Why would a 1998 grand marquis's air conditioner blow cold air for a couple of minutes then blow hot air?
Could be low on refridgerant or have a faulty pressure switch. The pump has to be running for the air to blow cold. If the refridgerant is low the pump will click on and off and not run long. If the pressure switch is bad it will not sense the refridgerant and do a similar thing. If you don't have access to pressure gauges I would go to the auto parts store and ask them if they can put a can of refridgerant in or buy a kit to do it yourself. If that doesn't fix it you may have to see the mechanic.
