We bought our 2013 XLT explorer certified pre owned last May, the AC has never really run that cold. In the last few weeks it's been horrible. Hubby replaced the cabin air filter, did not fix. Recharged the other day, still not fixed. Mechanic friend mentioned possibly a bad sensor?? The compressor clicks on and off frequently, like several times a minute. So what sensor am I looking for? Or thoughts about what else this might be? Thanks so much!

 

A certified pre-owned 2013 should still be under bumper to bumper warranty. Why not have the dealership take a look at it, starting with checking the charge level of the R-134a refrigerant? If the level of the charge is low on this new of a vehicle it would certainly suggest there is a leak somewhere.
