How do you get at the A-coil to clean? The fan blows good, but not much air comes out of heater, defrost, or vents. I think the A-coil is blocking the fiow, but I don't know how to get to it to clean.
Thanks in advance!

First discharge the a/c system then disconnect the accumulator and the evap core under the hood, locate the bolts that go thru the firewall then split the case! This is a lot of work to try and clean an evap core, first check for a cabin air filter! remove the cowl under the wipers and check for a filter...
