300se heater problems

My 89 300se has just had the regulator replaced a couple of months ago and man, the ac blows now. Today I noticed it might be getting a little cool in the mornings the next few days and I checked the heat. Now, the air blows through the vents good, but the air is cool and not hot. Can this be the monovalve or the temperature sensor or maybe something else? Can anyone help?
Last winter I had the brushes replaced in the blower motor and the MB mechanic stated that the armature was in good shape.
