Hi all,
Having an intermittent problem with the air conditioning in my 2012 Acura TL.
Can work fine for days then suddenly will stop cooling. The air starts to get warmer through the vents. Still blowing strong. Sometimes turning off the air conditioner and then turning it back on results in return of cooling. When this happened the last time, I turned the automatic temperature control up to 70 from 66 where it was and cooling started working again.
About two weeks ago the compressor clutch relay was replaced at the dealer and for two weeks there were no problems. Dissection of the old relay showed pitted and burned contacts. The dealer had run diagnostics and no electronic faults were found. Refrigerant pressures/levels were OK
So, what are your thoughts?
1. Defective relay? seems unlikely. Used and original part.
2. Internal temperature sensor malfunction
3. Outside ambient temperature sensor malfunction
4. Something more expensive.
