Just a note to anyone having a/c problems with their L322, don't go the same route I did, and think blowing hot on one side is a blend motor issue,
having stripped out the whole dash and finding no problems :doh:.I did manage to download the rave manual, and after some serious searching found the fault was cause by a fooked duel heater control valve, which lives on the n/s/f inner wing just below the abs unit.It had developed an inturnal leak and burnt the coils out thus not allowing the valve to close and sending hot coolant to the heater matrix,this in turn can also burn out the control panel,not on mine tho, 47dgs outside and all cold inside!!
