No heat coming from the heater. Just cold air blows when turned to heat. AC works fine.
Don't know if this could be related but we've had a problem with the van going into passing gear. At times it will just refuse to get out of 1st gear (it is automatic) Usually letting up and down on the accelerator will "fix" the problem and it will go ahead and shift into a higher/faster gear.
In trying to fix the acceleration problem we've changed the water pump, among many other things. Van isn't overheating or anything.
Any ideas? Sure do need that heater.

this sounds to me as a vacuam problem ...look at your intake manifold find vacuam tree were vacuam line all connect togather look at ALL vacuam lines ...because heating systems and transmissions initially are actually controlled by vacuam good luck

I'm real sorry that most people that answer your or anybody else’s questions, know very little about what their talking about. ie..
Magikmann: says no cooling in cooling system, well if this was true your engine would have melted by now and doesn't relate to your symptoms, restricted heater core would still produce some heat.
bowhunter...,nomad8908, Thermostat? are you kidding? the engine would take longer to warm up and to produce heat for the heater core, but would not stop from making heat at all, this still doesn't relate to the symptoms.
danny n ; is on the right track but fails to give other options to look for.
My suggestions for diagnosing your symptoms are... for the transmission, most car's have what's called a kick down cable attached to the carburetor or throttle body linkage and an adjustment of this cable will in most cases solve the shifting problem.
The vacuum system can affect the transmission shift pattern as well, their is a vacuum switch near the rear of the transmission that controls shift points. As danny n suggested, check your vacuum system for leaks and cracked vacuum lines.]
As for your heating problem, the vacuum problem can affect this system as well by not opening the dampers and vacuum actuated doors under the dash. Also some older vans have a cable attached to the temperature control lever that goes to a valve on the heater core line in the engine compartment, this cable comes loose and the valve can stick, check the cable if so equipped under the dash and engine compartment.

No heat conditions are caused by a number of things such as, bad thermostat, low coolant level or air pockets in the block, defective heater control valve, blender door inoperatable, and a clogged heater core from not being used during summer time. You can backwash the heater core to try to unclog it. Gently remove the 2 hoses from the heater core under the hood. Force water with a hose inside one hose and watch if any sediment comes out. It should run clear. If you see seditment, then go back to the other hose and repeat the process back and forth until clear water runs through.
Good Luck........

Check your Thermostat. If it's not regulating coolant right, it may cause the hot air to maulfunction. The transmition sounds like it can be going. My pap's Pontiac Grand Am was acting up the same way. It refused to shift and such things as you discribed in the shifting pattern. His trans was going. He still needs a rebuild. What it might be, before you get any kind of repairs. Check your transmition fluid. If it's brown, it's bad fluid. This can cause the tranny to stick or slip after a while. If the fluid is light or dark pink, it's okay. If it's brown, take it to a repair shop and they can strip your fluid, change your tranny fluid for about 50 - 70 dollars tops. Average price is about 30 - 35 dollars.

There is a small black vacuum line that runs over the engine and it breaks all the time. See if you can find it and repair it but make sure you reroute it away from the engine.

try changing the thermostat might be stuck open or the door actuator motor might be bad for the blend door in the heater control box

no coolant in cooling system, restricted heater core (common problem), Blend door nor working.
related to trans problem, probably not

Vacuum, vacuum, vacuum. Check all vacuum lines.
