Question about 2004 Honda Odyssey
Just had my a/c serviced and recharged and it quit again. The air flow would not change from to top to bottom to defrost, etc., when I pressed the mode button ( automatic air conditioning system). The temperature of the air didn't even get very hot when I turned the dial clear over to hot. WHAT IS GOING ON??
There is a switch that controls the air to move from def. to vent to floor find out if it is an elec. contrl or vacuum controled vacuum lines are comon for breaking if this is the case replace vacuum line this should fix the control problem also check all fuses and relays for problems

It sounds like a vacuum leak or blend door problem.

I read about this issue while I was looking for a fix to mine. Try the following:
Remove fuse #13 for 30 seconds or more from the passenger side fusebox. This will reset the door and the clock.
1.) Disable the power door switch on the left dashboard.
2.) Remove the power door fuses located under the front passenger leg area.
3.) Manually open and close both sliding doors.
4.) Restore the power door fuses located under the front passenger leg area.
5.) Enable the power door switch on the left dashboard.
6.) Try opening the sliding doors.

you have to replace the resistor under the passenger side dash. the wires coming from the blower motor runs to it. if it is back the module wont let the a/c work. common problem. easy fix

Sorry for the delayed response. For future reference, the blower motor resistor in an 04' Honda Accord is located under the glove box and a little to the left if you are facing it (the glove box). You just need to pull out the plastic panel (yes, you can just pull it out by hand, no tools needed for that). It should be right on the fire wall with a plug going into it. If you reach in there and pull the plug (it has a little notch so it clips into the resistor more securely; make sure you push the clip in) it should have 4 flat prongs on it that go into the resistor. The resistor itself will have 2 phillips head screws that are holding it into the fire wall. Unscrew them and you have the resistor. If you can unscrew both screws before unplugging, it will be easier to see how it unplugs. I know this sounds complicated but once you get in there you will notice it's fairly easy to change out.

Lets get started. Place the key in the ignition and turn as if to start your minivan - but do not actually start your Odyssey.

Welcome to FIxYa.com
First check the heater control valve install a piece of 10mm hose to top so cable will not come off ( see diagram)
Check coolant level, do you have heat at defrost?, if not --replace heater core and flush coolant.
