A/C '97 Grand Caravan

Thanks for all the wonderful help in the past—Our 1997 Grand Caravan with 170K loses more air conditioning every year so assume I have a slow leak. Is recharging something I can do myself with the new type cans offered by auto parts stores?
Also, I think the radiator fan no longer comes on, I never here it and the engine temp will go up when driving slowly around town.
Thanks, Dan

Have iit checked ny a menhanic. He’ll have the knowledge, training, and equipment properly do the job.

Could be the fan or the temp sensor.
Any Haynes manual will tell you how to check it out.
