For the past couple of weeks I've noticed that my 1980 Mercedes Benz A/C has been having some problems. It appears that sometimes the air con will blows cold air and at times air coming from the A/C vent giving nothing but just blower.
I had the car subjected for leak testing but no leak was found. Additionally, compressor was also tested and found to be in good working condition. I also had freon (R-14A) charged couple of months ago.
Typically the problem happens whenever I drove past 100 km/hr and seems that the A/C losses it coolness. It also appears that whenever I set the A/C controller to Max, after quite sometime the cold air coming from the vent seems to disappear. In order to restore coldness, I need to shutoff the A/C for several minutes and re-started it again.
Also, I noticed that during high noon (location - Asia Pacific), my A/C can't seem to give enough coolness unlike if I'm starting it early morning or at night.
Any thoughts on the issue I'm having?
Thanks in advance.
