Hi,



Thank you for asking your question on JustAnswer. The other Experts and I are working on your answer. By the way, it would help us to know:



-Does the compressor clutch engage when the A/C is turned on?


-What else have you already tried?

Hi,

 

 

 

Thank you for asking your question on JustAnswer. The first thing to check is the A/C clutch relay in the BJB (Battery Junction Box), and electrical connections, (just in case they were accidentally disconnected). If you need I cxan send the pinpoint test procedures in order to determine the exact cause.

 

  • The air conditioning (A/C) is inoperative/does not operate correctly
  • Fuse(s).
  • Circuitry short/open.
  • A/C cycling switch (19E561).
  • A/C system discharged/low charge.
  • A/C pressure cutoff switch (19D594).
  • EATC module.
  • Function selector switch.

OK - i will check all those........Do you know where the fuse and/or cirut would be for a 2003 crown vic ?

 

Do you think it could have anything to do with me replacing the coils or just a coincidence ?

Hi,



Thank you for asking your question on JustAnswer. If the A/C was working properly before the repairs were made, then most likely it was something that happened at that time, when the coils were replaced. If you need, I can send the pinpoint test procedures in order to determine the exact cause.
