A/C not working properly

Hey guys I’m currently running into an issue with my A/C,and it’s really bothering me with this Texas weather.so my problem is that the A/c stay nice and cool in the morning and once i get off work it goes crazy blowing hot air and cold air,aswell when I come to idle it gets hot,and when I start going it starts blowing a lil cool.its odd and bothering me so much.
so far I have replaced
FANS
A/C switch
sunload sensor
ambient temp sensor
and I have done a recover,vac,and recharge twice

Rule #1: don't throw parts at a problem without knowing what the problem actually is.

More often than not when the AC stops blowing cold when the car stops is due to a lack of air flow over the condenser- usually because the fans are not doing their job. You replaced the fans, but did you check to see if they were running?

Read this post as it will tell you how to run the IPDM/er test. During this test, both fans should run at 50% (medium) duty for 5sec. and then 100% (full) duty for 5sec. At full speed they should both be roaring loud and moving a ton of air.

Run the test, report back, and we'll go from there.
