Hmmm, I noticed this just today in our 2003 EX. Cabin air filter is fine. The front AC does not seem as cold as the rear AC. Outside temp is a moderate 85F, with 30% humidity. Do you notice this disparity most at idle with the A/C on? Does your condenser fan (passenger side) spin at high speed?It just started to notice that my 2004 Honda Odyssey's front ac is not as cool anymore (wife is driving it most of the time) but the rear ac is working. I have this van for the last 7 years and has been working fine (ac) all along. I believe all the switches are working, as when full auto is on, the light will go on and will come off if the desired temperature is reached when rear ac is working. Has anybody have similar issues before?
This statement makes me think you may be low on refrigerant or your compressor is going out(hopefully not). When driving, the compressor will run at a higher speed and create more pressure. In a normally operating system you should not notice the air get colder when driving vs idle.It only gets very cold when we are on the road.
