how many expansion valves are there in the Honda Odyssey?
What is your question?
The A/C in 1999 honda is blowing warm air despite 1- no leaks, 2-vacuum and replace new coolant (freon)
the air in the back is slightly cooler than the front, the a/c lines from the motor that goes thru the fire wall are not getting cold, all fans are working, all else are working.
Where are the expansion(s) valve(s) located an d what are the part numbers.

Hello, your vehicle would have an expansion valve by the front evaporator core and one by the rear one. Whether or not you need one is subject to proper diagnostic testing. It's a difficult job to replace one, as you need to access the evaporator boxes. However, if you have debris within your system, for example, or a leak, it would be necessary to repair.
From my parts film, without a VIN specifically:
Front: 80220-STX-A01
Rear: 80221-S0X-A51
Additionally - 'IF' the expansion valve is restricted or otherwise malfunctioning - the A/C *manifold gauge set* would indicate so via pressure readings..
