So my AC is low and I decided to fill it up with propane. For the first time ever the electric fans kicked in on thier own. So clearly the system is presurizing better.

But... The compressor clutch stays on full time now. I also had my very first under-hood fire! Can now join that club! Is that relay, under the booster, related to compressor clutch or fan control?

I would search for help in old threads, but I am on my phone with no net around. And with the car behaving this way, I don't want to drive it much. BTW, pressure readings look fine. And if you question the use of propane, google it! Thanks.
