AC clutch will not engage
Hey folks Im new here and hope I dont mess this up but I have a 95 S10 Blazer that the AC clutch will not engage when I turn on AC. Is there a relay for this? I have checked fuses and such but thought maybe there might be a relay or something. I just bought this and was told the AC works but who knows. Thanks in advance

Re: AC clutch will not engage
There are several relays and switches that control clutch engagement. The clutch cycling switch, located on the accumulator, will not allow the compressor to engage if refrigerant charge is low. It's best to check pressure, if low side pressure is below approximately 40psi, the cycling switch will not allow the compressor to engage.
