So a few days ago I noticed something weird with the AC in my car. It would take 20 mins. to fully cool down the inside of the car. Than yesterday same thing so I decided to adjust the temp. from 65 to 75 and for 3 mins. the temp. did not change even when I turned off the ac and upped the temp. to 80 the temp. still was just warm. Does this sound like a bad temperature switch or something else? AC is full of Freon so rule that out. The temp. seems stuck at around 70 degrees. Thanks, Dave

 

What's your mileage and is it a CPO?

 

Mileage is 34,000. What is a CPO?

 

Certified Pre-Owned = CPO

 

Yes it is a CPO that I bought in 2012 with 15,000 miles.

 

Your AC system only produces cold air at one temperature. When you change the temperature in the vehicle what you are doing is adding heated air to the cold air for your desired temperature. If you feel like the temperature is the same no matter what then it probably is a bad thermostat in the vehicle or the flap that is supposed to open and close from heated air is getting stuck to not change the temperature.
