We still don't know for sure that it is a refrigerant problem yet, although it sounds like it may be. Why don't we find out, once and for all?
Jack up the side of the car so you have access to the compressor. Find the clutch wire and unplug it. Find a 12 volt source like a wire connected to the battery or a jump and start. Tap the wire from the compressor to the 12 volt source(if using the jump and start, make sure you connected the ground lead to the compressor body or the engine block, or chassis ground). You should here the compressor make a fairly loud click, click, click as you touch the wire to the 12 volt source. If that doesn't work, your compressor clutch is bad. If it does work, reconnect the wire and move to the trinary switch. Find a way to connect the two wires coming out of the trinary switch together. If you uncover the harness a bit, you should find where the wires are spliced into the harness. If you can unwrap the installation a bit on both wires, you can then connect them together. Once they are connected together, go inside the car and turn the AC on and off. Listen for the AC clutch click-click-click as you turn the system on and off. If you hear it, you have just verified that the system is low on refrigerant and the only thing you need to do is recharge it. And MAYBE find a leak. (OR the trinary switch is bad.)
If the above procedure doesn't work, you still have an electrical problem...
And by the way, how do you know your system hasn't been upgraded to R134a. If you can get a picture of the service fittings we could verify the type of refrigerant used.
IF this all sounds too complicated then simply make a boring drive down Ortega highway, hopefully when there is no traffic or highway patrol, and bring your car by. I will figure out your problem for free...
Take care, Scott
Ha ha, this is like the godfather, just when you think you are out they drag you right back in. So in a couple years, will maybe have it resolved. On the post of Nov 11 at 7:24, I indicated that what if I attached a aligator clip to a wire and placed it on the prong on fuse 10, and the other end of the wire had a female clip and placed it where the brown wire is on the switch and then see if the AC works? I did that and the compressor definately ticked when turning on the AC switch. So, I know the compressor and those wires to it works, right? That is why I think it is that switch at the dryer or low freon.
Below is a shot of the AC tubes & fittings at I believe the AC compressor. Does that show what type of refrigerant, or do I need a shot up by the dryer tubes?
