I'm getting alot of condensation on the Accumulator/Drier, which is dripping (almost running) down onto my exhaust, smoke smoke smoke.

Do I need another Accumulator possibly?

BTW, I've been coming here for over a year, reading all the tips posted in this forum...saved myself thousands of dollars.

Thanks , you guys rock!

My condensation drips on my exhaust, I get a sizle sound but never seen smoke.
 
RE: A/C Q

Be happy you are getting condensation on the Acc./Dryer. That means your A/C is working at full capacity. You should also be getting very cold air and operating your car in a very humid atmosphere. I would not worry unless the A/C is not very cold. There could be a restriction in the car's evaporator coil. Not referigerant, but air. Make sure all the vents are open or turned to the side. Use the automatic setting as much as possible. That will keep the system normal. Check out the compressor run time and the compressor idle time. Make sure you know the outside temperature when you do this. There is a graph in the service manual. Do all of this and post it and also give the year of the car. I have '94, '95, & '98 Service manuals, but they all should be the same because of the same R-134a referigerant used in all models. Another way is to check pressures, but you don't need to do that yet. And you may never. I don't reccomend it to people who do not know how to use a guage set, and I don't know your knowledge of expertise in this area. So, no offense intended and safety first.

Cool! I probably don't have anything to worry about then :)

I don't have any experience (yet) working on A/C, but I'm willing to learn. :)

The air is ice cold, but on mid 90's days it seems to cycle pretty often, and it seems to really put a drag on the motor...I feel it when the compressor comes on now more than I used to.

I've also noticed when the A/C is on the car runs hotter, climbs up to the top quarter of the "normal" range on the guage. I'm thinking I have a thermostat going bad, sticking open possibly, because on the highway the temp guage drops pretty low.

I'll go ahead and do the tests you sugessted and then repost what I find.

Thanks!

Thats how its supposed to be on the first gens. On the 2nd, it doesnt move AT ALL after it gets to the center.
 
RE: A/C Q

According to the service manual, if you are using the system in the mid 90s, the compressor should not shut off at all unless there is a lowering of the temperature inside the car. In order to really test it, you need to leave the doors open and see if the compressor cycles. It shouldn't. The service manual has a 90 degree limit of cycling. Both on and off. After the temperature lowers inside the car, the compressor should start to cycle. Once it is close to the set temperature, the air should be getting the air from the outside and the compressor should run longer than if it was getting the air from the inside of the car. If you leave the EATC controller on MAX A/C, the compressor would eventually start to cycle alot. That would also keep much of the cold water on the accumulator. Make sure you use the automatic setting on the EATC controller. Just set it at 70 degrees (or so) and let the system do its thing. That is the most efficient way of operating the system. If your compressor is rapidly cycling on and off, there is a problem - either in the system or the operation. It is to start cycling at about 50 degrees for an off time of about 18 to 25 seconds and then on for about 10 to 28 seconds. At 90 degrees it is supposed to run for about 2 1/2 minutes and shut off for only25 seconde. The book goes no higher than 90 degrees.
