Customer Question

Was the A/C working before you added freon to the system?

Customer: replied 1 year ago.
it was working it would not take freon
Customer: replied 1 year ago.
the check cooling fluid came on a day or to before this happend.
Expert:  Eric Gardner replied 1 year ago.

So, I am thinking that the freon charge is to high and the high pressure cut off switch on the has cut power to the compressor. Do you have access to professional A/C pressure gauges? If so I can walk you through the process of getting the correct amount of Freon in the system.

i did not put freon in cause the compresser wont come on and i can get a ac pressure gage at auto zone is that the right kind of ac gage .

Looks like you have done some research on this issue. There were many of these cars where the torque convertor is the culprit, but before you get to this conclusion I would try a few cheaper things.

I don't think the coils would be an issue. I can certainly send you diagnosis charts on how to check the the coils.

After all you have done, I would think the torque convertor is the issue. If you will kindly rate my service as 3 stars or above I can walk you through the torque convertor diagnosis.
