[camaro8484]

i have a 1998 chevy k1500 5.0 v8, i bought this truck a year ago when i first got it i bought the r134a or w.e it is at walmart put it on the line put some in it went up to 45psi , the clutch would engage then shut right off then it would engage n shut off it would keep doing this, then after while it just doesn't engage ne more any one have any input on if its the compressor its self if its the system just needs a recharge or what???? thanks guys i appreciate it!

needs more of a charge when charging it disconnect the pressure switch on the accumulator and jump the plug with a paperclip before you ad the freon

Yeah sound's like it need's more charge to me also, and yeah like mentioned jump the low pressure switch to force the clutch on and then charge it.
