With car at operating tem. heater puts out minimal heat. It is luke warm if I keep blower on #1 setting. When put too #4 setting, it feals as if its cooling off. Coolant level is right. I tried a new thermastat, no change. Engine does not run hot and I do not have the issues of a bad heater core (smell in cab,water on floor,ect.) I almost believe its something with the dial and or ducting that allows the heated air to enter the cab. I see that this is all electronic and wounder if it is maybe a servo or motor issue. The blower motor works very good in all settings. It has an excellent A/C. What can I do myself to cure this outside of a mechanic/$500/ and new core. This has been "thier" answer to everything.

Re: Lack of heat
Sadly "there" explanation is probly correct, when you say you have some but not alot of heat on low and then almost non on high, that is due to a plugged heater core. A heater core acts as a miniature radiator inside your cab. When the fan passes the air by it it picks up the heat and blows that into the cab. While doing that it also cools down the heater core. The more are you pass by it the cooler the core gets. What you can try first before replacing it is a coolant flush. This will run a mild acid like sollution through your entire cooling system. Sometimes that alone is enough to let more hot antifreeze run into your heater core thus giving you more heat. Another option is to disconect both lines into your heater core from in the engine compartment and run a hose into one , leaving the other to drain out. Depending on how plugged it is sometimes you can "Flush" out the buildup this way as well. G'luck and keep warm!

check to make sure your cooling fan isn't running constantly, also if your temp gauge says the engine is hot but the heat isn't you have a flow problem. maybe water pump or a clogged/ crimped hose. if your gauge isn't very hot then put some cardboard infront of the grill.
when you put the heater on hot and the blower on full and the car is running at idle, the coolant in the heater matrix is cooled quickly,as when the radiator fan comes on to cool the engine, have you tried raising the revs and checking the heater to see if it gets hotter. If this does not happen you could have air lock in the cooling system and may need bleeding properly.
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
Check both heater hoses under the hood put your hand on each one and feel the temperature make sure the engine is warmed up to operating temperature though. If one feels hot and the other one is cold or luke warm your heater core may be plugged up also on those hoses see if there is a heater valve connected to either one if so make sure it is operating properly.
either the heater rad is blocked where someone has put a leak sealer in or the flaps are not operating properly,if the pipes appear hot ?? then i would be inclined to disconnect the pipes and try flushing the rad with a hose and reverse the direction of the water flow 2/3 times ,dont forget to refill with antifreeze
9 times out of 10 on this old of vehicle its the heater core. If your car temp gauge is working and the car is heating up fine and the blower works then it is most likely your heater core. Not sure how hard it is on that car. SOme times it just under the dash takes about 30 mins but some cars you have to pull the dash out. The part alone is cheap. I would try logging onto autozone.com put in your car find the part (heater core) then look at the how to change section of auto zone.
YES, THEIR IS A HOT WATER CONTROL VALVE, ITCAN BE OPERATED BY VACUMN, OR CABLE, VAC, TYPE WILL HAVE AVACUMN HOSE TO IT, PLS CHECK IT FOR CONDITION, CRACKS, SWELLING, IF OK, THEN WITH ENGINE RUNNING, HEATER CONTROL IN HOT POS. PULL HOSE OFF VALVE, PUT FINGER OVER END, FEEL FOR VACUME. IF THERE IS, MOST COMONLEY RESULT IS THAT VALVE NEED TO BE REPLACED.
