Got a new to us 7060. Previous owner said the air works but have
to add free on once in awhile. It was updated to the 134a at
sometime. Anyways I added 3 lbs of free on. The clutch on the
compressor runs and works. The low pressure line got cold and
frosted up. But no cold air in the cab. The high pressure line
doesn't get hot at all. Its like it's not circulating. I tried to
look in the window on the reviever dryer for circulation but can't
see through the glass. I then shut tractor off and later started
it and now the line doesn't get cold anymore. Could a sensor be
bad or a plugged dryer? Any help would be appreciated. Thank you
