Done this before. 1st disconnect your battery. Then remove the air bag. Unfortunatly there is a special tool for this (see pic), but if your handy you can use 2 allen wrenches to "pop" the two left air bag release springs to loosen the left side of the bag, then do the same for the right. Once the bag is out of the way, remove the wheel bolt (see pic). NOTE: this wheel does NOT have a master spline. You can put this wheel back on crooked, so MARK YOUR SPLINES with a sharpie before pulling the wheel. At this point, my wheel pulled right off without the aid of a wheel puller.
Once the wheel is off you will have access to the screws that hold the switches and trim covers on.
