Yahoo!!! The Bronco's got AIR! :)

Thanks so much to Electro and his willingness to share, and help.

My compressor was not coming on.
I had a broken connection to the Pressure Sensor Switch
oh yeah, and a bad switch. I jumpered the switch like electro said to

and the compressor came on.

I repaired the connector, and replaced the switch, and the compressor was short cycling. Next step was to add freon.

Thanks electro! You da man! :)

Glad things worked out Poppy! :thumbsup:
Using a refrigerant with dye might also be helpful in finding the cause of any leakage. Remember that when adding refrigerant, one must use caution not to overfill the system, causing poor performance and component failure.

Sometimes less is more... :skep:

My son said that the last time he added freon, he added dye. That was a few years ago, is the dye still good?
Do I need a UV light to find the leak?

UV dye can sometimes be quite visible without any special equipment (http://www.fordforumsonline.com/for...ing-cooling-systems/1599-windstar-rear-c.html ), but in dry, dirty, greasy areas, a UV light will allow the dye to "fluoresce" which greatly enhances the visualization. Special yellow glasses further enhance the contrast of the dye over the background. I have found that bright sunlight or shop light reduces the chance of spotting the dye, while dark inspection areas increase the effectiveness. Since the dye is an oil based substance, it does not easily wash off.
