my 1993 fd turns off when i turn the ac on wtf is going on it never did this before so i just dont tuurn it on any more

 

Do you get the feeling that it is an electrical or mechanincal problem? Does it squeal at all before it shuts down? I suppose it's possible that the AC compressor locked up and when the clutch engages, it stops the engine.

 

it dosnt make any noise its just like turning the car off
