Hi guys,

Not sure if I'm the only one experiencing this.

My A/C normally works OK and as expected.

HOWEVER, when the weather is TOO hot outside and my oil temps rise to the 200°F range, the A/C compressor simply starts to act up and shuts down randomly and after a little while turns back on, and shuts off again, and so on.

The A/C fan blowers continue to work, it's the compressor itself that stops functioning. So, when it turns off, the "A/C" it's simply blowing "hot" air, and starts blowing "cool" air again once the compressor turns back on.

It becomes a cycle and ranges between 30 seconds to a full minute until it shuts down again and same for it to turn back on.

It will happen whether I'm driving or in traffic, but it's more common during traffic.

I almost never get oil temps above 195°F because I have an oil cooler installed and I've noticed that as long as I'm there or below that temp, A/C works perfectly.

Any insights on what this might be?

Thanks in advance for your input.
