Does the temp get lower at all? If not, time to replace your heater tap (on the firewall under the bonnet, right behind the engine). It's probably been leaking, corroded and is not turning off the flow of coolant. There are other possible problems there, too but that's the most common I've found and a good place to start. With the engine and cooling system cold, reach back and grab the arm of the tap and see if it moves. If it won't move, it's seized. I got one of mine loose and it worked for about a year before it stopped again. It's a cheap part to replace. It's also possible the tap is not getting vacuum. Check the two vacuum lines coming from the right wing to make sure they're both connected and not leaking. One should come from the vacuum reservoir on the left wing and one goes to the heater tap. I can't recall off hand which is which.
Hooking the A/C back up is a gamble. There's probably a reason the belt is off and that reason is most likely that the system has degassed at best. The compressor may have seized as well or if it hadn't before, will shortly after you hook it up unless you re-gas and oil the system.

In cool weather some people simply take that belt off instead of forking over the cash (perhaps a LOT of it) to have it properly repaired. I'm sorry to tell you, but if this is the case, there are no short cuts or cheap fixes... well I don't know of any.

Yup, happened to me. But, long enough ago, so I can chuckle!!
Twas my very nice 85 Ford F150 4x4. The AC was capable of freezing cold. Great output and a small space to cool. But, the compressor had been making awful noises for a time!! I knew it was on it's way out. One hot day, I awaited my late wife with her poodle in the car. AC on and tunes of some kind. Possibly Marty Robbins or Johnny Cash. Ellen liked Marty's music!!!
Then, a horrendous screech!!! It is here!!! Yup, compressor frozen and belt screaming. I think it was a separate belt, so I cut it and we went straight home.
Son, tom, got a friend to replace it and some other stuff and charge it again.
Great AC again, but much quieter!!
Will I charge the Jaguar's AC this season. I dunno. mebbe. The jeep AC is still more than OK.

The vacuum reservoir is tucked up in the left wing just beside the brake booster. It's black so it's hard to see, a flat round can, 5 inches diameter, 1.5 inches thick with only one hose fitting to the rear.
