Default issue with heating on the A/C panel

Lately I have been noticing that I have to crank it up to 85 to notice good heat. If i drop it down to 83 the left center vent feel cool and the right has heat.

Is this a problem with the A/C control?

start with the easiest. check your engine coolant (after the car as cooled down) dependin on your coolant level, if its low you will only blow warm air..

if your saying you do have heat out of one vent and not the other, might sound dumb but double check the selector on the vent that allows the air to come through. it may be closed all the way not allowing air to come through on that vent.

It has cold cold A/C at 65. as you go up in temp the left vent stays cool until 85. lol no both vents are open and the selector is set to blow out of the top face vents.

Coolant level is find since I checked it Sunday.
