Thank you all for this info. I think I have enough to go on for now.

I have not measured any voltage directly from the relay or the pins in the fuse box. I have only noticed that the relay is closing and the compressor clutch is engaging when the key is out and car is off. It does seem to happen mostly when the car/relay is warm.

If you’re like me, when you are trying to help someone you want to know the outcome. I won’t be able to get back to you until later in the week or possibly this weekend, but I thank you for this information.

Thanks!

Thanks, ToyotaKarl. I actually did try that previously, but got no real results. I was not able to get the relay to switch on while doing this test. I can try again, but it seems to be intermittent. If 12 volts is supposed to be supplied to that relay even with the key off, then I can go ahead and replace the relay. Does anyone know if 12 volts should be present at the AC compressor relay at all times?
