I have a 2012 Ford F150 eco boost 4x4. The air would blow cold for a day or so but then I could stop at a red light and all you hear us a loud PSSSSSSSSHHHHHHH from under the truck and refrigerant was blowing out the bottom of the truck. I assume from the valve on the compressor. Sent to shop and he replaced expansion valve and filled refrigerant again. Another day or so later it did the same thing. Went back to the shop and he replaced the compressor. Once again, two days later starting psssshhhhh out the bottom and ac went hot again. Just took back to the shop and he replaced the condenser, expansion valve and has the gauges near perfect. If this doesn’t fix it, what do y’all think it could be? Thanks!!
