h block removed on evap.side.High side still holding pressure

Postby my2monkeys » Mon Aug 28, 2017 7:48 pm

89 Jeep Cherokee 4.0

Compressor was 0 psi on low and 100 psi on high at idle. A little freeze on the h block.
Im thinking stuck expansion valve. So I remove lines at evap. to h block with low and high still hooked up.
Only a little pressure coming out onthe high side of block.
Is that a sign of stuck valve?
