There is on my 95 940 a high pressure a/c hose from the compressor to the condenser. Under the RF bumper, the hose terminates in an aluminum tube before connecting with the condenser. This tube is secured to the underbody with a vinyl-coated steel clip, which in my case rusted and wore through the aluminum tube causing a loss of R134. The hose assembly is expensive ($200), so check the bracket and make sure it is not destroying your a/c hose/tube through corrosion.
