Does anyone know if it is required to remove the negative battery cable before replacing the Cabin Air Filter. I have read the thread on how to do it and there is no mention of it there. It's hard to find anything in the Service Manual about the CAF, although there is mention that before you tackle anything in the instrument panel you should disconnect the negative cable. I just got the charcoal filter from Advanced Auto and there is a generic warning about disconnecting the negative cable. Anyone know for sure. Don't want to disconnect if I don't have to. Not sure what all has to be reset after disconnect.
