Pull the panel down slightly and then back towards you. It should pull out of the rear slots that hold it up. The sampler motor attached to the panel and there is a rubber hose that runs from the sampler to the display on top of the windshield. disconnect this hose. (It is a pain to get back on, but you can with patience.) You can either pull the sampler out of its clips or pull off the wires going to it. I have done it both ways and it is a little easier to reattach the hose with the sampler free of the panel. The sampler just pushes into the clips holding it in place.

When you are putting the new fan in place put the long phillips head screw you took out of the fan cover through the front screw hole and temporarily screw it into the air plenum. This will hold the fan in place while you screw in the fan attaching screws. Then back this screw out and install the fan cover. Make sure that the cover seals and that the fan wires are going out through the provided slot.

Before you tighten everything up, turn the key to the second position and make sure that both the blower and sampler fans work. Put the blower on high, auto and low to make sure it spins at all speeds.

When you install the panel, first slide it in and line up the air passage in the panel with the air duct coming from the center console. Then stick the panel into the slots at the rear (firewall side) hook up that darned sampler hose then carefully line up the three screws in the front. You will probably needd a small flat bladed screwdriver to manipulate the metal clips the screws go into.

This should all take you under an hour.

Good luck!
