Filter Dryer (in a car) - Click HERE for Original Thread
Christian
I know this has nothing to do with diyaudio, but since there's so much knowledge here I will give it a try.
I've encountered a problem i my car, a Mercedes CE300. There's a small "dc-engine looking" thing under the hood that isn't plugged in, the kables from it (four of them) are just hanging loose with some relays attached to them.

It reads Filter Dryer on the side, but by browsing the web I've found it could also be called accumulator. Does anyone know what this is?? and if so, does it have anything to do with the airconditioning system, which doesn't work.

Any answers are very welcome, I can post pics just ask.

Best Regards,

If your Air-Con doesn't work and this thing looks like it's disconnected...

You should post some pics. Maybe some of the car guys can be more helpful.

They are most likely pressure switches. They are for protection of the compressor. If the freon pressure is to high or low they shut down the compressor so it won't run dry or create too much pressure.

I can remember doing some work on an eagle tour bus with some problems related to these switches. It had quite a few of these since its compressor was extremely expensive. Thankfully that piece of junk is sold now.

you need the manual -- I know you are in Sweden, but there are several people who sell the complete manuals on CD-ROM via EBay.
