when air conditioner is on the blower will work sometimes and sometimes not.

Thanks so much. I will get that checked out.

Thanks, I will have it checked out. A/C was working fine then stopped blowing. Raised Hood and the A/C Compressor was cutting in and out ( short periods between activation ) but Not Blowing. Could this be some kind of Fuse or Relay? 2005 Grand Marquis L.S. Ultimate, 56,000 miles. Confused ? ? ?

I had blower controller replaced and everything is fine now.
