Ok, I am a newbie to Benzs here. I ran the DIY diagnostic AC to pull the codes and two came up; 234 sun sensor and 416 coolant circulation pump. I bought this car for my mom because it has high safety ratings and it only had 60,000 miles on it at the time of purchase.

1st question: Is there a website that I can find these parts?

2nd question: are there videos that I can watch to perhaps replace the parts myself?

Any help is greatly appreciated.

Neither the recirculating pump or the sun sensor will keep the AC from functioning. Run the diagnostics again, and post the results of values 1-8. These results will help pinpoint where the problems are.

FYI there are two tests-the actual value and the fault---you did the fault test now like advised do the actual value test which is also in the stickies!!

msolorio3

thank you for the help. where are the stickies?

RichM

Follow the instructions in part 1. Post back with values 1-8.

Ok, ran the diagnostic like you told me and came up with the following:
1-80
2-84
3-80
4-82
5-82
6-161
7-02
8-80

What does it mean?

Plutoe

It means that you are very low on refrigerant or your compressor can't make pressure!!

What do I do next, you say--you find an experienced AC shop have him put gages on your system----find the leak, if low, if not low replace the compressor and get on with your life!!

msolorio3

I already replaced the compressor, I hope its now just a matter of refrigerant.

RichM

When was the compressor replaced? Who replaced it? Assuming the system was evacuated and recharged correctly with the proper amount of refrigerant you obviously have a leak somewhere. Get some gauges on it, and find the leak. As Plutoe said, find an experienced AC shop.

I ran the diagnostic and keep coming up with 419 and 234
Electromagnetic clutch and sun sensor. How do I fix this?

RichM

You take the car back to the shop that replaced the compressor, and have them make it right. The sunsensor will not keep the AC from functioning.

Ok, took the car into the shop today. Just waiting to hear back from them. My fingers are crossed. Thanks for everyone who gave me their input along the way.

no feedback yet?

Yea and I don't wanna talk about it. Lol

Turns out the nice guy that I had trusted had done a terrible instillation. Thankfully, I found a good shop with a strong customer base and the mechanic was able to correct the installation of the compressor. Mechanic even said that the dryer wasn't installed correctly either and that there wasn't any r-134 in the system!

Oh well, I've learned not to be so trusting towards people just because they are nice; doesn't mean that they are competent people. And thank you to everyone who offered their advice and direction. It's much appreciated!

BTW, Anyone want to buy a 2000 E320 with 63,000 miles on it? :-)

Plutoe

Put and ad in any South American newspaper they need well maintained MB cars that have an excellent AC system!!
