Last year, I rebrushed the blower motor and added a 80amp bypass which seemed to do the trick ('82 300sd) in getting my A/C to function again. My blower does not work now though will when I power it directly. 80 amp fuse seems fine along with wiring - can anyone offer any ideas why I no longer have fan/blower function. CCU was fine too at the time . . . . any thoughts? Thanks! Getting warm again this weekend!
