Early 944 AC troubleshooting guide
 

Can anyone point me to a troubleshooting guide for the air conditioner for an early car (1984 944)? I would like something that provides step-by-step procedures for help in isolating the problem. Many thanks.

BTW, I got my Early American plates for the car on Saturday. Early American plates are for cars over 25 years old in Connecticut. By pure happenstance, I got a great number. http://forums.pelicanparts.com/uploa...1371466985.jpg

A nice coincidence on the plate.

Since you are a member of Pelican, class 2001, you probably know about Clarks-Garage HVAC-02, AC troubleshooting and repair. Probably the best for early cars.

The WSM also has a couple pages of DIY tips.

Basically, after a visual inspection, you need a set of AC guages to go further.

If the freon is low when you start you need to locate the leak with a dye or electronic leak detector.

To recharge you need a vacuum pump 2.5 cfm and up to evacuate and do a leak test.

SO, do you have R12 or R134a in the car? Guages? Vac Pump? Leak detector or dye?

Thanks John. I overlooked that link from the main "Garage Shop Manual" page. I was looking down further in the Troubleshooting section.
