2014 Bobcat S570 Air Conditioner is 2 blink and not working. I put a new switch in it and that is not the problem still is blinking twice. The low side pressure is 80 psi and the high side is 80 psi and the compressor is not running. I bought the machine used and the guy said it needed recharged but it is at 80 psi. What is the next step? Jumper the compressor or?? I have never heard the compressor run yet but only owned it for a week or so. Two blinks on the A/C box means electrical problem but I have a sick feeling it is a compressor. What to do next? Any help is appreciated. thanks.

It is always almost the same pressure when the machine is not running. On the Side where the Cab Harness comes down, there is an extra cable with two wires and a connector. Unplug this connector and put a paperclip in it. Does your compressor starts working? Is the Thermostat still blinking? That bypasses the pressure switch, which would mean that there is not enough freon in the system.
After that you can test the compressor for resistance, should be below 5 ohm. Check also your fuses and your switch inside the cab.
Thanks for the tips. I pull the connector and jumper the pressure switch - the compressor turned on and the T-stat red LED went solid. I added one 12 oz can of R134a and the AC system got cold and ran solid at about 22psi. I am happy the system is working BUT I let it sit for 2 hours and now the T-stat is back to blinking twice and not getting cold. I have a can of the leak seal with refrigerant to put in but I am thinking that won't fix it long term. Any suggestion regarding the leak seal -good idea or bad. I am thinking about getting a sniffer and finding leak or any other suggestions. Thank you for all your good advice much appreciated..

My opinion: I am not a friend of any Seal stuff, does not matter if Engine, Coolant, Hydraulic or Freon. The only sealant I will use is in my lawn mower tires, because of all these Stickers.
If you have access to Nitrogen, you could evacuate all the freon and charge the system with 350 PSI of Nitrogen. Use a Soap spray bottle and you will find your leak, you might not even need the soap bottle depending on the leak.
