Why is Freon is spewing out of a valve on the compressor under pressure ?

Driving at highway speeds - fans are irrelevant - RAM AIR is sufficient. Refrain from using air conditioner until repairs can be completed.. ( ‘May be’ able to use a/c - at highway speeds ONLY ) Also monitor engine temperature gauge - especially while in stop and go traffic or vehicle is stopped / engine idling. ‘Cooling fans’ repair should be top priority due to possible engine overheating - this is not a diy friendly repair ! Highly recommend seeking *hands-on* assistance from qualified personnel. Good luck!
