105 psi? If so that is way to hi...especially for a mid-sized car. You ideally want you pressure to be between 40-50 psi. If you pressure is that hi you might have blown the pressure valve on you compressor, which is not a part that is sold seperately. You should take your car to your local Pep Boys and have them run a A/C diagnostic which runs around $45 to give you an better idea. If you don't know what you're doinf the A/C system is not something you want to play a guessing game with. Especially since it's illegal to work on it without the proper tools and licenses.
