This is getting confusing
The pressures are normally taken at 1,500 rpm not 2,000. You low #s are way too high if compressor is staying on and high # is a bit low. Out put temp of 35F at speed is too low! That's too close to icing up your evaperator.
You said that the pressures were normal with water on the condenser but didn't post the pressures. Are you convinced that your pressure and temp measuring is accurate?
If the water test made it work properly than it really suggests a problem with the fan for condenser.
A low reading of 90 !! You shouldn't have any cooling at all!
Maybe it's just me - but this doesn't make sense??
