A couple of times in the past month I have aske for help with my A/C compressor cycling very rapidly. I had replaced the low pressure switch (pressostat), because the original one had failed causing the compressor not to come on at all. The new switch allowed the compressor to engage but cycle at a fast rate. I had the vendor send me anouther new (volvo oem) switch. It did the same thing as the first one.
After checking all leads and following all advise, I found and ordered an aftermarket switch not connected with volvo in any way.
IT WORKS! What are the odds that I got two bad pressure switches? I'll be making a nice call to the first vendor Monday mornnig.
Good weekend,
Chris
