Hey,
I agree with your blockage assesment. That's exactly what I was thinking.

I put the leakstop in because there was a leak. I didn't notice it was the expansion valve until yesterday when I was removing the instrument cluster.

The compressor has always worked fine it just doesn't shut off. The previous owner had a service ticket concerning the AC. All they did was pull a vacuum and recharge though. The ticket doesn't say they did anything else.
Don't worry I won't be going to them for repairs.
Anyway, these AC problems aren't something new, i'm just more active in getting to the problem and making a final fix.

Once in a while I can hear the TEV valve spit out some refrigerant into the evaporator. It's just a short hssing sound.

I was wondering if the ETR valve would cause problems like this also but i guess if I'm replacing the TEV then I'll just replace the ETR valve also.

Thanks

Danny
