So I have been making trips back home here and there and was back there this weekend and got this out when it was high humidity and about 90 degrees out. I figured I should give the A/c a try. Was able to record 58 degrees coming out of the outlets! pretty damn happy about that!! With only me in the car it kept it manageable, but I dont know if I would be comfortable with another person in there with me in a suit for a wedding, but I will take it!

I think over the winter I am going to get the drive shaft looked at. I didnt like how the U joints felt once I installed them so I am going to make sure it isnt bent because that car is not as smooth when compared to the Caribbean is at certain speeds.

On the driveshaft and smoothness you might also see if anything in bulletin 56T-10 and the corrected version -10C applies to your Patrician.

Per the manual, ideally the temperature at the outlets should be high 30's steady state after a bit of driving. The service manual gives instructions for adjusting this on page 5.

Or do you have aftermarket A/C? I forget.

Does it by chance have R-134a refrigerant? If so, it's known to be much warmer when used in an old system not designed for it. That said, Classic Auto Air can apparently rebuild the components with R-134a in mind.

The system is a modified version of the Packard system. I am running newer valves, parallel flow condenser, and a Sanden compressor. Running the original Evaporator and box. I am running R134a

and howard, Ill give that bulletin a look see

In that case, I would say that your expansion valve and other components need to be modified for it too but warmer (or rather, not so cold) air is to be expected with that setup. Also, with an unmodified system, you shouldn’t fill it with the refrigerant. I don’t recall the details nut I understand that you need to use a little less.
