For some reason my ac compressor keeps cycling on and off. I have had the car for 11 years and this is not normal. I have replaced the compressor (done it myself) but did not take care of the problem. This is not my first time that I work on AC units, but this my first time that I I am not able to solve my problem. I have also replace the drier and also the expantion valve. but to no avail. Is it time to replace the Condenser. Please reply.

Thank You In Advance

If compressor cycling ON OFF
that is an indication of two things
low pressure and low 134A gas
or to high pressure (to much 134A)

need to check if low side too low and or if high side too high
I would suspect :
low 134A
cycle switch
high pressure switch
restriction in the system
good luck

I already replace the pressure switches but still the same problem. Cycling very rapid 5 to 6 times in about 5 sec.
