Customer Question

85 Pontiac Fiero 6 cyl 2.8. A/C; Compressor is new, new oil, new accumulator, new hoses. I fill the low side with R134a. I run the compressor to circulate the R134a. The compressor keeps cycling on and off; a few moments on, a few moments off. The R134a does not appear to circulate. If I continue filling the low side with R134a, the filler gauge goes into the red. What's going on?

Do you have a set of a/c gauges that will read the high as well as the low side?
