Oh and Wedley,
something I just noticed this weekend,the lousy heater valve on the accord doesn't close all the way (yeah I know some are designed to stay slightly open), but first turn your knob all the way to max cold and then manually close that water heater valve (located just underneath the intake plenum on the 5th Gen accords). You'll notice it moves just a notch more in the direction towards the front bumper, that's the complete closed position. Try not to turn your heater knob until winter hits and you need heat. Apparenlty for me, I tried adjust the valve, but the way it is designed it just won't allow to close completely, unless you manually shut it all the way. Dude I tell you, big difference, the damn a/c almost froze me out over the weekend, quite impressed indeed, especially for the R-134 system and in a black car.
hmmm, not sure if i can do that becuz my hands are always cold when i drive. but ill try to resist the cold, but i usually do not need to turn the knob all the way, at 2/3 its blastin hot air. but thx for the advise.
