What happened to a/c in my 97 Aucra RL. A/C worked fine last summer.

Well it could be many things. We need to find out if you stem is full and then that will tell us if you need to have a leak repaired or some electrical diagnostic work done. Please do not install any freon from the auto parts store. They contain a sealant that will damage your system and also damage our ac equipment. You can call us at 248-643-7690 and schedule an appointment.
