S600 AC problem
So at the start of each day my AC takes as much as 15 or so minutes to actually get cold. It blows warm as if the compressor is not turned on. I switch it on and off many times and after a while it finally works. Dont know if me switching it on and off even helps. When it does finally work, it blows ice cold on all vents. Anyone have this issue or any tips?

Hello Sir, did you finally figure out why AC blows warm for 15 minutes?... My S600 does the same thing

No gas no cooling.... ever. Certainly worth verifying that there is sufficient refrigerant in the system.
If it has enough 134A in it you will get to replace the compressor.
It comes out the top after pulling the radiator and rad fan. If everything is original this is your opportunity to give it a new SERP belt, all the belt idlers and tensioner. How old is the water pump? Easy replacement now. If the radiator has never been replaced.... look real closely at the plastic seam that intake air passes through while finding its way to the air filters. Radiator likes to crack there for a leak that makes coolant injection to the intake air. How many miles? The alternator will live 100-120K miles. It also comes out the top.
With enough practice I got to be able to get the radiator and fan out pretty quickly. Due to doing aforementioned replacements mostly one at a time... all within 15,000 miles. Hindsight being all that is.

Pop your hood and with the AC on max put your hand on the larger diameter refrigerant hose which is usually somewhere in the upper right quadrant of the engine bay up high and about 3/4 of an inch in diameter it should be ice cold and sweating if not then you probably are low on refrigerant. I have a thread going with a slightly similar problem mine blows hot on Startup after the car has been sitting but then ice cold I believe mine is a blend air problem.
