The hold light flashes then the air conditioning stop working. If we unplug the battery for a few minutes then plug back up everything resets and works for a few days then does it again.
Do you

This problem has nothing to do with the ac. If any sensors stop working on engine the computer shuts off a.c. and flashes HOLD light. The hold light flashing is the issue which usually means the turbine speed sensor needs to be replaced.

To be sure lets run the codes
