I'm trying to fix my fan switch. how do I break down the dash

Remove the electric mirror adjust switch from below the dash (if it is there) - 2 screws - let it hang by the wires. This hides two more screws for the climate control cluster. This drops down and pulls out, but only a few inches. You don't have much room to work because the wires and cables are tight. There are two fan switches, the one at the top and another one to the side that also controls A/C. The vacuum selector is on the lower back.
