Don't know if this will help but a lot of cars and trucks have an auto run for the ac if it has been off awhile and not used. This is so the ac will not malfunction from non use. Could be trying to run this cycle..... takes 10 min usually or it could be stuck in that mode

Even with a fully charged battery i need to use a battery pack to start the van when it does start the cooling van comes on for a minute then goes off and that continues


Check rear AC in van and turn it off. Most vans have dual AC. Even if the front AC is off, the rear is still usually on and some vehicles have the cooling fan and condenser fan run together to help with cooling. Check relay and fuse also.

E150 van overheats


You have to bleed the system. Not very likely an air lock, since air will come out of the fill bottle sooner or later. You can try removing the rad cap (when its cold) start it up. put heater on high, let it run and check for good coolant flow in the rad. Any trapped air will also come out.

Heating system


I'm quite certain what your problem is. The fluid level is too low. Now wait, it's not that simple. In order to bring the coolant level to the correct height on this vehicle, ready for this?, You have to jack up the front of the van or drive it to an upgrade that is quite steep. The reason for this is that the heater core is almost a foot higher than the level of the radiator. I found this out by trial and error. Most dealerships don't evn know about this. I'm assuming you've already ruled out the easy stuff such as a bad thermostat or radiator correct? Let me know how you make out, okay? Thanks, Dana.

Cooling system problem


well it might overheat because air got into system, replace the thermostant and then fill system, run van keepin an eye on the temp, it will start to run hot because coolant has not filled the motor just the radiator, when it starts running hot shut it down, wait 3 minutes and start, now this is done with cap off,after restart coolant should get sucked in get filling radiator as needed,may get messy but got to bleed cooling system. hope thius helps.

2004 Odyssey, heat and A/C do not work unless van in motion


Since warm air eventually comes out when the vehicle is in motion, you may have an air mix door that is stuck in fresh or is somehow blocking warm air from the heater core.

To see if the air mix control motor is bad, you need to retrieve your Diagnostic trouble codes (DTC's) from the heater control panel. To run the diagnostic function, do the following:
1. Turn the ignition switch ON (II).
2. Turn the fan switch OFF.
3. Press the recirc control button to select Recirc (recirc light on.)
4. Press and hold the recirc button to select Fresh (recirc light off) and continue to hold the button down until the recirc light comes on for two seconds and then goes off.
5. If the system is okay, the recirc light stays off.
6. If there is a problem, the recirc light blinks the DTC to indicate the trouble. One blink=a problem in the air mix control motor circuit. Two blinks=problem in the mode control motor circuit
Three blinks=problem in evaporator temp sensor circuit.
7. Turn the ignition switch off to cancel the self diagnosis function. Run the diagnostic again after repairs are complete.

Note: the air mix control motor has a rod which connects to a plastic link. The link controls the mix doors and also connects to the heater control water valve via a cable. The air mix motor may check okay, but if the link is broken then you will still have problems. the motor is on the bottom of the heater unit in the front passenger's foot well.
