I have same problem the ac seems full of r134 it spits out and seems over charged but my truck does same thing until compressor engages . The Crossfire compressor spins freely but does not engage the light comes on the dash and the cooling fan spins but no ac. so not sure what you did to fix yours just thought I would ask you with out going through all these posts
Thanks

 

Hey Zip439,

Wish I knew what wire you speak of My ac compressor does same as guy who posted this I am afraid of damaging things further with my luck I will short out whole car or cause a fire LOLO you need a degree from M.I.T to work on any car these days Thanks if you could be more clear on this or take pics be very helpful for us older dudes who don't have this kind of info or nerve to eff things up more

thanks Manlaw38

 

Did Ed ever find out why his AC didn't work ?? I am having same issue my fuses are ok and system seems to be over charged I bought car with non working ac . I read someone said you can got in the box on fire wall and bypass a wire to the compressor but Im scared as hell to do this to screw things up more :confused :
