Hello,

Looking for help on an A/C Leak. 1999 ES300. A/C was not working when car was purchased (about a month ago). I filled the system with R134a (jumped the compressor clutch) and the system stayed cold for about 5mins. I ran a dye test and the dye shot out of a nipple on the back of the compressor (see photo). Anyone know what this is? Have you experienced this before? Common issue?

BUMP,

What I thought was the source of a leak was actually a pressure safety valve. I had over filled the system and valve opened.

I evacuated the system, then ran vacuum, then refilled the system. No leaks. The gauges have perfect readings. The problem is the compressor won't click on (unless manually jumped). I played with the safety pressure switch at the receiver/drier. I removed the connection and the a/c fan turned on immediately, but the compressor still didn't kick in. Hmmmm. I'm suspecting my pressure switch.

Stilll needing advice on this.
