Figuring the system just needed a recharging I went up to the auto store and bought some R-134a (which has the oil in it). This was about a month ago on one of those nice rare warm days we got here in Michigan. I followed the directions of having the car on, with the system set on High AC and the reading was low. It seemed hard to fill the unit but after a bit I got in the correct amount. Still only warm air blew. I shut off and restarted the car. Still nothing.
I then noticed the compressor was not kicking on. So I put more R-134a intot he system and then the compressor kicked on, but would go down drastically and then cut off again. At this point the reading was at the "Yellow" part of the gauge.
So I left it for 1-2 months and now it is warm out in the 80's. I decided to take another look today. I put the bottle with the gauge on the system (Low side) and it still said the stuff I had put in there before was in there. So I decided to let all the stuff I ahd put in there out and start over. I followed the directions ont he bottle of the R134a to the letter. This time the stuff flowed in fast and easy. I got it up in the blue and went to check the air, and it is still warm. And the Compressor is still not coming on, unless I overfill the unit but then the pressure drops kicking the unit off and once it raises again the compressor comes back on. At this point I have no clue.
Do I need to vacuum the system out? I also unplugged and replugged in the connection at the top of the compressor unit and it seems connected and still nothing.
Thank you for your help
