Perhaps someone can help:

The A/C has worked OK this summer untill now. Everything runs but it does not get cold. When I put my hand on the sensor on top of the dryer it turned and some gas escaped. It should not have been that loose. The window above the dryer appears dark when off and green flows through with bubbles when on. My question is can I just add some 134a without getting too involved. Or do I have to take it to an A/C guy. Is there any documentation on these units; manual, parts list, manufacturer, pressure levels, etc?

Hi Art. I don't know of any manuals. They used the stock AC system so if you can come up with a maintenance manual for the S-10, you can probably figure out the pressure it is suppose to be at. The question is, do you have the right equipment to add the right pressure? If not, any maintenance shop should have the skills to fill your freon for you. Smile

Thanks for the reply Major we solved the problem by going to Advance Auto and picking up some replacement R134a. What is interesting is that it came in a convienient container with a hose and small gauge with snap on hose fittings. The container is about a foot long and you run the AC while using it, shake it up good and attach to the low side port, it gives you pressure readings that show the level of the refrigerant in the system.
You can add refrigerent as needed. It worked amazingly well. This is not a fix for real problems but does seem to work for systems that are just low on refrigerant.

Glad it worked Art. Now I guess I'll have to try mine. My biggest problem right now is replacing two mosfets in my A/C controller. Confused
