i just took the valve apart and cleaned it inside very well...

removed the gunk inside and cleaned it with wd40..

put everything back together and turned the car on as well as the ac.

my ac certainly did start blowing cold. I thought i had fixed it. but within 10 minutes is no back to blowing hot air again

ac compressor is working fine, my cooling fan is working fine, my ac is charged becuase i feel the ac line cold.....could it be a leak???? the water control valve is bad??? but why did it blow cold for 10 min.......should i get an original one? try my luck with another used one or go to the dealer!!!!!????? ahhhhh
