compressor clutch

[alfredo novo]

The clutch on my ac compressor has this stop and go thing going on. It doesn't matter wheather the AC or the heat is on. Everytime the clutch stops, the RPM's drops almost into a stall situation and then the clutch engages again. The cold and hot air blows fine. Any Ideas??? :wacko:

Low on R134A....



And the St compressor will cycle in almost any position except off... If it is doing it in OFF then your slightly low on 134A.
