I have a simple A/C question. My clutch won't engage, and I suspect that I am low on freon. I want to manually override the clutch. A quick google search shows how to do this by bypassing the clutch relay, but I do not find such a relay in the box under the hood. I have the automatic climate control. Is my best option just to hotwire the compressor straight to my battery? If so, which terminal is positive vs. negative on my compressor connector? i hope to be able to engage the clutch and then add freon to see how quickly it leaks down before I take it to an A/C shop that will probably charge $200-300 just to check it out and recharge it.
