Have to brag a little. My 06 Grand Marquis (111,000 miles) Climate Control went on the fritz during the Winter: everything came out of the defrost & floor, nothing out of the dash vents. During the winter this was bearable but now that it started warming up comfort came first. Troubleshooting showed a faulty control head and research showed this to be a common FoMoCo problem. Dealer wanted $650+ for a new one and $200+ for labor. You could find rehabbed used ones $99-$225 online. More research showed the problem in 90% of the cases were the factory, natural rubber "o" rings inside the control; they apparently get dried out and brittle and no longer seal the solenoids they are installed in. Well armed with a "how to" from a Crown Vic forum and $10.00 in silcone "o" rings I attacked it Friday. 2 hours later and it works as advertised and I saved almost $900 (dealer prices). Quite a feeling of accomplishment when that much dollar difference is involved! Final plus is the silicone rings are an upgrade from the factory standard so it should last a good long while. :banana-rock:
