Attention: TDR Forum Junkies I was tweaking around with various things on my truck today. As I was cleaning up the tools, I left the truck idling with the defroster on high to dry out the seat because I left the window down in the rain 
The hood was still up. After about a 5 minutes of idling, there was a very loud POP, then a wooshing sound, and some mist shooting up from the front of the engine. The sound was freaky, I darn near soiled my shorts 
After some investigation I located the cause. The high pressure relief valve on the back of the A/C compressor had blown off. This was caused because I don't have my fan on right now. The condensor wasn't getting cold air, so it wasn't condensing the refrigerant and the pressure kept building. The only way I found out this had happened is because of the green dye put into the system when the refrigerant was changed about a year ago. The dye had sprayed all over the engine mount.
Well, it looks like this won't happen again.
