My Benz S500 Ac Doesn't Cool Everywhere by justiniyke29: 10:48am On Dec 02, 2018
I just got a Benz s500 w220 and I noticed that the ac only cools from the center console vent of the dashboard, all other vents blow hot air(as in like steam engine). I Ave drained and refilled the gas but it still remains the same.

Take it to a garage for proper diagnosis. A lot of things could be responsible

I took it to one ac technician and he says I should change the air cleaner first but I don't know why one vent will be chilling and the others are blowing hot air. Thanks for the advice

Your refrigerant has dropped.

You have leakage in the system it could be your compressor seal or evaporator.

Your cabin filter isn't the cause for that.

Visit a proper AC technician, it could be a whole host of issues....

Might even require a complete AC system overhaul...

when you say system overhaul what do you mean? Is it refilling again or changing parts?

[quote author=mosbus post=73484609][/quote] so should I first check out for leakage or what? Thanks for the advice.

If you are in Lagos, visit AutoDoc. His garage is at Ifako-gbagada. He would gladly attend to you on this swiftly.

He won't have time for this. The op should be ready to wait a long time to have service. I recommend radautoworks seems the man there has a thing for Mercedes Benz air-conditioning system.

With the help of a manifold guage what was the pressure on the high side and low side

General rule of thumb if you are buying an older Mercedes Benz, expect all sort of associated gremlins... The previous owner probably sold it because he does not like gremlins (I bet he said AC only required regassing)...... One of the oldest lies in the car trade.....

Expect to see more gremlins, of an electrical nature etc etc etc

Fixing the car for basic functions is cheaper than owning a Japanese of similar specs

They rode in a car already abandoned by the hotel. Benz threatened to sue the royal family when such claims were made.... The royal family promptly kept quayet and never mentioned such heresy anymore

check high and low pressures with a pressure gauge.

if withing normal limits check the duo valves that transfer heat from the engine to the cabin. They are designed to feed the cabin warmth by regulating the quantity of hot coolant flow to the heater core. When stuck open the a/c will feel in efficient.

He doesn't operate at your level of thinking/generalisation. You also could go check him out.

I am not sure but I think I saw 120 and 50 something when they were checking it while filling up.
