Group, My 1987 560sl dose not blow any air out of the center dash vents. All works ok as far as cooling and heating goes but air is discharged from the right & left dash vents, the doors, under the dash, but not the center vents. There is a full flow of air coming out of the defrost vents onto the windshield & that fogs up the glass outside of the car. I suspect that some door or flap is stuck in the defrost mode.. Has any one had this happen or dose any one know what to do for this type of illness? I am going under dash diving next weekend and could use some tips. Any help would be greatly appreciated.
