in the radiator. Since the temp gauge shows it to be warm, my assumption is that there is no hot liquid getting to the heat element in the AC/heat plenum.

Do the controls feel any different than they usually do? I'm assuming you have probably been using the system in the AC mode during the summer. I would try to see what happens when the different heater controls are moved. Somewhere there is a valve that is not being actuated, or a vent door that is not moving. My experience (personal) is that a door that controls air flow is not operating and that's because it has sat in one position all summer. Sorry I can't be more specific.

Hope this helps Good luck Loringh
