I have a 2015 corolla LE that I bought new in December 2014 with a production date of October 2014 in Canada. Now that we are out of the deep freeze in the Northeast, I have noticed more and more that when I turn on the car on warm days and the a/c switch is on, the air from the vents does not start getting cold for about 1-3 minutes. It will blow the stale air during this time frame. Has anyone else experience this "delay" in the a/c starting to get cold once the car is turned on in warm weather? When the a/c button was on all the other cars I have ever owned, I almost immediately started feeling the air become colder. Strangely enough, if the a/c is on for a while after the car warms up and I turn the a/c off, wait a few minutes, then push the a/c button again, the air from the vents starts getting colder immediately. It seems to be a "cold start" symptom.
