2012 ac only works at 61 or below

Good morning guys I was hoping to get some help with the AC on our 2012. It seems as though it will only blow cold if you set the temp to 61 or 60. At 62 its like the AC isn't even on. It's lukewarm at 62 but freezing at 61. Any ideas on how to troubleshoot this? Thanks for any help.

Does the heater act the same way (i.e. cant maintain a constant temp?) Easiest to try is to ensure the vent where the temp sensor is located (small grate or microphone looking thing on the dash) is clear of detritus. Try some dry compressed air (or can of compressed air used to blow out computers) and get rid of the cobwebs.

Next would be the mixer doors and motors. Good news, is it works. Bad, is you have to troubleshoot the mixing doors (if you are small and wiry, not too bad a job)
