Semi-Unique A/C Help

hey everyone, I need y'alls help on an A/C problem.

heres the deal...In june I had my A/C system converted to r134a and the drier bottle/switches replaced while I still lived in MD. 2 years before that I had the compressor replaced, but not converted at that time. Drove the car all the way to Del Rio, TX and the A/C worked fine. Mid-august, the AC dies on me.

I charge it with leak detecting freon and it runs for 1/2 a day fine. Once it dies again I look and see alot of fluorescent around the dryer bottle, so much that it is pooled around the bottle and forms a ring on the sheetmetal around the bottle when viewed from the bottom of the car. Fluorescent is also running down the bottle, but no obvious point of origin with the leak.

What do you guys think I need to do to get this A/C running again. Hell Rio is really hot. Unbearably so.

Taking it to a shop is not an option, here in Del Rio e30s are almost unheard of, and no mechanic speaks enough english to understand what I am telling them. They also don't want to work on it to top it all off.

Oh and FYI...I think the heat coming off the turbo (which was incredible) caused this problem while driving 12-14 hrs a day across the country. I have since solved the problem by insulating the turbo and downpipe. Sorry for the long post, but wanted to give as mush info as I know.

I lived in Texas for 3 years. The AC dying in mid august is like an astronaut's oxygen leaking into space.

Good luck.

Probably leaking fittings in the hose/s or switches on the receiver drier. Could just be loose as well since you swapped the drier. But it's hard to be sure without actually seeing it. Pics?

Haha tru that. This, among several other factors actually prompted me to buy a daily driver. I made sure it had really cold a/c.

here is the picture:



dye was accumulated on the bottom of the green piece, which is the High-pressure switch.

I couldn't get the dye to show up with the camera, but all the oily stuff is freon dye, to give you an idea what i'm working with.

If you put an ear down there it sounds like rice crispies when you first put milk on them

I'm thinking I should just replace the high pressure switch and see where that takes me, but other opinions are greatly appreciated.

Finally, I checked and the switch is tight. I am almost convinced it was damaged by heat from the turbo, which is roughly one foot away and above from these components.

Thanks for any help you can give!

I'm inclined to agree with what I can see......try the switch first.

You have a switch? I think I've got a good one.
