Hey all!
Found the AC in our 1999 5.4 EB Expedition was not blowing cold. Grabbed some freon (with the gauge built in) and went to fill it up. Noticed the clutch was not clicking on (only the pulley was spinning), so added freon till it got to 35 as I read on this forum that if its less than 20-25 it won't kick on.
Still didn't turn the clutch. So I found a trick on here to use a paperclip and jump the lowside switch. Sure enough, the clutch kicked on. Woo Hoo! Found the problem!
Ordered a new switch and installed it today. Turned on the truck, and nothing. Still not turning the clutch on the compressor. Tried the paperclip thing again, and it turned on.
Soooo, with that said, what else could it be? Gauge reads "35-40" when I attach it to the low end port.
Thanks for any advice guys. Really appreciate it!
