AC needs constant reset
91 coupe, electronic control system. Had the unit (134 conversion) vacumed and charged, A/C cold then car hesitates and misses, A/C light on auto setting begins to blink and blows hot. I can pull fuses from Courtesy and Radio to reset and systems blows cold again for a few moments until hesitation and starts all over? Any else experience this, not sure where to start?? Thanks in advance to all, what a great tool this forum is, thank you.

Just in case you're not getting it's memory cleared out, disconnect and reconnect the battery. Then if it starts flashing at you again, don't clear memory until you go here: https://www.corvetteforum.com/techti...=193&TopicID=2
Then, when you know what the code is, post it - And if you want to, you can note and post all the binary data that it spits out. Also, if you have a scanner, get the Pressure Sensor signal with it off, then when the clutch engages and finally, what it reads when it cuts off and sets the Code.
