I searched for this problem in old threads with no answer
my blower motor has a 3 minute delay at times
other times it goes right on
doesn't mater if in heat or cooling stage
High fan or automatic mode
There is voltage to the fuse and leaving the fuse when fan is not working
car is 88 560sl
Any help would be appreciated
