Theres several places freon can leak. Either the evap has a hole in it, the oring seal at the connection is bad or a hose is bad. With that much oil blown oil id say probably a hose. Kind of strange the front is blowing cold but the sleeper isnt as that they are supplied by the same compressor. Unless your saying the apu air isnt blowing cold.

The evap should be right next to the blower. U can look at where the refrigerant lines go into the cab as a reference. Are we talking about the apu a/c is leaking or the main engine on sleeper ac is leaking?

i seen it the evap i haven't been able to see if it the sleeper or the engine but the cab is still blowing kind cool and the sleeper is warm but i think they are all tied in

[smorgan87]

If engine is running and front ac is cold but rear ac is not id check the blend door for the rear ac. Id also hook up some gauges and check the pressure on both then main ac and apu ac.
