andrew55 Stranger Registered: 10/26/17 Posts: 2 Loc: Florida	I have a Crown Vic, 2003, LX. When I start up car, AC doesn't work - just regular air comes out. But after I drive a while and then sit at an intersection idling, the AC kicks on. Any ideas on what might be causing this issue or any suggestions on what can be done to fix it? Thanks for any help.

A 14 year-old system probably needs some loving attention. _________________________ Sig removed. Read the rules. So, I read the rules. Now I'm even more confused.

I've had a flakey low pressure cause delayed start up, someone on here had issues with the compressor relay doing same... A inoperative cooling fan can do same but engine should be running hot... _________________________ 1998 Grand Marquis LS. 96K mi. .. Stock 2007 Grand Marquis GS. 90K mi. ..
