Ac display and lights are out, ac charged and compressor recently replaced. ac display and lights came on for a week or so and blew cold and worked fine, but now out for a long time. Checked/reset fuses, disconnected neg battery and nothing works. Mechanic told me a couple of years ago I needed a new computer, any ideas?

The problem might be that you got out of freon gas.

you have a short somewhere problably bad ground , or interferrance from alternaot overloading the circuit... check all ground securlely...if you cant locate it its not going to be cheap for a mech to locate the issue.. good luc kthough ( also check for loose wire behind the fuse box in car.

It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.

If you see wet spots on the compressor it would be an indication that the compressor is bad, however buy a can or refrigerant with leak dye in it and see if you can see where the red dye is comming out and that will be your answer. Rather than guessing which one it is check it that way so you will know what it is then I can tell you how much to fix it.
