Life Support

The AC was cycling off and on last night on The Beast.

Plenty cold, but at the desired temperature, it was alternating warm and cold.  Full cold would stay cold.

With the over computerized climate control system, that's a symptom of being a little low on Freon R134a.

So I hooked up my gauges and put my thermometer in the vent.

Running about 50psi low on the high side, 25psi low on the low side and 8 degrees warm at the vent.

So I added a little R134a and now the pressures and temperature are perfect!

I wonder how much this would have cost to take to a shop.

    Too much at a shop, that's why I bought a set of Harbor Freight gauges to diagnose the failing air in the Buick. $65 for gauges, a can of R134 and some research versus $100 to say your compressor is dead.
