Just split my 1086 and put a new clutch along with IPTO gear and seals etc and when I spit it I removed the trim on the pillar to allow the ac lines to move with the front of the tractor but now that I got it back together I have no ac, worked perfectly before. tractor has a new compressor and is converted to 134A, I can hear the compressor kick on with engine off key on and blower motor on and turning the AC knob tried to see if it was low on Freon with a auto parts store gauge and it says zero and will bump up just a little bit when squeezing the trigger but it won’t take anything, no red light on in cab, only other thing I did was put a new headliner in it and had the AC control and what not connections removed, dammit! the AC worked perfect before, probably my favorite thing about the tractor, any ideas where to look first?
