I am having ac problems. The ac on my 78 dodge motor home 440 cid has had several problems in the past. compressor has been replaced along with several other components. Just recently replaced a suction in line filter and yet pressures still will not come in to right alightment. Suction line pressure after only two cans freon sits at 35. High side 250. very hard to fill system to right amount. With all this the suction side on the head is 10 psi. should the two low sides not be close to the same. My only thought at this time might be to factory filter if that is what it is in the hose, or maybe the valve (can't think of the name) in the suction side of the compressor itself. Any help will be appreciated. Also new new filter drier and expansion valve a couple of years ago. Thanks. Larry in Texas
