So i encounter this problem twice. Both after a regular carwash nothing done inside the hood. I always turn on my AC using Auto and leaving it as is for regular use. But when i turn it on all indicator is on and if i manually set it the air coming out is hot as a heater. Only temp that will blow cold air is 19 and below.
After few hours on both incident it'll automagically fixed again and works normally. As usual when i turn the AC on Auto the indicators is normal as it usually should.
So what happened on the 1st pic? I don't know what it caused as i have little knowledge about this and how can i prevent it to happen again
