Air conditioner

Asked by Aug 04, 2019 at 02:20 AM about the 1997 Mercury Grand Marquis

Question type: Maintenance & Repair

97 grand marquis ac worked great.
Had intake manifold changed and
plugs, wires, coil packs, air filter,
and fuel filter changed and it
started blowing hot air immediately
following repair. Took it to auto
parts store to check refrigerant and
they said to change orifice tube.
But now refrigerant barely goes in
slowly and cooled for a minute but
never was able to fill to proper level
only 1 can in and the 1/2 can of the
oil went in at this point.
Compressor comes on breifly then
cuts off and will kick on briefly way
later.  Any advice would be
appreciated thanks in advance

Most likely the refrigeration system was open when the other repairs were done. The shop should have pulled the system into a vacuum and recharged it for you as part of the other repairs. If the air conditioning was working before the other repairs were completed I'd take it back and let them fix the air conditioning for free. Hope that helps! Jim
