okay, well ill start with specs
1996 grand cherokee limited 5.2 ( rebuild engine ) ive put about 10,000 miles on it so far, everythings great
my a/c has NEVER blown cold for more than 2 weeks in my jeep for the past 3 years , so i figured id finally tackle this feat.
so i ordered the liquid line ( which has the orifice tube in it, only way to change it,)
i also ordered the accumulator, and both high and low pressure switches.
now when i put the new accumulator in, i added 4 oz oil directly into the accumulator, i then took the compressor off and spun the clutch and pushed out all the oil, i then added about 1 oz of oil to the compressor itself. now i did a deep vaccuum for 20 mins, no leaks at all, checked out great.
then i charged 28oz of freon to the system, just like the decal said.
my problem is the a/c will NOT cycle off. it just stays on constantly, im getting very cold temps inside which is great, but i know the compressor is supposed to cycle off and on.
my HIGH side pressure is at 350 !!! and the lowide is right under 50.
the high side pressure is too high, the temperature outside today was 60 degrees.
my only thought is that theres too much oil in the system from the 3 years, of added dye here and there. could this cause my symptoms ?
i recovered the freon, and started over adding only 10 oz. and the clutch would cycle on and off normally while charging, does this also suggest over charging due to too much oil ? im kind of stuck ,
my only other option is to take the system apart again and flush out each individual component, which im not against, just not sure why this is happening, any thoughts would be great, thanks for reading guys
