A/C codes 01 e320
Hi i posted a question on how to check if my fan was working- i got some help and figured out the fan motor works by jumping it from the battery.
**my a/c hasnt worked for years, but fan recently/10,000 miles ago or so stopped turning on** i didnt really get involved in the a/c diagnostics cause i thought it would just cost to much to repair so i suffered through the heat.
i was lurking the forums and youtube for some answers and i found a video that showed how to pull codes from the climate control deck inside- so i did and this is what i got
first test codes: which i am clueless to the meaning???
1 93
2 85
3 98
4 100
5 96
6 123
7 00
8 89
9 27
10 .8
11 2.4
12 4.3
20 3.2
21 32
22 00
23 32
24 11.2
40 16.4
41 91
42 104
43 136
Second test codes:
E61 416 coolant circulation pump- is what the videos legend said
E61 234 Sun sensor???
not sure where to go from here? help!!!!

Out Of Control!!
Well clueless, most folks will show some iniative and research the stickies for what things mean---I know no time!!
3 and 4 indicate that that your duovalve may be opening and allowing hot coolant to flow---no good
5--way to high should be in the low 40's
7--should be 15 to 17 bar
8--way to low
Overall and assuming you did the test correctly, your compressor is either shot or there is so little refrigerant that it can't produce the pressure causing 5 to be way high. Additionally test the duo valve may be open when should be closed in cooling cycle and open in heating
See a pro you are way over your head technically!!

OK thanks!!! i did some further testing, my duo valve needs a cleaning for sure, and the auxiliary water pump/circulation water pump or whatever you want to call it isn't working yet its receiving voltage so i ordered a used oem one off ebay, it was cheap enough to see if it will work, and i havent bothered refilling refrigerant thinking it would "leak" or so i thought like last time. so if this doesnt fix it then i will take it in to my mechanic and see what else might be up.

Repairing these items are good, but will not fix the lack of refrigerant in your system. You need to have the system leak tested, repaired if necessary then recharged.
