    Yes it should set a low refrigerant DTC. Just get the refrigerant, not one with a sealer in it. You will have to figure out why the compressor is not running to add refrigerant. Usually all you have to to is clear the DTC to enable the compressor. If you do not have one, then there is another problem and the system may not need a charge.

Also i tried to do a search on how to do the dic hack for 94's but didnt have any luck, does anyone know the title?? or link maybe? Thanks alot
