149k miles, Had issues with power steering leak. Was on highway and the pulley broke off and sheared the a/c line. Power steering problem has since been fixed. After fixing power steering problem, (Leak @ rack, and Pump and pulley replacement) i tried to use the defroster on a cold morning, Service A/C light came on in information center. I turned the defroster off an a few minutes later, ac light went off.... Do you think replacing the hose that was destroyed (but not leaking) could be a remedy? New belt was installed with pump and pulley. all was working fine until pulley broke.

Re: Service A/c Light 4.9 '93 Sedan...
It could even go a little deeper than that. If any debris got into the system when the pulley broke or from driving around, it could cause the compressor to fail as well. I believe the system can be flushed, which is probably what I would do if a hose broke. You'd probably need to replace the orifice tube and accumulator as well with it being open to the atmosphere.
