The AC on my 2002 Lightning hasn’t blown cold for a LONG time. It had a leak somewhere that I never really worried about fixing. Well I decided to fill it up today.
I got it all filled up nicely and got the air blowing ice cold. When I turned off the engine: After several seconds I hear a loud hissing sound coming from under the truck. This sound only last about 5-6 seconds and then suddenly stops. I hooked the gauge back up and noticed the pressure dropped a few pounds.
I crawled under the truck and tried to find the source of the sound. The only thing I can figure is that it is coming from a crimp on the low side hose. The pipe where it turns to go to the compressor was wet, It was the ONLY place on the entire truck that was wet.
The fact that the hissing is delayed and also temporary has me puzzled.
What are your thoughts on this? Bad hose crimp? Should I replace it?
