I'm not sure if the Compressor is kicking in but I guess since a little cold air is coming out of the vents then probably it is. Plus you hear something when you press auto a click sound.
Now since I had the system cleaned and vacuumed due to the heater replacement, i don't know what type of Gas they used on it. I've read somewhere that the 164 is not supposed to use FREON 12. Since I don't have the manual and Car Disk has the american version, any of you guys knows what type of Gas it uses. Is it by anychance R13a or rather the new type of gasses like modern cars? I'm going to have it checked out by an A/C Specialist but he need to check the type as FREON 12 is no longer Available!
Any ideas on what the Super's Gas is? Any Idea how after a thourough A/C Service the A/C never got to cool as much ?
Your help is much appreciated.
Regards !
You need R134a, and PAG 46 oil in the system.
Sounds like the system is not charged enough therefore not cooling. But the main reason that these cars have bad A/C systems is the condenser and work done on it. I use a parallel flow unit that I made up for these cars. I get well below 12.7˚C from the vents, sometimes lower.
You need to change the A/C filter, expansion valve. You may have a clogged filter if never changed or a stuck expansion valve if not cooling properly.
Make sure those items are replaced, system is evacuated for at least 1 hour, proper oil and amount in the system and compressor. Sanden compressor/system takes 177.44 cc of oil (PAG 46, synthetic).
Change o-rings if needed. Recharge system and you should have a very cold system.
