I have a '95 Grand Marquis with an A/C problem: it usually starts off blowing cold but after a while it will suddenly blow hot, then switch back to blowing cold again. There does not seem to be any pattern, sometimes it will switch between hot & cold back after 30 seconds, sometimes after 10 minutes. I only have one A/C repair place near me, and not being a DIY I am hoping for guidance so won't get ripped.
It sounds like the system is low on referigerant. That system will hold about 3 to 5 pounds. Adding a pound or two will fix the concern. However the sytem has a leak somewhere. That is where you will spend the bucks in locating the leak.
