the heater bypass is quite simple, if you look at the firewall you will see two medium sized coolant lines, remove them from the firewall and link them together using a proper sized tube, you can purchase a kit at a parts store quite cheaply

Should be fairly easy. Make sure to disconnect the positive battery cable. Remove the cover from around the column behind the steering wheel. Should take a star driver to remove the screws holding the cover together. Once the screws are removed pop the cover apart and you will see the multifunction switch on the column, should have two to three screws holding it to the column remove the screws and it should come out pretty easy replace with new one and put back together.
