Hi All!
I have a 1995 Odyssey that has always had ice cold a/c. The other day it started blowing warm. When I put the gages on it at 80 degrees ambient temperature, the low pressure side was reading 45 psi and the high pressure side was reading 250 psi. Temperature out of the vents was 58 degrees. I'm thinking that there is some blockage or debris in the system partially blocking the expansion valve. I picked up a new expansion valve, took out the lower glove box, but only see the evaporator box. I was hoping that the expansion valve was external to the evaporator box, but it looks like it may be internal. Can anyone tell me the exact location of this expansion valve and the best way to access it? Thanks in advance!!!

Looking at the service manual you will need to get the top cover off the evaporat to get to the expansion valve.
I am going to have to say that you wont get the cover off without pulling the evaporator out of the car.
