I just purchased this car and found that the A/C wasn't working. I have located the high pressure switch but i cannot find the low pressure switch. Can someone please tell me if there even is a low pressure switch. Thanks Tom

Hello, I'm Danny.

To answer your question. No, there is only a high side switch to prevent damage to system/compressor in case of malfunction or extreme high pressure.Hope this helps and thanks for using 2CarPros.
